anydb-sql

anydb-sql

anydb-sql combines node-anydb and node-sql into a single package.

examples and usage:

Initializing an instance also creates a connection pool. The url argument is the same as in node-anydb

var anydbsql = require('anydb-sql');

var db = anydbsql({
    url: 'postgres://user:pass@host:port/database',
    connections: { min: 2, max: 20 }
});

Defining a table for that database is the same as in node-sql:

var user = db.define({
    name: 'Users',
    columns: ['id', 'email', 'password']
});

Queries have the addtional methods:

• exec(function(err, rows)) - executes the query and calls the callback with an array of rows
• get(function(err, row)) - executes the query and returns the first result
• all - same as exec
• execWithin(transaction, function(err, rows)) - execute within a transaction

Use regular node-sql queries then chain one of the additional methods at the end:

user.where({email: user.email}).get(function(err, users) {
  // users[0].name, 
});

Join queries have somewhat different results at the moment. The format of the result is the same as with anydb

user.select(user.name, post.content)
  .from(user.join(post).on(user.id.equals(post.userId)))
  .where(post.date.gt(yesterday))
  .where(user.id.equals(id))
  .get(function(err, res) {
    // res['user.name'] and res['post.content']
  });

Create a transactions and execute queries within it

var tx = db.begin()
user.insert({name: 'blah'}).returning(user.id).execWithin(tx);
user.insert({name: 'bleh'}).returning(user.id).execWithin(tx);
tx.commit();

Transactions have the same API as anydb tranactions

Finally you can close the connection pool

db.close();

Or execute custom queries

db.query(...anydb arguments...)
