我有以下查询。

DECLARE @PartNo Char(22)
DECLARE @PartIssue AS CHAR(4)
DECLARE @Level AS INT
DECLARE @PartType AS CHAR(12)
DECLARE @TempLeadTime AS FLOAT
DECLARE @CumLeadTime AS FLOAT

DECLARE @ldtimeforcursor AS FLOAT
DECLARE @temp_level as float
DECLARE @BomParent as NVARCHAR(50)
DECLARE @ldt as NVARCHAR(50)
DECLARE @TestCursor as CURSOR

SELECT @PartIssue = drawissno, @PartNo = partnum, @Level=1, @PartType = sm FROM partmaster  where partnum = 'AE40-0287810'

WITH Hierarchyct(BOMLevel,bmchild, parttype, bomparent, bmqty, leadtime, childissue,bmethod,rmethod, requiredqty) AS
      (SELECT     @Level AS BOMLevel,

      WHERE eccpart = @PartNo AND eccissueno = @PartIssue 

      UNION ALL
      SELECT            (hierarchyct.BOMLevel + 1) AS BOMLevel,

                        (CASE WHEN LTRIM(RTRIM(bom.bomissue)) = 'CURR' THEN (SELECT drawissno FROM PartMaster WHERE PartNum = bom.bomchild) ELSE bom.bomissue END) AS childissue,

                       -- @CumLeadTime + leadtime as cumleadtime

      WHERE bom.baltmethod =(SELECT eccbom FROM eccissue WHERE eccissue.eccpart = hierarchyct.bmchild AND eccissue.eccissueno = hierarchyct.childissue )
      )


SELECT * 
FROM
(     
SELECT      hierarchyct.*,

GROUP BY BOMLevel,bmchild, parttype, bomparent, bmqty, leadtime, childissue,bmethod,rmethod, requiredqty, stleadtim, sm, part
--Where leadtime =0Mr1990
) as temp

这很好，但是当我尝试使用这个修改过的查询将最终结果放入临时表（我需要这个来运行游标）时：

我收到以下错误。

  

Msg 2714，Level 16，State 1，Line 51
  已经有一个名为＆＃39; #CumLeadTimRep＆＃39;在数据库中。

     

Msg 156，Level 15，State 1，Line 62
  关键字＆＃39;附近的语法错误为＆＃39;。

尝试了很多，但它没有得到修复。可能是什么问题？

找到答案。问题在于试图创建一个已经存在的表。正确的语法如下：

DECLARE @TestCursor as CURSOR
