Using Oracle to date function for date string with milliseconds

Question

I have to perform some inserts into an Oracle DB  I have some dates  in the following format   23 12 2011 13 01 001    Following the documentation I wrote inserts to date as follows   to date  23 12 2011 13 01 01    DD MM YYYY HH24 MI SS     which works properly  Now I have dates with milliseconds with the format   23 12 2011 13 01 001    I ve tried the following   to date  23 12 2011 13 01 001    DD MM YYYY HH24 MI SSFF3     which is incorrect  delivers an error 01821  00000 -   date format not recognized     Which  String  should I use for this format with milliseconds   Thanks in advance

An Oracle DATE does not store times with more precision than a second   You cannot store millisecond precision data in a DATE column   Your two options are to either truncate the string of the milliseconds before converting it into a DATE  i e    to date  substr  23 12 2011 13 01 001   1  19    DD MM YYYY HH24 MI SS      or to convert the string into a TIMESTAMP that does support millisecond precision  to timestamp   23 12 2011 13 01 001    DD MM YYYY HH24 MI SSFF3

TO DATE supports conversion to DATE datatype  which doesn t support milliseconds   If you want millisecond support in Oracle  you should look at TIMESTAMP datatype and TO TIMESTAMP function   Hope that helps
