Remarks

sp_helptext displays the definition that is used to create an object in multiple rows. Each row contains 255 characters of the Transact-SQL definition. The definition resides in the definition column in the sys.sql_modules catalog view.

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

The following example displays the definition of the trigger dEmployee in the AdventureWorks2022 database.

USE AdventureWorks2022;

EXEC sp_helptext 'HumanResources.dEmployee';
GO

B. Display the definition of a computed column

The following example displays the definition of the computed column TotalDue on the SalesOrderHeader table in the AdventureWorks2022 database.
