sys.sql_modules (Transact-SQL)

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW) SQL analytics endpoint in Microsoft Fabric Warehouse in Microsoft Fabric

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 (15.x) 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 user-defined functions (UDFs), the value will be 1 if the UDF is inlineable, and 0 otherwise. It always contains a value of 1 for inline table-valued functions (TVFs), and 0 for all other module types.
inline_type bit Applies to: SQL Server 2019 (15.x) and later.

Indicates whether inlining is turned on for the module currently.

0 = inlining is turned off

1 = inlining is turned on.

For scalar user-defined functions (UDFs), the value will be 1 if inlining is turned on (explicitly or implicitly). The value will always be 1 for inline table-valued functions (TVFs), and 0 for other module types.

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).

Renaming a stored procedure, function, view, or trigger won't change the name of the corresponding object in the definition column of the sys.sql_modules catalog view or the definition returned by the OBJECT_DEFINITION built-in function. For this reason, we recommend that sp_rename not be used to rename these object types. Instead, drop and re-create the object with its new name. Learn more in sp_rename (Transact-SQL).

Permissions

The visibility of the metadata in catalog views is limited to securables that a user either owns, or on which the user was granted some permission. For more information, see Metadata Visibility Configuration.

Examples

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

SELECT 
          sm.object_id
        , ss.[name] as [schema]
        , o.[name] 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  
JOIN sys.schemas AS ss
    ON o.schema_id = ss.schema_id  
ORDER BY 
      o.[type]
    , ss.[name]
    , o.[name];
