Returns information about full-text catalog properties.
Returns NULL on error or if a caller does not have permission to view the object.
In SQL Server 2008, 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 FULLTEXTCATALOGPROPERTY may return NULL if the user does not have any permission on the object. For more information, see Metadata Visibility Configuration and Troubleshooting Metadata Visibility.
FULLTEXTCATALOGPROPERTY ('catalog_name' ,'IndexSize') looks at only fragments with status 4 or 6 as shown in sys.fulltext_index_fragments. These fragments are part of the logical index. Therefore, the IndexSize property returns only the logical index size. During an index merge, however, the actual index size might be double its logical size. To find the actual size that is being consumed by a full-text index during a merge, use the sp_spaceused system stored procedure. That procedure looks at all fragments associated with a full-text index.
It is important that applications do not wait in a tight loop, checking for the PopulateStatus property to become idle (indicating that population has completed) because this takes CPU cycles away from the database and full-text search processes, and causes timeouts. In addition, it is usually a better option to check the corresponding PopulateStatus property at the table level, TableFullTextPopulateStatus in the OBJECTPROPERTYEX system function. This and other new full-text properties in OBJECTPROPERTYEX provide more granular information about full-text indexing tables. For more information, see OBJECTPROPERTYEX (Transact-SQL).
The following example returns the number of full-text indexed items in a full-text catalog named Cat_Desc.
USE AdventureWorks2008R2; GO SELECT fulltextcatalogproperty('Cat_Desc', 'ItemCount'); GO
