Oracle删除匹配多个值的行 [英] Oracle Delete Rows Matching On Multiple Values
本文介绍了Oracle删除匹配多个值的行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想做类似的事情:
DELETE FROM student WHERE
student.course, student.major IN
(SELECT schedule.course, schedule.major FROM schedule)
但是，似乎您只能在IN运算符中使用一列.真的吗?看起来像这样的查询应该是可能的.
However, it seems that you can only use one column with the IN operator. Is that true? Seems like a query like this should be possible.
推荐答案
不，您只需要括号即可.
No, you just need parentheses:
DELETE FROM student WHERE
(student.course, student.major) IN
(SELECT schedule.course, schedule.major FROM schedule)
