格式化字符串到日期

Question

我有约会对象：'Fri Jul 24 13:11:04 CEST 2015'。如何将此字符串转换为日期？最后我想做这样的事情：

to_char('Fri Jul 24 13:11:04 CEST 2015', 'DD/MM/YYYY HH24:MI:SS')

我尝试了一些方法，但到目前为止都失败了，出现了这个错误：

ORA-01858:  -  "a non-numeric character was found where a numeric was expected"
*Cause:    The input data to be converted using a date format model was
           incorrect.  The input data did not contain a number where a number was
           required by the format model.
*Action:   Fix the input data or the date format model to make sure the
           elements match in number and type.  Then retry the operation.

我在这里可以做我想做的事吗？

你需要使用to_date:

to_date('Fri Jul 24 13:11:04 CEST 2015', 'DD/MM/YYYY HH24:MI:SS')

to_char 只需要数字
