Creating SObject Dynamically by Using Id

By | November 8, 2016

While working on one of our projects, we faced a challenge where we were supposed to create the object, already existing in the database, dynamically from just an “Id”. We had no information other than the Id field of the record. We can use the functions of SObjectType class to create the instance of a SObject (any Standard or Custom object in the Salesforce) dynamically.

Please find below screenshots for the syntax to create the record dynamically:

You will see in the above code that we have written one method which accepts the first argument as the Id of the record to be updated, the second argument is the string argument that contains the name of the field to be updated, and the third argument being the object type which holds the new value for the field. Within this function, we can use the syntax for dynamic record creation based on Id alone. Once we get the record using the SObjectType, we can populate the field based on the values sent and update the record accordingly into the database. Here is the output of the above code:

This is one of the ways how you can get the reference of an already existing record for any SObject dynamically by simply using its Id and perform desired operations on it.
