    Property Description

    AccentSensitivity

    Accent-sensitivity setting.

    0 = Accent insensitive

    1 = Accent sensitive

    IndexSize

    Size of the full-text catalog in megabytes (MB).

    Size, in bytes, of the combined set of error logs associated with a Microsoft Search Service full-text catalog.

    MergeStatus

    Master merge is in progress.

    0 = master merge not in progress

    PopulateCompletionAge

    The difference in seconds between the completion of the last full-text index population and 01/01/1990 00:00:00.

    Only updated for full and incremental crawls. Returns 0 if no population has occurred.

    PopulateStatus

    0 = Idle

int

Exceptions

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

In SQL Server 2005, 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.

Remarks

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 time outs. 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).

Examples

The following example returns the number of full-text indexed items in a full-text catalog named Cat_Desc.

USE AdventureWorks;
GO
SELECT fulltextcatalogproperty('Cat_Desc', 'ItemCount');
GO
