SOQL Parser JS
Description
This library allows parsing and composing SOQL queries from Salesforce using JavaScript or Typescript.
Available Features:
- Parse SOQL queries into a common
Query
data structure. - Compose a
Query
data structure back into a SOQL query. - Validate a query to check if the syntax is valid. (Note: even if a query is returned as valid, it might still be invalid based on your Salesforce configuration)
This library uses Chevrotain to parse queries. Prior to version 2.0.0, antlr4 was used. The move to Chevrotain provided a significant performance increase and decrease in bundle size. :tada:
Migrating from version 1 to version 2? Check out the changelog for a full list of changes.

Quick Start
import { parseQuery, composeQuery, isQueryValid } from 'soql-parser-js';
const query = parseQuery(`SELECT Id FROM Account WHERE Id = 'FOO'`);
console.log('query', query);
const soql = composeQuery(query);
console.log('soql', soql);
isQueryValid('SELECT Id, Foo FROM Baz');
isQueryValid('SELECT Id Foo FROM Baz');
Available Features
Function | Description | Arguments |
---|
parseQuery | Parse a SOQL query string into a Query data structure. | soql: Query config?: ParseQueryConfig |

Utility Functions
Function | Description | Arguments |

Examples
Parsing Queries
Parsing a SOQL query can be completed by calling parseQuery(soqlQueryString)
. A Query
data structure will be returned.
import { parseQuery } from 'soql-parser-js';
const soql = `
SELECT UserId, COUNT(Id)
FROM LoginHistory
WHERE LoginTime > 2010-09-20T22:16:30.000Z
AND LoginTime < 2010-09-21T22:16:30.000Z
GROUP BY UserId
`;
const soqlQuery = parseQuery(soql);
console.log(JSON.stringify(soqlQuery, null, 2));

