Note

The system stored procedure sp_helptext isn't supported in Azure Synapse Analytics. Instead, use OBJECT_DEFINITION system function or sys.sql_modules object catalog view for equivalent results.

Permissions

Requires membership in the public role. System object definitions are publicly visible. The definition of user objects is visible to the object owner or grantees that have any one of the following permissions: ALTER, CONTROL, TAKE OWNERSHIP, or VIEW DEFINITION.

Examples

A. Display the definition of a trigger
