来自oracle表的sql查询

Question

roll number我的oracle表中只有一列.一列中有大量数据.

   roll number  

  -------------

      1 
      2
      3
      4
      5
      .
      .
      .

当我想从这张表中删除一些滚动号码时,我正在写:

delete from table name where roll number='2'; // 1 row deleted.

如果我想5从表中删除那么

delete from table name where roll number='5'; // 1 row deleted.   

同样,当我想要删除100条这样的记录时,我必须更换roll number字段,这是相当的时间.有没有快速方法如何从表中删除选择性行？

Answer 1

如果要删除的ID是连续的,您可以使用BETWEEN:

DELETE FROM your_table WHERE roll_number BETWEEN 5 AND 104

如果没有,你可以使用IN:

DELETE FROM your_table WHERE roll_number IN (5, 9, 110, ... )
