In a oracle table column, there is a varchar2 column which contains value '2017-02-14T18:04:34.988+00:00' I need to convert it to timestamp. I am using TO_TIMESTAMP() to convert but I am not able to find out what date mask I need to provide. I have tried with

sql> select to_timestamp('2017-02-14T18:04:34.988+00:00','YYYY-MM-DD HH24:MI:SS.FF') from dual ;

But it does not work.

Kindly suggest what datetime mask I have to specify as 2nd argument.

According to ISO 8601 T is the time designator. You need to use a constant "T" in your date format mask.

And your time stamp contains timezone so you need to use TO_TIMESTAMP_TZ function to achieve this.

SQL> select to_timestamp_tz('2017-02-14T18:04:34.988+00:00',' YYYY-MM-DD"T"HH24:MI:SS.FF TZH:TZM') from dual;
