推荐答案

尝试将字符串转换为数字时出现 ORA-01722 错误，并且字符串无法转换为数字.

An ORA-01722 error occurs when an attempt is made to convert a character string into a number, and the string cannot be converted into a number.

在没有看到您的表定义的情况下，您似乎正在尝试将值列表末尾的数字序列转换为数字，而分隔它的空格会引发此错误.但根据您提供给我们的信息，它可能发生在任何领域(第一个领域除外).

Without seeing your table definition, it looks like you're trying to convert the numeric sequence at the end of your values list to a number, and the spaces that delimit it are throwing this error. But based on the information you've given us, it could be happening on any field (other than the first one).
