Hi all,

As of now i am not looking for validation, i know the validation will automatically done but if you see by default it will not raise any error message if you fill any wrong value in text item with date data type. It will freeze the cursor to the text item.That is NOT the default. The default is to issue various FRM-nnnnn messages, between 50002 and 50026. From notes I have:
-- 50002: Month must be between 1 and 12.
-- 50003: Year must be 00-99 or 1000-4712
-- 50004: Day must be between 1 and last of month.
-- 50012: Date must be entered in a format like <fxMMDDRR>
-- 50017,18,19: Hour,Min,Sec must be between 0 and 23,59,59.
-- 50025: Date/time must be entered in a format like <xxyytttt>
-- 50026: same as 50012 and 50025 with <yyyy> year.
And from my old, dusty copy of the Oracle Developer/2000 "Messages and Codes Manual", those messages have an error level = 15.
If you are not seeing those messages, then you have done one of two things:
1. Set your System.Message_Level to a value of 15 or higher. You should NEVER set it above zero, since all that does is hides error messages like these. If you want to bypass or prevent an error message, it should be handled in the Re: FRM-40735:Pre_Insert trigger raised unhandled exception ORA-20011.
2. You have some bad code in an On-Error trigger that fails to handle errors correctly.
