sys.dm_fts_active_catalogs (Transact-SQL)
Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance
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.

memory_address | varbinary(8) | Address of memory buffers allocated for the population activity related to this full-text catalog. |
name | nvarchar(128) | Name of the active full-text catalog. |
is_paused | bit | Indicates whether the population of the active full-text catalog has been paused. |
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 | int | Previous 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 |
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. |
is_importing | bit | Indicates whether the full-text catalog is being imported: 1 = The catalog is being imported. 2 = The catalog is not being imported. |

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());
