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 a SQL module definition in this view. For a description of these types, see the `type` column in the [sys.objects](../../relational-databases/system-catalog-views/sys-objects-transact-sql.md) catalog view. For more information, see [Scalar User-Defined Functions for In-Memory OLTP](../../relational-databases/in-memory-oltp/scalar-user-defined-functions-for-in-memory-oltp.md). |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](../../t-sql/functions/object-definition-transact-sql.md) 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 \.

-2 = EXECUTE AS OWNER.| |**uses_native_compilation**|**bit**|**Applies to**: [!INCLUDE[ssSQL14](../../includes/sssql14-md.md)] through [!INCLUDE[ssSQL14](../../includes/sssql14-md.md)].

0 = not natively compiled

1 = is natively compiled

The default value is 0.| |**is_inlineable**|**bit**|**Applies to**: [!INCLUDE[sssql19-md](../../includes/sssql19-md.md)] and later.

Indicates whether the module is inlineable or not. Inlineability is based on the conditions specified [here](../user-defined-functions/scalar-udf-inlining.md#requirements).

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**: [!INCLUDE[sssql19-md](../../includes/sssql19-md.md)] 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](../../relational-databases/system-catalog-views/sys-default-constraints-transact-sql.md) catalog view. The SQL expression for a CHECK constraint, object of type C, is found in the [sys.check_constraints](../../relational-databases/system-catalog-views/sys-check-constraints-transact-sql.md) catalog view. This information is also described in [sys.dm_db_uncontained_entities (Transact-SQL)](../../relational-databases/system-dynamic-management-views/sys-dm-db-uncontained-entities-transact-sql.md). 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](../../t-sql/functions/object-definition-transact-sql.md) 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.
