SOQL Parser JS

Description

☀️ This library allows parsing Salesforce SOQL queries using JavaScript or Typescript. Works in the browser and node. ☀️

SOQL Parser JS provides the following capabilities:

1. Parse a SOQL query into a usable data structure.
2. Turn a parsed data structure back into a well formed SOQL query with various format options.
3. Check if a SOQL query is syntactically valid (note: some cases may be structurally valid but not allowed by Salesforce, e.x. invalid field name).

This library is written in Typescript and all type definitions are included with the library for your benefit if you choose to use Typescript or use VSCode's automatic type checking.

⚠️ antlr4 is dependency for this library and is a rather large library (~600 KB) and is required for the parser to function. Consider using dynamic imports to achieve lazy loading.

Usage

Parsing

Parsing a SOQL query can be completed by calling parseQuery(soqlQueryString, options). A Query data structure will be returned;

Typescript / ES6

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));

Results

{
  "fields": [
    {
      "type": "Field",
      "field": "UserId"
    },
    {
      "type": "FieldFunctionExpression",
      "rawValue": "COUNT(Id)",
      "fn": "COUNT",
      "isAggregateFn": true,
      "parameters": ["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"
  }
}

Options

export interface SoqlQueryConfig {
  continueIfErrors?: boolean; // default=false
  logging: boolean; // default=false
}

Composing

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.

📄 Note: Some operators may be converted to upper case (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.

The base query object is shaped like this:

export interface QueryBase {
  fields: FieldType[];
  sObjectAlias?: string;
  where?: WhereClause;
  limit?: number;
  offset?: number;
  groupBy?: GroupByClause;
  having?: HavingClause;
  orderBy?: OrderByClause | OrderByClause[];
  withDataCategory?: WithDataCategoryClause;
  for?: ForClause;
  update?: UpdateClause;
}

The easiest way to build the fields is to call the utility function getComposedField().

Example

This is the query that will be composed programmatically

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

import { composeQuery, getComposedField } from 'soql-parser-js';

const oppLineItemsSubquery = {
  fields: [
    getComposedField('Quantity'),
    getComposedField('ListPrice'),
    getComposedField({
      field: 'UnitPrice',
      relationships: ['PricebookEntry'],
    }),
    getComposedField({
      field: 'Name',
      relationships: ['PricebookEntry'],
    }),
  ],
  relationshipName: 'OpportunityLineItems',
};

const soqlQuery = {
  fields: [
    getComposedField('Id'),
    getComposedField('Name'),
    getComposedField({
      fn: 'FORMAT',
      parameters: 'Amount',
      alias: 'MyFormattedAmount',
    }),
    getComposedField({ 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);

In the example above, we made use of getComposedField(input: string | ComposeFieldInput) to compose the fields. The input expects a string or one of the following data structures listed below. An error will be thrown if the data passed in is not one of the following shapes.

This returns a FieldType object.

export interface ComposeField {
  field: string;
  objectPrefix?: string;
}

export interface ComposeFieldFunction {
  fn: string;
  parameters?: string | string[] | FieldFunctionExpression | FieldFunctionExpression[];
  alias?: string;
}

export interface ComposeFieldRelationship {
  field: string;
  relationships: string[];
  objectPrefix?: string;
}

export interface ComposeFieldSubquery {
  subquery?: Subquery;
}

export interface ComposeFieldTypeof {
  field: string;
  conditions: FieldTypeOfCondition[];
}

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'

}

Checking if a Query is Valid

This will parse a Query to confirm valid syntax, but will not parse into the Query data structure, which will have a small performance gain. This method is faster than parsing the full query.

Options:

export interface ConfigBase {
  logging: boolean; // default=false
}

import { isQueryValid } 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 isValid = isQueryValid(soql);

console.log(isValid);

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, {
  fieldMaxLineLen: 20,
  fieldSubqueryParensOnOwnLine: false,
  whereClauseOperatorsIndented: true,
});
const formattedQuery3 = formatQuery(query, { fieldSubqueryParensOnOwnLine: true, whereClauseOperatorsIndented: true });
