--但只已知一个字符串,去查询整个数据库内有那些表里面包含这个字符串,用游标可以实现了这个需求,但是我想求一个能查询数据库里面所有nvarchar、varchar并且能分页的存储过程:
create proc Full_Search(@string varchar(50))asbegin declare @tbname varchar(50) declare tbroy cursor for select name from sysobjects where xtype='u' --第一个游标遍历所有的表 open tbroyfetch next from tbroy into @tbnamewhile @@fetch_status=0begin declare @colname varchar(50) declare colroy cursor for select name from syscolumns where id=object_id(@tbname) and xtype in ( select xtype from systypes where name in ('varchar','nvarchar','char','nchar') --数据类型为字符型的字段 ) --第二个游标是第一个游标的嵌套游标,遍历某个表的所有字段 open colroy fetch next from colroy into @colname while @@fetch_status=0 begin declare @sql nvarchar(1000),@j int select @sql='select @i=count(1) from ' +@tbname +' where '+ @colname+' like '+'''%'+@string+'%''' exec sp_executesql @sql,N'@i int output',@i=@j output --输出满足条件表的记录数 if @j>0 exec('select distinct '+@colname+' from ' +@tbname +' where '+ @colname+' like '+'''%'+@string+'%''') fetch next from colroy into @colname end close colroy deallocate colroy fetch next from tbroy into @tbnameendclose tbroydeallocate tbroyend exec Full_Search '市场' drop proc Full_Search
