The mssql npm package is a Microsoft SQL Server client for Node.js. It allows you to connect to SQL Server databases, execute queries, and manage transactions. It supports both Promises and async/await syntax, making it versatile for different coding styles.
Connecting to a SQL Server
This code demonstrates how to connect to a SQL Server database using the mssql package. You need to provide your database credentials and server information in the config object.
const sql = require('mssql');
const config = {
user: 'your_username',
password: 'your_password',
server: 'your_server',
database: 'your_database'
};
async function connectToDatabase() {
try {
let pool = await sql.connect(config);
console.log('Connected to the database');
} catch (err) {
console.error('Database connection failed: ', err);
}
}
connectToDatabase();Executing a Query
This code demonstrates how to execute a SQL query using the mssql package. It connects to the database and runs a SELECT query on a specified table.
const sql = require('mssql');
const config = {
user: 'your_username',
password: 'your_password',
server: 'your_server',
database: 'your_database'
};
async function executeQuery() {
try {
let pool = await sql.connect(config);
let result = await pool.request().query('SELECT * FROM your_table');
console.log(result);
} catch (err) {
console.error('Query execution failed: ', err);
}
}
executeQuery();Using Prepared Statements
This code demonstrates how to use prepared statements with the mssql package. Prepared statements are useful for executing queries with parameters, which can help prevent SQL injection attacks.
const sql = require('mssql');
const config = {
user: 'your_username',
password: 'your_password',
server: 'your_server',
database: 'your_database'
};
async function executePreparedStatement() {
try {
let pool = await sql.connect(config);
let ps = new sql.PreparedStatement(pool);
ps.input('input_parameter', sql.Int);
await ps.prepare('SELECT * FROM your_table WHERE id = @input_parameter');
let result = await ps.execute({ input_parameter: 1 });
console.log(result);
await ps.unprepare();
} catch (err) {
console.error('Prepared statement execution failed: ', err);
}
}
executePreparedStatement();Managing Transactions
This code demonstrates how to manage transactions using the mssql package. Transactions allow you to execute a series of queries as a single unit of work, which can be committed or rolled back based on success or failure.
const sql = require('mssql');
const config = {
user: 'your_username',
password: 'your_password',
server: 'your_server',
database: 'your_database'
};
async function manageTransaction() {
try {
let pool = await sql.connect(config);
let transaction = new sql.Transaction(pool);
await transaction.begin();
let request = new sql.Request(transaction);
await request.query('INSERT INTO your_table (column1) VALUES (value1)');
await transaction.commit();
console.log('Transaction committed');
} catch (err) {
console.error('Transaction failed: ', err);
if (transaction) await transaction.rollback();
}
}
manageTransaction();The mysql package is a client for MySQL databases. It provides similar functionalities to mssql, such as connecting to a database, executing queries, and managing transactions. However, it is specifically designed for MySQL databases.
The pg package is a PostgreSQL client for Node.js. Like mssql, it allows you to connect to a database, execute queries, and manage transactions. It is tailored for PostgreSQL databases and offers features specific to PostgreSQL.
The sqlite3 package is a client for SQLite databases. It provides functionalities for connecting to SQLite databases, executing queries, and managing transactions. Unlike mssql, it is designed for lightweight, file-based databases.
An easy-to-use MSSQL database connector for Node.js.
There are some TDS modules which offer functionality to communicate with MSSQL databases but none of them does offer enough comfort - implementation takes a lot of lines of code. So I decided to create this module, that make work as easy as it could without losing any important functionality. node-mssql uses other TDS modules as drivers and offer easy to use unified interface. It also add extra features and bug fixes.
There is also co wrapper available - co-mssql.
Extra features:
At the moment it support three TDS modules:
npm install mssql
var sql = require('mssql');
var config = {
user: '...',
password: '...',
server: 'localhost', // You can use 'localhost\\instance' to connect to named instance
database: '...',
options: {
encrypt: true // Use this if you're on Windows Azure
}
}
var connection = new sql.Connection(config, function(err) {
// ... error checks
// Query
var request = new sql.Request(connection); // or: var request = connection.request();
request.query('select 1 as number', function(err, recordset) {
// ... error checks
console.dir(recordset);
});
// Stored Procedure
var request = new sql.Request(connection);
request.input('input_parameter', sql.Int, 10);
request.output('output_parameter', sql.VarChar(50));
request.execute('procedure_name', function(err, recordsets, returnValue) {
// ... error checks
console.dir(recordsets);
});
});
var sql = require('mssql');
var config = {
user: '...',
password: '...',
server: 'localhost', // You can use 'localhost\\instance' to connect to named instance
database: '...',
options: {
encrypt: true // Use this if you're on Windows Azure
}
}
sql.connect(config, function(err) {
// ... error checks
// Query
var request = new sql.Request();
request.query('select 1 as number', function(err, recordset) {
// ... error checks
console.dir(recordset);
});
// Stored Procedure
var request = new sql.Request();
request.input('input_parameter', sql.Int, value);
request.output('output_parameter', sql.VarChar(50));
request.execute('procedure_name', function(err, recordsets, returnValue) {
// ... error checks
console.dir(recordsets);
});
});
If you plan to work with large amount of rows, you should always use streaming. Once you enable this, you must listen for events to receive data.
