OBJECTPROPERTYEX (Transact-SQL)

  • Άρθρο

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 information about schema-scoped objects in the current database. For a list of these objects, see sys.objects (Transact-SQL). OBJECTPROPERTYEX cannot be used for objects that are not schema-scoped, such as data definition language (DDL) triggers and event notifications.

Transact-SQL syntax conventions

Syntax

OBJECTPROPERTYEX ( id , property )

Arguments

id
Is an expression that represents the ID of the object in the current database. id is int and is assumed to be a schema-scoped object in the current database context.

property
Is an expression that contains the information to be returned for the object specified by id. The return type is sql_variant. The following table shows the base data type for each property value.

Note

Unless noted otherwise, NULL is returned when property is not a valid property name, id is not a valid object ID, id is an unsupported object type for the specified property, or the caller does not have permission to view the object's metadata.

Property name Object type Description and values returned
BaseType Any schema-scoped object Identifies the base type of the object. When the specified object is a SYNONYM, the base type of the underlying object is returned.

Return Types

sql_variant

Exceptions

Returns NULL on error or if a caller does not have permission to view the object.

A user can only view the metadata of securables that the user owns or on which the user has been granted permission. This means that metadata-emitting, built-in functions such as OBJECTPROPERTYEX may return NULL if the user does not have any permission on the object. For more information, see Metadata Visibility Configuration.

Remarks

The Database Engine assumes that object_id is in the current database context. A query that references an object_id in another database will return NULL or incorrect results. For example, in the following query the current database context is the master database. The Database Engine will try to return the property value for the specified object_id in that database instead of the database that is specified in the query. The query returns incorrect results because the view vEmployee is not in the master database.

USE master;  
GO  
SELECT OBJECTPROPERTYEX(OBJECT_ID(N'AdventureWorks2022.HumanResources.vEmployee'), 'IsView');  
GO

OBJECTPROPERTYEX(view_id, 'IsIndexable') may consume significant computer resources because evaluation of IsIndexable property requires the parsing of view definition, normalization, and partial optimization. Although the IsIndexable property identifies tables or views that can be indexed, the actual creation of the index still might fail if certain index key requirements are not met. For more information, see CREATE INDEX (Transact-SQL).

OBJECTPROPERTYEX (table_id, 'TableHasActiveFulltextIndex') will return a value of 1 (true) when at least one column of a table is added for indexing. Full-text indexing becomes active for population as soon as the first column is added for indexing.

Restrictions on metadata visibility are applied to the result set. For more information, see Metadata Visibility Configuration.

Examples

A. Finding the base type of an object

The following example creates a SYNONYM MyEmployeeTable for the Employee table in the AdventureWorks2022 database and then returns the base type of the SYNONYM.

USE AdventureWorks2022;  
GO  
CREATE SYNONYM MyEmployeeTable FOR HumanResources.Employee;  
GO  
SELECT OBJECTPROPERTYEX ( object_id(N'MyEmployeeTable'), N'BaseType')AS [Base Type];  
GO

The result set shows that the base type of the underlying object, the Employee table, is a user table.

Base Type 
--------  
U

B. Returning a property value

The following example returns the number of UPDATE triggers on the specified table.

USE AdventureWorks2022;  
GO  
SELECT OBJECTPROPERTYEX(OBJECT_ID(N'HumanResources.Employee'), N'TABLEUPDATETRIGGERCOUNT');  
GO

C. Finding tables that have a FOREIGN KEY constraint

The following example uses the TableHasForeignKey property to return all the tables that have a FOREIGN KEY constraint.

USE AdventureWorks2022;  
GO  
SELECT name, object_id, schema_id, type_desc  
FROM sys.objects   
WHERE OBJECTPROPERTYEX(object_id, N'TableHasForeignKey') = 1  
ORDER BY name;  
GO

Examples: Azure Synapse Analytics and Analytics Platform System (PDW)

D: Finding the base type of an object

The following example returns the base type of dbo.DimReseller object.

-- Uses AdventureWorks  
  
SELECT OBJECTPROPERTYEX ( object_id(N'dbo.DimReseller'), N'BaseType')AS BaseType;

The result set shows that the base type of the underlying object, the dbo.DimReseller table, is a user table.

BaseType   
--------   
U
