How to validate a date item "DD/MM/YYYY HH24:MI" ?

Question

Hi,
I want to create a validation item. I have a date item usinhg this mask : "DD/MM/YYYY HH24:MI".
I want to validate if a date entered according to this syntax "DD/MM/YYYY HH24:MI"
Unfortunately APEX gives me only the choice to validate if a date is under the form "DD/MM/YYYY" which gives this syntax :
^([012]?[[:digit:]]|3[01])/(0?[[:digit:]]|1[012])/[[:digit:]]{4}$I don't know this syntax, do you know how I could transform it (I mean adding the hours and minutes criteria) to attain my goal ?
Sorry for my english, not perfect, today !
Regards,
Christian

Try this:
SELECT REGEXP_INSTR('04-OCT-2011 23:12',
'^([012]?[[:digit:]]|3[01])-(JAN|FEB|MAR|APR|MAY|JUN|JUL|AUG|SEP|OCT|NOV|DEC)-[[:digit:]]{4}[[:space:]][0-2][0-9]:[0-9][0-6]$') test_result
FROM dualFor case-insenstive matching, use below:
SELECT REGEXP_INSTR('04-OCT-2011 23:12',
'^([012]?[[:digit:]]|3[01])-(JAN|FEB|MAR|APR|MAY|JUN|JUL|AUG|SEP|OCT|NOV|DEC)-[[:digit:]]{4}[[:space:]][0-2][0-9]:[0-9][0-6]$',1,1,0,'i') test_result
FROM dualThanks!
