sql - 使用 union all 将变量插入临时表

Question

为什么我在“dbo”附近得到不正确的语法。错误？

SELECT inv_num
INTO #InvoiceList
FROM (
SELECT inv_num = 
    dbo.ExpandKy(10, @Inv1) UNION ALL
    dbo.ExpandKy(10, @Inv2) UNION ALL
    dbo.ExpandKy(10, @Inv3) UNION ALL
    dbo.ExpandKy(10, @Inv4) UNION ALL
    dbo.ExpandKy(10, @Inv5) UNION ALL
    dbo.ExpandKy(10, @Inv6) UNION ALL
    dbo.ExpandKy(10, @Inv7) UNION ALL
    dbo.ExpandKy(10, @Inv8) UNION ALL
    dbo.ExpandKy(10, @Inv9) UNION ALL
    dbo.ExpandKy(10, @Inv10) UNION ALL
    dbo.ExpandKy(10, @Inv11) UNION ALL
    dbo.ExpandKy(10, @Inv12) UNION ALL
    dbo.ExpandKy(10, @Inv13) UNION ALL
    dbo.ExpandKy(10, @Inv14) UNION ALL
    dbo.ExpandKy(10, @Inv15) UNION ALL
    dbo.ExpandKy(10, @Inv16) UNION ALL
    dbo.ExpandKy(10, @Inv17) UNION ALL
    dbo.ExpandKy(10, @Inv18) UNION ALL
    dbo.ExpandKy(10, @Inv19) UNION ALL
    dbo.ExpandKy(10, @Inv20)
) d
WHERE inv_num IS NOT NULL

Answer 1

您的联合查询无效。它应该类似于这个

select dbo.Exandkey(10, @Inv1) invnum
union all
select dbo.Exandkey(10, @Inv2) invnum
etc
