sql - Access97 左连接选择

Question

我被一些access97 sql卡住了，

SELECT Master.Text, Sub.Cnt
FROM Master
INNER JOIN [
SELECT Number, COUNT(*) As Cnt FROM SubTable GROUP BY Number]. AS Sub
ON Master.Number=Sub.Number
WHERE Master.Number=1;

行为如我所料但是在我需要将“子表”名称方括号括起来的地方我在 FROM 子句中突出显示 GROUP 时收到一个错误

SELECT Master.Text, Sub.Cnt
FROM Master
INNER JOIN [
SELECT Number, COUNT(*) As Cnt FROM [Sub Table] GROUP BY Number]. AS Sub
ON Master.Number=Sub.Number
WHERE Master.Number=1;

谁能指出我正确的方向？

谢谢

方括号在查询中看起来很奇怪。尝试对子查询使用常规括号：

SELECT Master.Text, Sub.Cnt
FROM Master INNER JOIN 
     (SELECT Number, COUNT(*) As Cnt
      FROM [Sub Table]
      GROUP BY Number
     ) AS Sub
     ON Master.Number = Sub.Number
WHERE Master.Number = 1;

编辑：

您可以将此查询重写为：

SELECT Master.Text, COUNT(*) as Cnt
FROM Master INNER JOIN 
     [Sub Table] as sub
     ON Master.Number = Sub.Number
WHERE Master.Number = 1
GROUP BY Number;
