复制代码 代码如下:
–1、为数据库启用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
