Returns the Transact-SQL source text of the definition of a specified object.
Transact-SQL syntax conventions
OBJECT_DEFINITION ( object_id )
To view Transact-SQL syntax for SQL Server 2014 and earlier, see Previous versions documentation.
Is the ID of the object to be used. object_id is int, and assumed to represent an object in the current database context.
Returns NULL on error or if a caller does not have permission to view the object.
A user can only view the metadata of securables that the user owns or on which the user has been granted permission. This means that metadata-emitting, built-in functions such as OBJECT_DEFINITION may return NULL if the user does not have any permission on the object. For more information, see Metadata Visibility Configuration.
The SQL Server Database Engine assumes that object_id is in the current database context. The collation of the object definition always matches that of the calling database context.
OBJECT_DEFINITION applies to the following object types:
C = Check constraint
D = Default (constraint or stand-alone)
P = SQL stored procedure
FN = SQL scalar function
R = Rule
RF = Replication filter procedure
TR = SQL trigger (schema-scoped DML trigger, or DDL trigger at either the database or server scope)
IF = SQL inline table-valued function
TF = SQL table-valued function
V = View
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. These permissions are implicitly held by members of the db_owner, db_ddladmin, and db_securityadmin fixed database roles.
A. Returning the source text of a user-defined object
The following example returns the definition of a user-defined trigger,
uAddress, in the
Person schema. The built-in function
OBJECT_ID is used to return the object ID of the trigger to the
USE AdventureWorks2012; GO SELECT OBJECT_DEFINITION (OBJECT_ID(N'Person.uAddress')) AS [Trigger Definition]; GO
B. Returning the source text of a system object
The following example returns the definition of the system stored procedure
USE AdventureWorks2012; GO SELECT OBJECT_DEFINITION (OBJECT_ID(N'sys.sp_columns')) AS [Object Definition]; GO