var sql = require('mssql');
var config = {
user: '...',
password: '...',
server: 'localhost', // You can use 'localhost\\instance' to connect to named instance
database: '...',
stream: true, // You can enable streaming globally
options: {
encrypt: true // Use this if you're on Windows Azure
}
}
sql.connect(config, function(err) {
// ... error checks
var request = new sql.Request();
request.stream = true; // You can set streaming differently for each request
request.query('select * from verylargetable'); // or request.execute(procedure);
request.on('recordset', function(columns) {
// Emitted once for each recordset in a query
});
request.on('row', function(row) {
// Emitted for each row in a recordset
});
request.on('error', function(err) {
// May be emitted multiple times
});
request.on('done', function(returnValue) {
// Always emitted as the last one
});
});
var config = {
user: '...',
password: '...',
server: 'localhost',
database: '...',
pool: {
max: 10,
min: 0,
idleTimeoutMillis: 30000
}
}

This driver is not part of the default package and must be installed separately by npm install tds.
This module update node-tds driver with extra features and bug fixes by overriding some of its internal functions. If you want to disable this, require module with var sql = require('mssql/nofix').
var connection = new sql.Connection({ /* config */ });
Errors
ConnectionError) - Unknown driver.close).Create connection to the server.
Arguments
Example
var connection = new sql.Connection({

// ...
});
Errors
ConnectionError) - Login failed.ConnectionError) - Connection timeout.ConnectionError) - Database is already connected!ConnectionError) - Already connecting to database!ConnectionError) - Instance lookup failed.ConnectionError) - Socket error.Close connection to the server.
Example

var request = new sql.Request(/* [connection] */);
If you omit connection argument, global connection is used instead.
Call a stored procedure.
Arguments
returnValue is also accessible as property of recordsets.Example
var request = new sql.Request();
request.input('input_parameter', sql.Int, value);
request.output('output_parameter', sql.Int);
request.execute('procedure_name', function(err, recordsets, returnValue) {
// ... error checks
console.log(recordsets.length); // count of recordsets returned by the procedure
console.log(recordsets[0].length); // count of rows contained in first recordset
console.log(returnValue); // procedure return value
console.log(recordsets.returnValue); // same as previous line
console.log(request.parameters.output_parameter.value); // output value
// ...
});
Errors
RequestError) - Message from SQL ServerRequestError) - Canceled.RequestError) - Request timeout.RequestError) - No connection is specified for that request.ConnectionError) - Connection not yet open.TransactionError) - Transaction has not begun.Add an input parameter to the request.
Arguments
undefined ans NaN values are automatically converted to null values.Example
request.input('input_parameter', value);
request.input('input_parameter', sql.Int, value);
JS Data Type To SQL Data Type Map
String -> sql.NVarCharNumber -> sql.IntBoolean -> sql.BitDate -> sql.DateTimeBuffer -> sql.VarBinarysql.Table -> sql.TVPDefault data type for unknown object is sql.NVarChar.
You can define your own type map.
sql.map.register(MyClass, sql.Text);
You can also overwrite the default type map.
sql.map.register(Number, sql.BigInt);
Errors (synchronous)
RequestError) - Invalid number of arguments.RequestError) - SQL injection warning.Add an output parameter to the request.
Arguments
undefined and NaN values are automatically converted to null values. Optional.Example
request.output('output_parameter', sql.Int);
request.output('output_parameter', sql.VarChar(50), 'abc');
Errors (synchronous)
RequestError) - Invalid number of arguments.RequestError) - SQL injection warning.Execute the SQL command. To execute commands like create procedure or if you plan to work with local temporary tables, use batch instead.
Arguments
Example
var request = new sql.Request();
request.query('select 1 as number', function(err, recordset) {
// ... error checks
console.log(recordset[0].number); // return 1
// ...
