我有一个从两个表中选择数据的查询。但是,我想让名称只显示一次。即使是与众不同,它也会出现两次。我的查询将粘贴在下面,同时显示当前结果和所需结果。
employeetimesheets表中的数据也粘贴了与rowid'对应的数据。您可以看到它将0.25添加到一起,但是它如何在不增加额外行的情况下查询唯一ID的总和?任何帮助都非常感谢。
SELECT DISTINCT a.rowid,
a.employee,
Sum(b.value) AS TotalHours
FROM employees a
INNER JOIN employeetimesheets b
ON a.rowid = b.empid
WHERE b.title = '50001310-01'
GROUP BY a.rowid,
a.employee,
b.value
当前结果
4 Aa Bus 0.5
4 Aa Bus 1.5
95 Lh Wr 7.5
95 Lh Wr 8
期望的结果
4 Aa Bus 2.0
95 Lh Wr 15.5
RowId' 4'
