- wordbreaker
- filter
- protocol handler
- fullpath
If a full path is specified, param must also be specified with the full path to the component DLL, or an error message is returned.

For information about full-text search components, see Full-Text Search Architecture and Configuring Full-Text Linguistic Components.
[ @param= ] param
Depending on component type, this is one of the following: a locale identifier (LCID), the file extension with "." prefix, the full component name of the protocol handler, or the full path to the component DLL.

Return Code Values

0 (success) or (1) failure

Result Sets

The following result set is returned for the system components.

Column name	Data type	Description
componenttype	sysname	Type of component. One of the following: filter protocol handler wordbreaker
componentname	sysname	Name of the component.
clsid	uniqueidentifier	Class identifier of the component.
fullpath	nvarchar(256)	Path to the location of the component. NULL = Caller not a member of serveradmin fixed server role.
version	nvarchar(30)	Version of the component.
manufacturer	sysname	Name of the manufacturer of the component.

The following result set is returned only if one or more than one full-text catalog exists that uses component_type.

Column name	Data type	Description
dbid	int	ID of the database.
ftcatid	int	ID of the full-text catalog.

Permissions

Requires membership in the public role; however, users can only see information about the full-text catalogs for which they have VIEW DEFINITION permission. Only members of the serveradmin fixed server role can see values in the fullpath column.

Remarks

This method is of particular importance when preparing for an upgrade. Execute the stored procedure within a particular database, and use the output to determine whether a particular catalog will be impacted by the upgrade.

Examples

A. Listing all full-text system components

The following example lists all of the full-text system components that have been registered on the server instance.

EXEC sp_help_fulltext_system_components 'all';
GO

B. Listing word breakers

The following example lists all the word breakers registered on the service instance.

EXEC sp_help_fulltext_system_components 'wordbreaker';
GO

C. Determining whether a specific word breaker is registered

The following example will list the word breaker for the Turkish language (LCID = 1055) if it has been installed on the system and registered on the service instance. This example specifies the parameter names, @component_type and @param.

EXEC sp_help_fulltext_system_components @component_type = 'wordbreaker', @param = 1055;
GO

By default, this word breaker is not installed, so the result set is empty.

D. Determining whether a specific filter has been registered

The following example lists the filter for the .xdoc component if it has been manually installed on the system and registered on the server instance.

EXEC sp_help_fulltext_system_components 'filter', '.xdoc';
GO

By default, this filter is not installed, so the result set is empty.

E. Listing a specific .dll file

The following example lists a specific .ddl file, nlhtml.dll, which is installed by default.

EXEC sp_help_fulltext_system_components 'fullpath', 
   'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Binn\nlhtml.dll';
GO