});
Errors
RequestError) - Request timeout.RequestError) - Message from SQL ServerRequestError) - Canceled.RequestError) - No connection is specified for that request.ConnectionError) - Connection not yet open.TransactionError) - Transaction has not begun.You can enable multiple recordsets in queries with the request.multiple = true command.
var request = new sql.Request();
request.multiple = true;
request.query('select 1 as number; select 2 as number', function(err, recordsets) {
// ... error checks
console.log(recordsets[0][0].number); // return 1
console.log(recordsets[1][0].number); // return 2
});
Execute the SQL command. Unlike query, it doesn't use sp_executesql, so is not likely that SQL Server will reuse the execution plan it generates for the SQL. Use this only in special cases, for example when you need to execute commands like create procedure which can't be executed with query or if you're executing statements longer than 4000 chars on SQL Server 2000. Also you should use this if you're plan to work with local temporary tables (more information here).
NOTE: Table-Valued Parameter (TVP) is not supported in batch.
Arguments
Example
var request = new sql.Request();
request.batch('create procedure #temporary as select * from table', function(err, recordset) {
// ... error checks
});
Errors
RequestError) - Request timeout.RequestError) - Message from SQL ServerRequestError) - Canceled.RequestError) - No connection is specified for that request.ConnectionError) - Connection not yet open.TransactionError) - Transaction has not begun.You can enable multiple recordsets in queries with the request.multiple = true command.
Perform a bulk insert.
Arguments
sql.Table instance.Example
var table = new sql.Table('table_name'); // or temporary table, e.g. #temptable
table.create = true;
table.columns.add('a', sql.Int, {nullable: true});
table.columns.add('b', sql.VarChar(50), {nullable: false});
table.rows.add(777, 'test');
var request = new sql.Request();
request.bulk(table, function(err, rowCount) {
// ... error checks
});
IMPORTANT: Always indicate whether the column is nullable or not!
TIP: If you set table.create to true, module will check if the table exists before it start sending data. If it doesn't, it will automatically create it.
TIP: You can also create Table variable from any recordset with recordset.toTable().
Errors
RequestError) - Table name must be specified for bulk insert.RequestError) - Request timeout.RequestError) - Message from SQL ServerRequestError) - Canceled.RequestError) - No connection is specified for that request.ConnectionError) - Connection not yet open.TransactionError) - Transaction has not begun.Cancel currently executing request. Return true if cancellation packet was send successfully.
Example
var request = new sql.Request();
request.query('waitfor delay \'00:00:05\'; select 1 as number', function(err, recordset) {
console.log(err instanceof sql.RequestError); // true
console.log(err.message); // Canceled.
console.log(err.code); // ECANCEL
// ...
});
request.cancel();
Important: always use Transaction class to create transactions - it ensures that all your requests are executed on one connection. Once you call begin, a single connection is acquired from the connection pool and all subsequent requests (initialized with the Transaction object) are executed exclusively on this connection. Transaction also contains a queue to make sure your requests are executed in series. After you call commit or rollback, connection is then released back to the connection pool.
var transaction = new sql.Transaction(/* [connection] */);
If you omit connection argument, global connection is used instead.
Example
var transaction = new sql.Transaction(/* [connection] */);
transaction.begin(function(err) {
// ... error checks
var request = new sql.Request(transaction);
request.query('insert into mytable (mycolumn) values (12345)', function(err, recordset) {
// ... error checks
transaction.commit(function(err, recordset) {
// ... error checks
console.log("Transaction commited.");
});
});
});
Transaction can also be created by var transaction = connection.transaction();. Requests can also be created by var request = transaction.request();.
Begin a transaction.
Arguments
READ_COMMITTED by default. For possible values see sql.ISOLATION_LEVEL.Example
var transaction = new sql.Transaction();
transaction.begin(function(err) {
// ... error checks
});
Errors
ConnectionError) - Connection not yet open.TransactionError) - Transaction has already begun.Commit a transaction.
Arguments
Example
var transaction = new sql.Transaction();
transaction.begin(function(err) {
// ... error checks
transaction.commit(function(err) {
// ... error checks
})
});
Errors
TransactionError) - Transaction has not begun.TransactionError) - Can't commit transaction. There is a request in progress.Rollback a transaction.
Arguments
Example
var transaction = new sql.Transaction();
transaction.begin(function(err) {
// ... error checks
transaction.rollback(function(err) {
// ... error checks
})
});
Errors
TransactionError) - Transaction has not begun.TransactionError) - Can't rollback transaction. There is a request in progress.Important: always use PreparedStatement class to create prepared statements - it ensures that all your executions of prepared statement are executed on one connection. Once you call prepare, a single connection is aquired from the connection pool and all subsequent executions are executed exclusively on this connection. Prepared Statement also contains a queue to make sure your executions are executed in series. After you call unprepare, the connection is then released back to the connection pool.
var ps = new sql.PreparedStatement(/* [connection] */);
If you omit the connection argument, the global connection is used instead.
