COQL (CRM Object Query Language) is Zoho CRM’s SQL-like query language that allows developers to retrieve CRM data using structured SELECT queries. It supports filtering with WHERE clauses, sorting, field selection, and joins across related modules, making it a powerful tool for fetching precisely the data needed in Custom Functions, API integrations, and reports.

COQL Syntax Basics

COQL queries follow SQL syntax: SELECT field1, field2 FROM Deals WHERE Stage = 'Proposal Sent' AND Amount > 100000 ORDER BY Created_Time DESC LIMIT 10. Queries are executed via the Zoho CRM REST API endpoint or within Deluge using zoho.crm.searchRecords() with the COQL parameter.

COQL supports: basic field comparisons, IN and NOT IN operators, LIKE for pattern matching, IS NULL and IS NOT NULL, joins across related modules (up to 2 levels), and aggregate functions like COUNT, SUM, MIN, MAX.

COQL vs searchRecords API

The standard searchRecords API supports simple criteria-based filtering but is limited in flexibility. COQL offers full SQL-style querying with multi-field conditions, sorting, field selection, and cross-module joins. For any complex data retrieval in Deluge scripts or external integrations, COQL is the preferred approach.

Industry Example

Analytics Integration: A Zoho Analytics custom connector uses COQL to pull deal data for the current quarter: SELECT Deal_Name, Account_Name, Amount, Stage, Owner FROM Deals WHERE Closing_Date >= '2026-04-01' AND Stage != 'Closed Lost'. The COQL query returns exactly the fields needed for the analytics dashboard, avoiding the need to fetch all deal fields and filter in the receiving application.
