Returns a row for each object that is an SQL language-defined module in SQL Server, 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. This value can also be obtained using the OBJECT_DEFINITION built-in function.
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: SQL Server 2014 (12.x) through SQL Server 2014 (12.x).
0 = not natively compiled
1 = is natively compiled
The default value is 0.
|is_inlineable||bit||Applies to: SQL Server 2019 preview and later.
Indicates whether the module is inlineable or not. Inlineability is based on the conditions specified here.
0 = not inlineable
1 = is inlineable.
For scalar UDFs, the value will be 1 if the UDF is inlineable, and 0 otherwise. It always contains a value of 1 for inline TVFs, and 0 for all other module types.
|inline_type||bit||Applies to: SQL Server 2019 preview and later.
Indicates whether inlining is turned on for the module currently.
0 = inlining is turned off
1 = inlining is turned on.
For scalar UDFs, the value will be 1 if inlining is turned on (explicitly or implicitly). The value will always be 1 for inline TVFs, and 0 for other module types.
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).
The visibility of the metadata in catalog views is limited to securables that a user either owns or on which the user has been granted some permission. For more information, see Metadata Visibility Configuration.
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
