sys.sql_modules (Transact-SQL)

[!INCLUDEtsql-appliesto-ss2008-all-md]

Returns a row for each object that is an SQL language-defined module in [!INCLUDEssNoVersion], including natively compiled scalar user-defined function. Objects of type P, RF, V, TR, FN, IF, TF, and R have an associated SQL module. Stand-alone defaults, objects of type D, also have an SQL module definition in this view. For a description of these types, see the type column in the sys.objects catalog view.

For more information, see Scalar User-Defined Functions for In-Memory OLTP.

Column name	Data type	Description
object_id	int	ID of the object of the containing object. Is unique within a database.
definition	nvarchar(max)	SQL text that defines this module. NULL = Encrypted.
uses_ansi_nulls	bit	Module was created with SET ANSI_NULLS ON. Will always be = 0 for rules and defaults.
uses_quoted_identifier	bit	Module was created with SET QUOTED_IDENTIFIER ON.
is_schema_bound	bit	Module was created with SCHEMABINDING option. Always contains a value of 1 for natively compiled stored procedures.
uses_database_collation	bit	1 = Schema-bound module definition depends on the default-collation of the database for correct evaluation; otherwise, 0. Such a dependency prevents changing the database's default collation.
is_recompiled	bit	Procedure was created WITH RECOMPILE option.
null_on_null_input	bit	Module was declared to produce a NULL output on any NULL input.
execute_as_principal_id	Int	ID of the EXECUTE AS database principal. NULL by default or if EXECUTE AS CALLER. ID of the specified principal if EXECUTE AS SELF or EXECUTE AS <principal>. -2 = EXECUTE AS OWNER.
uses_native_compilation	bit	Applies to: [!INCLUDEssSQL14] through [!INCLUDEssSQL14]. 0 = not natively compiled 1 = is natively compiled The default value is 0.

Remarks

The SQL expression for a DEFAULT constraint, object of type D, is found in the sys.default_constraints catalog view. The SQL expression for a CHECK constraint, object of type C, is found in the sys.check_constraints catalog view.

This information is also described in sys.dm_db_uncontained_entities (Transact-SQL).

Examples

The following example returns the name, type, and definition of each module in the current database.

SELECT sm.object_id, OBJECT_NAME(sm.object_id) AS object_name, o.type, o.type_desc, sm.definition  
FROM sys.sql_modules AS sm  
JOIN sys.objects AS o ON sm.object_id = o.object_id  
ORDER BY o.type;  
GO
