sp_fulltext_column [ @tabname= ] 'qualified_table_name' , 
     [ @colname= ] 'column_name' , 
     [ @action= ] 'action' 
     [ , [ @language= ] 'language_term' ] 
     [ , [ @type_colname= ] 'type_column_name' ]

Arguments

• [ @tabname= ] 'qualified_table_name'
  Is a one- or two-part table name. The table must exist in the current database. The table must have a full-text index. qualified_table_name is nvarchar(517), with no default value.

• [ @colname= ] 'column_name'
  Is the name of a column in qualified_table_name. The column must be either a character, varbinary(max) or image column and cannot be a computed column. column_name is sysname, with no default.

  [!UWAGA]

  SQL Server can create full-text indexes of text data stored in columns that are of varbinary(max) or image data type. Images and pictures are not indexed.

• [ @action= ] 'action'
  Is the action to be performed. action is varchar(20), with no default value, and can be one of the following values.

  Value	Description
  add	Adds column_name of qualified_table_name to the table's inactive full-text index. This action enables the column for full-text indexing.
  drop	Removes column_name of qualified_table_name from the table's inactive full-text index.

• [ @language= ] 'language_term'
  Is the language of the data stored in the column. For a list of languages included in SQL Server, see sys.fulltext_languages (Transact-SQL).

  [!UWAGA]

  Use 'Neutral' when a column contains data in multiple languages or in an unsupported language. The default is specified by the configuration option 'default full-text language'.

• [ @type_colname = ] 'type_column_name'
  Is the name of a column in qualified_table_name that holds the document type of column_name. This column must be char, nchar, varchar, or nvarchar. It is only used when the data type of column_name is of type varbinary(max) or image. type_column_name is sysname, with no default.

Return Code Values

0 (success) or 1 (failure)

Result Sets

None

Uwagi

If the full-text index is active, any ongoing population is stopped. Furthermore, if a table with an active full-text index has change tracking enabled, SQL Server ensures that the index is current. For example, SQL Server stops any current population on the table, drops the existing index, and starts a new population.

If change tracking is on and columns need to be added or dropped from the full-text index while preserving the index, the table should be deactivated, and the required columns should be added or dropped. These actions freeze the index. The table can be activated later when starting a population is practical.

Permissions

User must be a member of the db_ddladmin fixed database role, or a member of the db_owner fixed database role, or the owner of the table.

Examples

The following example adds the DocumentSummary column from the Document table to the full-text index of the table.

USE AdventureWorks;
GO
EXEC sp_fulltext_column 'Production.Document', DocumentSummary, 'add';
GO

The following example assumes you created a full-text index on a table named spanishTbl. To add the spanishCol column to the full-text index, execute the following stored procedure:

EXEC sp_fulltext_column 'spanishTbl', 'spanishCol', 'add', 0xC0A;
GO

When you run this query:

SELECT * 
FROM spanishTbl 
WHERE CONTAINS(spanishCol, 'formsof(inflectional, trabajar)')

The result set would include rows with different forms of trabajar (to work), such as trabajo, trabajamos, and trabajan.

[!UWAGA]

All columns listed in a single full-text query function clause must use the same language.