"literalType": "DATETIME"
}
}
},
"groupBy": {
"field": "UserId"
}
}
Validating Queries
import { isQueryValid } from 'soql-parser-js';
const invalidSoql = `SELECT UserId, COUNT(Id) Account`;
const validSoql = `SELECT UserId, COUNT(Id) Account`;
console.log(isQueryValid(soql));
console.log(isQueryValid(soql));
Composing Queries
Build a Query
data structure to have it converted back into a SOQL query.
Composing a query will turn a Query object back to a SOQL query string. The exact same data structure returned from parseQuery()
can be used,
but depending on your use-case, you may need to build your own data structure to compose a query.
These examples show building your own Query object with the minimum required fields.
Some utility methods have been provided to make it easier to build the field data structures.
Note: Some operators may be converted to uppercase (e.x. NOT, AND)
Note: There are a number of fields populated on the Query object when parseQuery()
is called that are not required to compose a query. Look at the examples below and the comments in the data model for more information.
import { composeQuery, getField, Query } from 'soql-parser-js';
const oppLineItemsSubquery = {
fields: [
getField('Quantity'),
getField('ListPrice'),
getField({
field: 'UnitPrice',
relationships: ['PricebookEntry'],
}),
getField({
field: 'Name',
relationships: ['PricebookEntry'],
}),
],
relationshipName: 'OpportunityLineItems',
};
const soqlQuery: Query = {
fields: [
getField('Id'),
getField('Name'),
getField({
functionName: 'FORMAT',
parameters: 'Amount',
alias: 'MyFormattedAmount',
}),
getField({ subquery: oppLineItemsSubquery }),
],
sObject: 'Opportunity',
where: {
left: {
field: 'CreatedDate',
operator: '>',
value: 'LAST_N_YEARS:1',
},
operator: 'AND',
right: {
left: {
field: 'StageName',
operator: '=',
value: 'Closed Won',
literalType: 'STRING',
},
},
},
limit: 150,
};
const composedQuery = composeQuery(soqlQuery, { format: true });
console.log(composedQuery);
Results
SELECT Id, Name, FORMAT(Amount) MyFormattedAmount,
(
SELECT Quantity, ListPrice, PricebookEntry.UnitPrice,
PricebookEntry.Name
FROM OpportunityLineItems
)
FROM Opportunity
WHERE CreatedDate > LAST_N_YEARS:1
AND StageName = 'Closed Won'
LIMIT 150
Composing a partial query
If you need to compose just a part of a query instead of the entire query, you can create an instance of the Compose class directly.
For example, if you just need the "WHERE" clause from a query as a string, you can do the following:
import { Compose, getComposedField, parseQuery } from 'soql-parser-js';
const soql = `SELECT Id FROM Account WHERE Name = 'Foo'`;
const parsedQuery = parseQuery(soql);
const composer = new Compose(parsedQuery, { autoCompose: false });
const whereClause = composer.parseWhereClause(parsedQuery.where);
console.log(whereClause);
}
Format Query
This function is provided as a convenience and just calls parse and compose.
Check out the demo to see the outcome of the various format options.
import { formatQuery } from 'soql-parser-js';
const query = `SELECT Id, Name, AccountNumber, AccountSource, AnnualRevenue, BillingAddress, BillingCity, BillingCountry, BillingGeocodeAccuracy, ShippingStreet, Sic, SicDesc, Site, SystemModstamp, TickerSymbol, Type, Website, (SELECT Id, Name, AccountId, Amount, CampaignId, CloseDate, CreatedById, Type FROM Opportunities), (SELECT Id, Name, AccountNumber, AccountSource, AnnualRevenue, BillingAddress, Website FROM ChildAccounts) FROM Account WHERE Name LIKE 'a%' OR Name LIKE 'b%' OR Name LIKE 'c%'`;
const formattedQuery1 = formatQuery(query);
const formattedQuery2 = formatQuery(query, {
fieldMaxLineLength: 20,
fieldSubqueryParensOnOwnLine: false,
whereClauseOperatorsIndented: true,
});
const formattedQuery3 = formatQuery(query, { fieldSubqueryParensOnOwnLine: true, whereClauseOperatorsIndented: true });
SELECT Id, Name, AccountNumber, AccountSource, AnnualRevenue,
BillingAddress, BillingCity, BillingCountry, BillingGeocodeAccuracy,
ShippingStreet, Sic, SicDesc, Site, SystemModstamp, TickerSymbol, Type,
Website,
(
SELECT Id, Name, AccountId, Amount, CampaignId, CloseDate,
CreatedById, Type
FROM Opportunities
),
(
SELECT Id, Name, AccountNumber, AccountSource, AnnualRevenue,
BillingAddress, Website

)

AccountNumber, AccountSource,
AnnualRevenue, BillingAddress,

(SELECT Id, Name,
AccountId, Amount, CampaignId,
CloseDate, CreatedById, Type
FROM Opportunities),
(SELECT Id, Name,
AccountNumber, AccountSource,
AnnualRevenue, BillingAddress,
Website
FROM ChildAccounts)
FROM Account
WHERE Name LIKE 'a%'
OR Name LIKE 'b%'
OR Name LIKE 'c%'
SELECT Id, Name, AccountNumber, AccountSource, AnnualRevenue,
BillingAddress, BillingCity, BillingCountry, BillingGeocodeAccuracy,
ShippingStreet, Sic, SicDesc, Site, SystemModstamp, TickerSymbol, Type,

Utility Functions
The following utility functions are available:
getField(input: string | ComposeFieldInput)
- Convenience method to construct fields in the correct format. See data model below for the various input types as well as example usage in the Compose examples above.
- returns one of the following data structures:
SoqlModels.FieldFunctionExpression | SoqlModels.Field | SoqlModels.FieldRelationship | SoqlModels.FieldSubquery | SoqlModels.FieldTypeOf
.
isSubquery(query: Query | Subquery)
- Returns
true
if the data passed in is a subquery
getFlattenedFields(query: Query | Subquery | FieldSubquery)
