可以直接创建sql语句:
CREATE TABLE qResults (tName nvarchar(370), cname nvarchar(3630),[count] int) declare @tname nvarchar(200)
declare @cname nvarchar(200) declare @countOut nvarchar(200)
declare @sql nvarchar(max)
declare c_search cursor for
select t.name,c.name from sysobjects t inner join syscolumns c on t.id=c.id where t.type='u' and c.xtype in(56,167,175,231,239) order by t.name --xtype 这个地方限制类型为int varchar char nvarchar nchar 五种类型
open c_search
fetch next from c_search into @tname,@cname
while @@FETCH_STATUS=0
begin set @sql=N'select @countx=COUNT(*) from '+@tname +' where [' +@cname +'] =''44'' ' print @sql
EXECUTE sp_executesql @sql,N'@countx nvarchar(200) out ', @countx=@countOUT OUT insert into qResults values (@tname,@cname,@countOUT) fetch next from c_search into @tname,@cname
end
select tName 'Table',cname 'Field' from qResults where [count]>0 order by tname
close c_search
deallocate c_search drop table qResults
或者先创建存储过程:
ALTER proc Full_Search(@string varchar(50))
as
begin 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 tbroy
fetch next from tbroy into @tbname
while @@fetch_status=0
begin 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
BEGIN
select 包含字串的表名=@tbname
--exec( 'select distinct '+@colname+' from ' +@tbname + ' where '+ @colname+ ' like '+ '''%'+@string+ '%''')
END
fetch next from colroy into @colname
end close colroy
deallocate colroy fetch next from tbroy into @tbname
end
close tbroy
deallocate tbroy
end
然后execute,输入指定值即可.
