sys.dm_fts_active_catalogs (Transact-SQL)

Returns information on the full-text catalogs that have some population activity in progress on the server.

Note

The following columns will be removed in a future version of Microsoft SQL Server: is_paused, previous_status, previous_status_description, row_count_in_thousands, status, status_description, and worker_count. Avoid using these columns in new development work, and plan to modify applications that currently use any of them.

status	int	Current state of the full-text catalog. One of the following: 0 = Initializing 1 = Ready 2 = Paused 3 = Temporary error 4 = Remount needed 5 = Shutdown 6 = Quiesced for backup 7 = Backup is done through catalog 8 = Catalog is corrupt
status_description	nvarchar(120)	Description of current state of the active full-text catalog.

previous_status_description	nvarchar(120)	Description of previous state of the active full-text catalog.
worker_count	int	Number of threads currently working on this full-text catalog.
active_fts_index_count	int	Number of full-text indexes that are being populated.
auto_population_count	int	Number of tables with an auto population in progress for this full-text catalog.
manual_population_count	int	Number of tables with manual population in progress for this full-text catalog.
full_incremental_population_count	int	Number of tables with a full or incremental population in progress for this full-text catalog.
row_count_in_thousands	int	Estimated number of rows (in thousands) in all full-text indexes in this full-text catalog.

Examples

The following example returns information about the active full-text catalogs on the current database.

SELECT catalog.name, catalog.is_importing, catalog.auto_population_count, OBJECT_NAME(population.table_id) AS table_name, population.population_type_description, population.is_clustered_index_scan, population.status_description, population.completion_type_description, population.queued_population_type_description, population.start_time, population.range_count 
FROM sys.dm_fts_active_catalogs catalog 
CROSS JOIN sys.dm_fts_index_population population 
WHERE catalog.database_id = population.database_id 
AND catalog.catalog_id = population.catalog_id 
AND catalog.database_id = (SELECT dbid FROM sys.sysdatabases WHERE name = DB_NAME());
