复制具体相关代码 具体相关代码如下:
--1、为网站数据库启用SQL Server全文索引
EXEC sp_fulltext_database 'enable'
--2、创建全文目录
--(此处若出错“未安装全文搜索或无法加载某一全文组件”,则可能是未启动或未安装此服务)
EXEC sp_fulltext_catalog 'Ask91Fable', 'create', 'D:\Data2005\Ask_91_Index'
--3、指定要进行全文搜索的表
--(可能出错“...全文搜索键必须是唯一的、不可为空的、单列的索引,并且该索引不是离线的...”)
--(这个表必须有一个唯一索引[主键是可以的],)
EXEC sp_fulltext_table 'Asks', 'create', 'Ask91Fable', 'PK_Ask'--唯一索引名称
--4、向全文目录中添加列
EXEC sp_fulltext_column 'Asks', 'Subject', 'add'
EXEC sp_fulltext_column 'Asks', 'Detail', 'add'
--5、激活全文目录
EXEC sp_fulltext_table 'Asks', 'activate'
--填充
EXEC sp_fulltext_table 'Asks', 'start_full'--完全填充
--EXEC sp_fulltext_table 'Asks', 'start_incremental'--增量填充
--重建(重建之后应该完全填充)
--EXEC sp_fulltext_catalog 'Ask91Fable', 'rebuild'
--调用(100万数据,)
--SELECT TOP 1 * FROM Asks
SELECT ID FROM Asks WhERE Subject LIKE '%NET小结%' OR Detail LIKE '%NET小结%'-- 2分33秒
SELECT ID FROM Asks WhERE CONTAINS (Asks.*,'NET小结')-- 0分40秒
SELECT ID FROM Asks WhERE Subject LIKE '%NET小结%' -- 0分42秒
SELECT ID FROM Asks WhERE CONTAINS (Asks.Subject,'NET小结')-- 0分26秒
