The sp_fulltext_catalog system stored procedure in SQL Server is used for managing full-text catalogs. It provides various functionalities, such as creating, dropping, or updating full-text catalogs, retrieving information about a catalog, and controlling its status.
Here's a breakdown of how to use the sp_fulltext_catalog procedure along with some common tasks:
Syntax
The basic syntax of the sp_fulltext_catalog stored procedure is as follows:
EXEC sp_fulltext_catalog @catalog_name = 'catalog_name', @action = 'action'
Parameters
- @catalog_name: The name of the full-text catalog you want to manage.
- @action: Specifies the action to take. Possible values include:
- 'create': To create a new full-text catalog.
- 'drop': To drop an existing full-text catalog.
- 'start_full': To start a full population of the catalog.
- 'start_delta': To start a delta population of the catalog.
- 'stop': To stop any ongoing population.
- 'status': To retrieve the status of the catalog.
Examples

To create a new full-text catalog, you can use this command:
EXEC sp_fulltext_catalog 'MyFullTextCatalog', 'create';
2. Drop a Full-Text Catalog
To drop an existing full-text catalog:
EXEC sp_fulltext_catalog 'MyFullTextCatalog', 'drop';
3. Start Full Population
To start a full population on an existing catalog:
EXEC sp_fulltext_catalog 'MyFullTextCatalog', 'start_full';
4. Start Delta Population
To start a delta population (updating only recently modified data):
EXEC sp_fulltext_catalog 'MyFullTextCatalog', 'start_delta';
5. Stop Population
To stop ongoing population tasks for the catalog:
EXEC sp_fulltext_catalog 'MyFullTextCatalog', 'stop';
6. Get Catalog Status

Additional Considerations
- Make sure that the full-text service is installed and configured properly in your SQL Server instance.

- You can use the sys.fulltext_catalogs system view to get information about existing full-text catalogs.
Conclusion
The sp_fulltext_catalog stored procedure is a powerful tool for managing full-text catalogs in SQL Server. By understanding the parameters and available actions, you can effectively create, manage, and monitor full-text catalogs and their populations as required by your applications.
