如何在SQL中启用全文检索功能？
--------------------------------------------------------------------------------
全文索引的一个例子，在查询分析器中使用：
use pubs
go
--打开数据库全文索引的支持
execute sp_fulltext_database @#enable@#
go
--建立全文目录ft_titles
execute sp_fulltext_catalog @#ft_titles@#, @#create@#
go
--为titles表建立全文索引数据元，UPKCL_titleidind是主键所建立的唯一索引，可由sp_help titles得知
execute sp_fulltext_table @#titles@#,@#create@#, @#ft_titles@#, @#UPKCL_titleidind@#
go
--设置全文索引列名
exec sp_fulltext_column @#titles@#, @#title@#, @#add@#
go
exec sp_fulltext_column @#titles@#, @#notes@#, @#add@#
go
--建立全文索引
exec sp_fulltext_table @#titles@#, @#activate@#
go
--填充全文索引目录
exec sp_fulltext_catalog @#ft_titles@#, @#start_full@#
go
--使用contains和freetext
select title, notes from titles
where contains(title, @#"computer Cooking"@#)
go
select title, notes from titles
where freetext(title, @#computer Cooking@#)
go
select title, notes from titles
where freetext(title, @#"computer Cooking"@#)
go
select title, notes from titles
where contains(title, @#computer@#)
go
select title, notes from titles
where freetext (*, @#computer@#)
go
