我无法弄清楚为什么(或者你可能不能这样做)我得到了超出范围的错误
Must declare the scalar variable “@CompanyGroupSites_Master.
那么我无法在我的Cursor中以这种方式访问我的Table变量,或者我一定错过了一些简单的东西,当从光标体内引用时保持该表变量超出范围?
DECLARE @TotalCompaniesToProcess int SET @TotalCompaniesToProcess = (select distinct Count(BusinessLine) from vwBuisinessUnit) IF(@TotalCompaniesToProcess > 0) BEGIN ---------------- ############# SETUP ############# ---------------- DECLARE @Companies TABLE (Company varchar(30)) Insert Into @Companies select distinct Company from Companies DECLARE @CompanyGroups_Added TABLE( CompanyGroupDesc varchar(50),size varchar(50) ) DECLARE @CompanyGroupSites_Added TABLE ( CompanyGroupID int,CompanyID varchar(12) ) DECLARE @CompanyGroupSites_Master TABLE ( CompanyGroupID int,CompanyID varchar(12) ) Insert into @CompanyGroupSites_Master select CompanyGroupID,CompanyID from Sec.CompanyGroupSites DECLARE @CompanyGroupID int DECLARE @Company int ---------------- END SETUP ---------------- ---------------- UPDATE THE COMPANIES ---------------- DECLARE Companies_Cursor CURSOR FOR (select distinct BusinessLine from vwBuisinessUnit) --select distinct BU,BusinessLine from vwBusinessUnit Open Companies_Cursor Fetch NEXT FROM Companies_Cursor into @Company WHILE @@FETCH_STATUS = 0 BEGIN -- is there an existing CompanyGroup for this Organization? If not create it SET @CompanyGroupID = ( select CompanyGroupID from Sec.CompanyGroup where size = 'Business' and CompanyGroupDesc = @Company) IF(@CompanyGroupID < 1) BEGIN INSERT INTO @CompanyGroups_Added ([CompanyGroupDesc],[Size]) VALUES (@Company,'Business') SET @CompanyGroupID = @@IDENTITY select @CompanyGroupID as CompanyGroupID_Added -- testing END Select ToDelete.* from ( select CompanyGroupID,Company from @CompanyGroupSites_Master where @CompanyGroupSites_Master.CompanyGroupID = @CompanyGroupID) as ToDelete delete from @CompanyGroupSites_Master where @CompanyGroupSites_Master.CompanyGroupID = @CompanyGroupID Fetch NEXT FROM Companies_Cursor into @Company END CLOSE Companies_Cursor DEALLOCATE Companies_Cursor END
解决方法
这是一个
long standing parser issue.您需要摆脱表前缀或将其包装在方括号中。
即
delete from @CompanyGroupSites_Master where CompanyGroupID = @CompanyGroupID
要么
delete from @CompanyGroupSites_Master where [@CompanyGroupSites_Master].CompanyGroupID = @CompanyGroupID
不
delete from @CompanyGroupSites_Master where @CompanyGroupSites_Master.CompanyGroupID = @CompanyGroupID
