soql-parser-js

Description

This library allows parsing and composing SOQL queries from Salesforce using JavaScript or Typescript.

Available Features:

1. Parse SOQL queries into a common Query data structure.
2. Deterministically compose a Query data structure back into a SOQL query string.
3. Validate a query to check if the syntax is valid.
   1. 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.

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); // SELECT Id FROM Account WHERE Id = 'FOO'

isQueryValid('SELECT Id, Foo FROM Baz'); // true
isQueryValid('SELECT Id Foo FROM Baz'); // false

Utility Functions

General Utility

Many of hte utility functions are provided to easily determine the shape of specific data since there are many variations. If you are using Typescript in strict mode, you can use these to narrow types with if statements.

Function	Description	Arguments
hasAlias	Returns true if the field passed in has the alias property.	input: `string
getField	Convenience method to construct fields in the correct format when using composeQuery(). Look in the data models section below for the structure of ComposeFieldInput.	input: `string
getFlattenedFields	Flatten a Salesforce record based on the parsed SOQL Query. this is useful if you have relationships in your query and want to show the results in a table, using . dot notation for the relationship field headings.	soql: `Query
isSubquery	Returns true if the data passed in is a subquery.	query: `Query
isFieldSubquery	Returns true if the data passed in is a FieldSubquery.	value: any
isWhereClauseWithRightCondition	Returns true if the value passed in is a WhereClause with an operator and right property	value: WhereClause

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';
// var soqlParserJs = require('soql-parser-js'); // node's require format - usage: soqlParserJs.parseQuery()

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));

{
  "fields": [
    {
      "type": "Field",
      "field": "UserId"
    },
    {
      "type": "FieldFunctionExpression",
      "functionName": "COUNT",
      "parameters": ["Id"],
      "isAggregateFn": true,
      "rawValue": "COUNT(Id)"
    }
  ],
  "sObject": "LoginHistory",
  "where": {
    "left": {
      "field": "LoginTime",
      "operator": ">",
      "value": "2010-09-20T22:16:30.000Z",
      "literalType": "DATETIME"
    },
    "operator": "AND",
    "right": {
      "left": {
        "field": "LoginTime",
        "operator": "<",
        "value": "2010-09-21T22:16:30.000Z",
        "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';

// Build a subquery
const oppLineItemsSubquery = {
  fields: [
    getField('Quantity'),
    getField('ListPrice'),
    getField({
      field: 'UnitPrice',
      relationships: ['PricebookEntry'],
    }),
    getField({
      field: 'Name',
      relationships: ['PricebookEntry'],
    }),
  ],
  relationshipName: 'OpportunityLineItems',
};

// build the main query and add the subquery as a field
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 is optional, but if set to STRING and our value is not already wrapped in "'", they will be added
        // All other literalType values are ignored when composing a query
        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);

// Results of Parsed Query:
  // const parsedQuery = {
  //   fields: [
  //     {
  //       type: 'Field',
  //       field: 'Id',
  //     },
  //   ],
  //   sObject: 'Account',
  //   where: {
  //     left: {
  //       field: 'Name',
  //       operator: '=',
  //       value: "'Foo'",
  //       literalType: 'STRING',
  //     },
  //   },
  // };

  // Create a new instance of the compose class and set the autoCompose to false to avoid composing the entire query
  const composer = new Compose(parsedQuery, { autoCompose: false });


  const whereClause = composer.parseWhereClause(parsedQuery.where);

  console.log(whereClause);
  // Name = 'Foo'
}

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 });

Changelog

4.1.1

June 6, 2021

#153 - A new parser option has been added named ignoreParseErrors, which will remove invalid parts of a query if there are parsing errors.

The general structure of the query must be valid and the SELECT and WHERE clauses must both be valid, but any other clause may be removed from the parsed output if there are errors parsing the query and ignoreParseErrors is set to true.

This option has been added to the documentation application.
