3706 Syntax error: expected something between an integer and ')'

Question

我正在努力找出问题所在，我的部分代码如下所示

(sel no_2, sum(L) from (
                sel no_2, colB, count(distinct(colC))
                from dbA.tblP as p
                    join dbB.tblI as i on p.id = i.id and p.no = i.no
                    join dbB.tblT as t on i.no_2 = t.no_2
                    join dbA.mp_tblA as a on t.no_2 = a.no_2) l 
                    ) as l
group by 1) as l

Teradata 指向其中的 group by 1)。我应该在“1”和“）”括号之间放什么？有什么办法可以解决吗？

Answer 1

看起来你有一个额外的 ) l 导致语法错误。试试这个：

SELECT no_2, SUM(L) 
FROM (
  SELECT no_2, colB, COUNT(DISTINCT colC) AS no_colC
  FROM dbA.tblP AS p
  INNER JOIN dbB.tblI AS i ON p.id = i.id AND p.no = i.no
  INNER JOIN dbB.tblT AS t ON i.no_2 = t.no_2
  INNER JOIN dbA.mp_tblA AS a ON t.no_2 = a.no_2
) AS l
GROUP BY 1

关于可读性的一些建议，以及评论：

使用SELECT代替SEL
指定 INNER JOIN 而不是 JOIN
如果你打算使用 count(distinct(colC)) 给它一个别名，比如 no_colC

此外，您在 SUM(L) 中引用的 "L" 值是多少？除非您将该字段包含在子 select.

中，否则查询将不会按原样工作
