AND MAGA_TYPE = '0'
AND INFO_MAGA_STATE = 4
AND M.T_INFO_MAGA_CREATE_TIME > TO_DATE('2013-02-01', 'YYYY-MM-DD') --------这句报错
ORDER BY M.INFO_MAGA_CREATE_TIME DESC

参考技术A 你自己写错了，
TO_CHAR(IM.INFO_MAGA_CREATE_TIME, 'YYYY-MM-DD') AS T_INFO_MAGA_CREATE_TIME,

TO_DATE('2013-02-01', 'YYYY-MM-DD')

他们怎么恩那个对比呢？一个CHAR.一个DATE
要不你转换上面的TO_CHAR为TO_DATE
要不你转换下面的TO_DATE为 TO_CHAR

你的SQL 真。。。。乱本回答被提问者采纳

Oracle 查询 ORA-01722

ORA-01722 ： 无效数字。

一般来说，是由于试图将字符串转换为数字的时候失败，具体的原因在于字符串中可能含有不是数字的字符。

出现这种问题的两种可能原因：

1）执行的sql语句中包含显示或者隐式的类型转换，将字符串转换到数字类型的时候失败,字符内容包含非数字字符。解决方法：检查SQL语句是否包含对字段类型的转换。

2）将一个字符(varchar2)字段绑定（DefineByPos）到数字(number)类型，从而在取结果时，转换失败。解决方法：检查绑定变量和对应的字段是否顺序对应，数据类型对应。
