CREATE FULLTEXT CATALOG (Transact-SQL)

Artykuł
02/13/2015

Creates a full-text catalog for a database. One full-text catalog can have several full-text indexes, but a full-text index can only be part of one full-text catalog. Each database can contain zero or more full-text catalogs.

You cannot create full-text catalogs in the master, model, or tempdb databases.

Ważne:
Beginning with SQL Server 2008, a full-text catalog is a virtual object and does not belong to any filegroup. A full-text catalog is a logical concept that refers to a group of full-text indexes.

CREATE FULLTEXT CATALOG catalog_name

     [IN PATH 'rootpath']

<catalog_option>::=
     ACCENT_SENSITIVITY = {ON|OFF}

Arguments

catalog_name
Is the name of the new catalog. The catalog name must be unique among all catalog names in the current database. Also, the name of the file that corresponds to the full-text catalog (see ON FILEGROUP) must be unique among all files in the database. If the name of the catalog is already used for another catalog in the database, SQL Server returns an error.

The length of the catalog name cannot exceed 120 characters.
ON FILEGROUP filegroup
Beginning with SQL Server 2008, this clause has no effect.
IN PATH 'rootpath'

[!UWAGA]

This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

Beginning with SQL Server 2008, this clause has no effect.
ACCENT_SENSITIVITY = {ON|OFF}
Specifies that the catalog is accent sensitive or accent insensitive for full-text indexing. When this property is changed, the index must be rebuilt. The default is to use the accent-sensitivity specified in the database collation. To display the database collation, use the sys.databases catalog view.

To determine the current accent-sensitivity property setting of a full-text catalog, use the FULLTEXTCATALOGPROPERTY function with the accentsensitivity property value against catalog_name. If the value returned is '1', the full-text catalog is accent sensitive; if the value is '0', the catalog is not accent-sensitive.
AS DEFAULT
Specifies that the catalog is the default catalog. When full-text indexes are created without a full-text catalog explicitly specified, the default catalog is used. If an existing full-text catalog is already marked AS DEFAULT, setting this new catalog AS DEFAULT will make this catalog the default full-text catalog.
AUTHORIZATION owner_name
Sets the owner of the full-text catalog to the name of a database user or role. If owner_name is a role, the role must be the name of a role that the current user is a member of, or the user running the statement must be the database owner or system administrator.

If owner_name is a user name, the user name must be one of the following:
- The name of the user running the statement.
- The name of a user that the user executing the command has impersonate permissions for.
- Or, the user executing the command must be the database owner or system administrator.
owner_name must also be granted TAKE OWNERSHIP permission on the specified full-text catalog.

Uwagi

Full-text catalog IDs start at 00005 and are incremented by one for each new catalog created.

Permissions

User must have CREATE FULLTEXT CATALOG permission on the database, or be a member of the db_owner, or db_ddladmin fixed database roles.

Examples

The following example creates a full-text catalog and also a full-text index.

USE AdventureWorks;
GO
CREATE FULLTEXT CATALOG ftCatalog AS DEFAULT;
GO
CREATE FULLTEXT INDEX ON HumanResources.JobCandidate(Resume) KEY INDEX PK_JobCandidate_JobCandidateID;
GO
