Oracle To_date Format
below code to_date('1311313', 'yymmdd') which actually throws exception with saying invalid month. Which is can manage as exception when others then sop('date format is wrong'); Here the problem is everything will get caught which I do not want to do as if some other error will occur then also it will pass the message date format is wrong. I also do not want to create a user defined exception. Just want to know oracle date format which exception is being thrwon out so that I can use in my code like below exception when name_of_exception then sop('date format is wrong'); oracle exception plsql to-date share|improve this question edited Nov 18 '13 at 7:42 Nicholas Krasnov 19.2k42849 asked Nov 18 '13 at 7:09 gahlot.jaggs 1961517 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted There are at least two approaches to handle different exceptions raised during an attempt to convert character literal to a value of DATE data type: Define as many exception names and associate them with Oracle error codes, using exception_init pragma, as many exceptions to_date() function is able to raise. Create a stand alone, or part of a package, wrap-up function for to_date() function, with one when others exception handler. Personally I lean toward the second one.
