我要查找值为‘WSCOL1525’的字段。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

declare @cloumns varchar(40)
declare @tablename varchar(40)
declare @str varchar(40)

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

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