Example
var ps = new sql.PreparedStatement(/* [connection] */);
ps.input('param', sql.Int);
ps.prepare('select @param as value', function(err) {
// ... error checks
ps.execute({param: 12345}, function(err, recordset) {
// ... error checks
ps.unprepare(function(err) {
// ... error checks
});
});
});
IMPORTANT: Remember that each prepared statement means one reserved connection from the pool. Don't forget to unprepare a prepared statement!
TIP: You can also create prepared statements in transactions (new sql.PreparedStatement(transaction)), but keep in mind you can't execute other requests in the transaction until you call unprepare.
Add an input parameter to the prepared statement.
Arguments
Example
ps.input('input_parameter', sql.Int);
ps.input('input_parameter', sql.VarChar(50));
Errors (synchronous)
PreparedStatementError) - Invalid number of arguments.PreparedStatementError) - SQL injection warning.Add an output parameter to the prepared statement.
Arguments
Example
ps.output('output_parameter', sql.Int);
ps.output('output_parameter', sql.VarChar(50));
Errors (synchronous)
PreparedStatementError) - Invalid number of arguments.PreparedStatementError) - SQL injection warning.Prepare a statement.
Arguments
Example
var ps = new sql.PreparedStatement();
ps.prepare('select @param as value', function(err) {
// ... error checks
});
Errors
ConnectionError) - Connection not yet open.PreparedStatementError) - Statement is already prepared.TransactionError) - Transaction has not begun.Execute a prepared statement.
Arguments
Example
var ps = new sql.PreparedStatement();
ps.input('param', sql.Int);
ps.prepare('select @param as value', function(err) {
// ... error checks
ps.execute({param: 12345}, function(err, recordset) {
// ... error checks
console.log(recordset[0].value); // return 12345
});
});
You can enable multiple recordsets by ps.multiple = true command.
var ps = new sql.PreparedStatement();
ps.input('param', sql.Int);
ps.prepare('select @param as value', function(err) {
// ... error checks
ps.multiple = true;
ps.execute({param: 12345}, function(err, recordsets) {
// ... error checks
console.log(recordsets[0][0].value); // return 12345
});
});
You can also stream executed request.
var ps = new sql.PreparedStatement();
ps.input('param', sql.Int);
ps.prepare('select @param as value', function(err) {
// ... error checks
ps.stream = true;
request = ps.execute({param: 12345});
request.on('recordset', function(columns) {
// Emitted once for each recordset in a query
});
request.on('row', function(row) {
// Emitted for each row in a recordset
});
request.on('error', function(err) {
// May be emitted multiple times
});
request.on('done', function(returnValue) {
// Always emitted as the last one
});
});
Errors
PreparedStatementError) - Statement is not prepared.RequestError) - Request timeout.RequestError) - Message from SQL ServerRequestError) - Canceled.Unprepare a prepared statement.
Arguments
Example
var ps = new sql.PreparedStatement();
ps.input('param', sql.Int);
ps.prepare('select @param as value', function(err, recordsets) {
// ... error checks
ps.unprepare(function(err) {
// ... error checks
});
});
Errors
PreparedStatementError) - Statement is not prepared.node-mssql has built-in serializer for Geography and Geometry CLR data types.

Supported on SQL Server 2008 and later. You can pass a data table as a parameter to stored procedure. First, we have to create custom type in our database.
CREATE TYPE TestType AS TABLE ( a VARCHAR(50), b INT );
Next we will need a stored procedure.
CREATE PROCEDURE MyCustomStoredProcedure (@tvp TestType readonly) AS SELECT * FROM @tvp
Now let's go back to our Node.js app.
var tvp = new sql.Table()
// Columns must correspond with type we have created in database.
tvp.columns.add('a', sql.VarChar(50));
tvp.columns.add('b', sql.Int);
// Add rows
tvp.rows.add('hello tvp', 777); // Values are in same order as columns.
You can send table as a parameter to stored procedure.
var request = new sql.Request();
request.input('tvp', tvp);
request.execute('MyCustomStoredProcedure', function(err, recordsets, returnValue) {
// ... error checks
console.dir(recordsets[0][0]); // {a: 'hello tvp', b: 777}
});
TIP: You can also create Table variable from any recordset with recordset.toTable().
There are three type of errors you can handle:
Those errors are initialized in node-mssql module and its original stack can be cropped. You can always access original error with err.originalError.
SQL Server may generate more than one error for one request so you can access preceding errors with err.precedingErrors.
