尝试使用 ORDER BY 时出现 ORA-01722

Question

我有以下简单的 SQL 查询，其中 returns 数据正常：

select ticket_id,executor_id
from e2efr
where executor_id in (60882,91279)

当我想排序时：

select ticket_id,executor_id
from e2efr
where executor_id in (60882,91279)
order by ticket_id

我收到错误消息：

ORA-01722: invalid number
01722. 00000 -  "invalid number"
*Cause:    The specified number was invalid.
*Action:   Specify a valid number.

怎么可能！？

Answer 1

只需将数字作为字符串给出即可。 executor_id 中的某些值无法转换为数字，因此出现错误。

select ticket_id,executor_id
from e2efr
where executor_id in ('60882','91279')
order by ticket_id

ORA-01722 when trying to use ORDER BY
