1.查找字段在库中哪个表
如果要查找FName
select a.name,b.name from syscolumns a inner join sysobjects b on a.id=b.id
where a.name = 'FName'
2.查找数据值在哪个表中
如果要查找 制动器组
declare @cloumns varchar(40)
declare @tablename varchar(40)
declare @str varchar(40)
declare @counts int
declare @sql nvarchar(2000)
declare MyCursor Cursor For
Select a.name as Columns, b.name as TableName from syscolumns a,sysobjects b,systypes c
where a.id = b.id
and b.type = 'U'
and a.xtype=c.xtype
and c.name like '%char%'
set @str='制动器组'
Open MyCursor
Fetch next From MyCursor Into @cloumns,@tablename
While(@@Fetch_Status = 0)
Begin
set @sql='select @tmp_counts=count(*) from ' +@tablename+ ' where ' +@cloumns+' = ''' +@str+ ''''
execute sp_executesql @sql,N'@tmp_counts int out',@counts out
if @counts>0
begin
print '表名为:'+@tablename+',字段名为'+@cloumns
end
Fetch next From MyCursor Into @cloumns,@tablename
End
Close MyCursor
Deallocate MyCursor
亲测可用，但是第二项查找数据会报错，希望哪个大神帮忙解决报错问题。
