# sys.sql_modules (Transact-SQL)
[!INCLUDE[tsql-appliesto-ss2008-all_md](../../includes/tsql-appliesto-ss2008-all-md.md)]

  Returns a row for each object that is an SQL language-defined module in [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)], 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](../../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.<br /><br /> NULL = Encrypted.|  
|**uses_ansi_nulls**|**bit**|Module was created with SET ANSI_NULLS ON.<br /><br /> 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.<br /><br /> 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.<br /><br /> NULL by default or if EXECUTE AS CALLER.<br /><br /> ID of the specified principal if EXECUTE AS SELF or EXECUTE AS \<principal>.<br /><br /> -2 = EXECUTE AS OWNER.|  
|**uses_native_compilation**|**bit**|**Applies to**: [!INCLUDE[ssSQL14](../../includes/sssql14-md.md)] through [!INCLUDE[ssSQL14](../../includes/sssql14-md.md)].<br /><br /> 0 = not natively compiled<br /><br /> 1 = is natively compiled<br /><br /> The default value is 0.|  
  
## 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 &#40;Transact-SQL&#41;](../../relational-databases/system-dynamic-management-views/sys-dm-db-uncontained-entities-transact-sql.md).  
  
## Permissions  
 [!INCLUDE[ssCatViewPerm](../../includes/sscatviewperm-md.md)] For more information, see [Metadata Visibility Configuration](../../relational-databases/security/metadata-visibility-configuration.md).  
  
## 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  
```