Each known error has code property.
| Type | Code | Description |
|---|---|---|
ConnectionError | ELOGIN | Login failed. |
ConnectionError | ETIMEOUT | Connection timeout. |
ConnectionError | EDRIVER | Unknown driver. |
ConnectionError | EALREADYCONNECTED | Database is already connected! |
ConnectionError | EALREADYCONNECTING | Already connecting to database! |
ConnectionError | ENOTOPEN | Connection not yet open. |
ConnectionError | EINSTLOOKUP | Instance lookup failed. |
ConnectionError | ESOCKET | Scoket error. |
TransactionError | ENOTBEGUN | Transaction has not begun. |
TransactionError | EALREADYBEGUN | Transaction has already begun. |
TransactionError | EREQINPROG | Can't commit/rollback transaction. There is a request in progress. |
RequestError | EREQUEST | Message from SQL Server |
RequestError | ECANCEL | Canceled. |
RequestError | ETIMEOUT | Request timeout. |
RequestError | EARGS | Invalid number of arguments. |
RequestError | EINJECT | SQL injection warning. |
RequestError | ENOCONN | No connection is specified for that request. |
PreparedStatementError | EARGS | Invalid number of arguments. |
PreparedStatementError | EINJECT | SQL injection warning. |
PreparedStatementError | EALREADYPREPARED | Statement is already prepared. |
PreparedStatementError | ENOTPREPARED | Statement is not prepared. |
Recordset metadata are accessible through the recordset.columns property.
var request = new sql.Request();
request.query('select convert(decimal(18, 4), 1) as first, \'asdf\' as second', function(err, recordset) {
console.dir(recordset.columns);
console.log(recordset.columns.first.type === sql.Decimal); // true
console.log(recordset.columns.second.type === sql.VarChar); // true
});
Columns structure for example above:
{ first: { index: 0, name: 'first', length: 17, type: [sql.Decimal], scale: 4, precision: 18 },
second: { index: 1, name: 'second', length: 4, type: [sql.VarChar] } }
You can define data types with length/precision/scale:
request.input("name", sql.VarChar, "abc"); // varchar(3)
request.input("name", sql.VarChar(50), "abc"); // varchar(50)
request.input("name", sql.VarChar(sql.MAX), "abc"); // varchar(MAX)
request.output("name", sql.VarChar); // varchar(8000)
request.output("name", sql.VarChar, "abc"); // varchar(3)
request.input("name", sql.Decimal, 155.33); // decimal(18, 0)
request.input("name", sql.Decimal(10), 155.33); // decimal(10, 0)
request.input("name", sql.Decimal(10, 2), 155.33); // decimal(10, 2)
request.input("name", sql.DateTime2, new Date()); // datetime2(7)
request.input("name", sql.DateTime2(5), new Date()); // datetime2(5)
List of supported data types:
sql.Bit
sql.BigInt
sql.Decimal ([precision], [scale])
sql.Float
sql.Int
sql.Money
sql.Numeric ([precision], [scale])
sql.SmallInt
sql.SmallMoney
sql.Real
sql.TinyInt
sql.Char ([length])
sql.NChar ([length])
sql.Text
sql.NText
sql.VarChar ([length])
sql.NVarChar ([length])
sql.Xml
sql.Time ([scale])
sql.Date
sql.DateTime
sql.DateTime2 ([scale])
sql.DateTimeOffset ([scale])
sql.SmallDateTime
sql.UniqueIdentifier
sql.Binary
sql.VarBinary ([length])
sql.Image
sql.UDT
sql.Geography
sql.Geometry
To setup MAX length for VarChar, NVarChar and VarBinary use sql.MAX length.
This module has built-in SQL injection protection. Always use parameters to pass sanitized values to your queries.
var request = new sql.Request();
request.input('myval', sql.VarChar, '-- commented');
request.query('select @myval as myval', function(err, recordset) {
console.dir(recordset);
});
You can enable verbose mode by request.verbose = true command.
var request = new sql.Request();
request.verbose = true;
request.input('username', 'patriksimek');
request.input('password', 'dontuseplaintextpassword');
request.input('attempts', 2);
request.execute('my_stored_procedure');
Output for the example above could look similar to this.
---------- sql execute --------
proc: my_stored_procedure
input: @username, varchar, patriksimek
input: @password, varchar, dontuseplaintextpassword
input: @attempts, bigint, 2
---------- response -----------
{ id: 1,
username: 'patriksimek',
password: 'dontuseplaintextpassword',
email: null,
language: 'en',
attempts: 2 }
---------- --------------------
return: 0
duration: 5ms
---------- completed ----------
