SQL SERVER全文搜索

--在执行该脚本程序之前启动sql server的全文搜索服务，即microsoft search服务
use pubs --打开数据库
go
--检查pubs是否支持全文索引，如果不支持全文索引，则使用sp_fulltext_datebase打开该功能
if (select databaseproperty ('pubs','IsFulltextEnables'))=0
execute sp_fulltext_database 'enable'
--建立全文目录FT_pubs
execute sp_fulltext_catalog 'FT_pubs','create'
--为titles表建立全文索引数据元
execute sp_fulltext_table 'titles','create','FT_pubs','UPKCL_titleidind'
--设置全文索引列名
execute sp_fulltext_column 'titles','title','add'
execute sp_fulltext_column 'titles','notes','add'
--建立全文索引
execute sp_fulltext_table 'titles','activate'
--填充全文索引目录
execute sp_fulltext_catalog 'FT_pubs','start_full'
GO
--检查全文目录填充情况
WHILE FulltextCatalogProperty("FT_pubs','PopulateStatus')<>0
BEGIN
--如果全文目录正处于填充状态，则等待30秒后再检测一次
WAITFOR DELAY ‘0：0：30’
END
--全文目录填充完成后，使用全文目录检索

alter table company add constraint company_cid primary key(cid)
execute sp_fulltext_database 'enable'

execute sp_fulltext_table 'company','create','ft_rh','company_cid'
execute sp_fulltext_column 'company','company','add'
execute sp_fulltext_table 'company','activate'
execute sp_fulltext_catalog 'ft_rh','start_full'
