網(wǎng)站運營seo文章大全提供全面的站長運營經(jīng)驗及seo技術! 如何在sql中啟用全文檢索功能?本文將通過實例向你剖折這個問題。這是一個全文索引的一個例子,首先在查詢分析器中使用:
   use pubs
  go 
  --打開數(shù)據(jù)庫全文索引的支持
  execute sp_fulltext_database 'enable'
 go 
  --建立全文目錄ft_titles
   execute sp_fulltext_catalog 'ft_titles', 'create'
  go 
  --為titles表建立全文索引數(shù)據(jù)元,upkcl_titleidind是主鍵所建立的唯一索引,可由sp_help titles得知
   execute sp_fulltext_table 'titles','create', 'ft_titles', 'upkcl_titleidind'
  go 
  --設置全文索引列名
   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 
  --填充全文索引目錄
   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
