在 Oracle 中将字符串日期转换为日期时间

Using this code throws an error:

TO_DATE('2011-07-28T23:54:14Z',  'YYYY-MM-DD HH24:MI:SS')

如何做到这一点?

Error report:
SQL Error: ORA-01861: literal does not match format string
01861. 00000 -  "literal does not match format string"
*Cause:    Literals in the input must be the same length as literals in
           the format string (with the exception of leading whitespace).  If the
           "FX" modifier has been toggled on, the literal must match exactly,
           with no extra whitespace.
*Action:   Correct the format string to match the literal.

更新:-

TO_DATE('2011-07-28T23:54:14Z', 'YYYY-MM-DD"T"HH24:MI:SS"Z"')
