Subform is a data section embedded in the primary form to collect details related to the parent record. It  helps in maintaining multiple records under a single parent record. These subform records cannot be fetched via the parent module in the Query API. Since subforms are treated as individual modules, you should state their API names to access their records or fields. Consider a manufacturing company, Zylker, which uses Zoho CRM for effective maintenance of customer relationships. The suggestions and feedback from each of their clients are tracked with the help of a subform called Client Review in the Accounts module.

Consider a manufacturing company, Zylker, which uses Zoho CRM for effective maintenance of customer relationship. The suggestions and feedback of each of their clients is tracked with the help of a subform called Client Review in the Accounts module. 

Now the Manager wants to fetch the suggestions from all the Accounts. Let us see how he can achieve this using COQL API. 

Step 1: Make a GET Modules metadata API call to get the api_name of the subform.

Step 2: Using the api_name of the subform, make a GET Fields metadata API call to get the api_name of the fields in the subform. 

Step 3: Use the api_name of subform and subform fields to construct a query. 

We can filter the records that have subform fields in them using COQL. Consider the example of the above manufacturing company, Zylker. The manager wants to fetch the details of those records in the Accounts modules that have Client Review details. This can be achieved by the following COQL query.
