我收到此错误消息。谁能帮我解决我的查询问题？使用光标的正确方法是什么？
此存储过程应从临时表中获取数据并将其插入两个不同的表中。临时表中的某些列，例如EID, FN, MN, LN应该插入表dbo.tblUser中，而临时表中的其余列应该在表dbo.refRoster_Details中。
在这件事上请帮我。
16950消息，州立2级，第22行，
变量'@MyCursor'当前没有分配游标。第16层，状态2，第96行，短信16917
光标未打开。16917级第1州第227行的短信

... DECLARE @MyCursor CURSOR OPEN @MyCursor SET @MyCursor = CURSOR FAST_FORWARD FOR ...
在将光标分配给OPEN之前，请先调用@MyCursor。在OPEN @MyCursor之后移动SET @MyCursor = CURSOR FAST_FORWARD FOR ...。
SET @MyCursor = CURSOR FAST_FORWARD FOR
...
ORDER BY [SAP ID] DESC
OPEN @MyCursor
但是我不知道为什么您对SELECT TOP 1查询完全使用游标。 SELECT @var = col ...和ID @@rowcount = 1只能处理发现数据的情况。
