Edit Question
Title
Body
I'm using Oracle 11g, and trying to create a table define constraints on the creation. I was trying to add check constraint to validate some information (like e-mail address, phone number, etc...) Is there something in Oracle 11g that would allow me to do something like this? constraint CK_CONSTRAINT_NAME check (EMAIL like 'REGEX') The regEx I wanted to use (grabbed from regexLib) is: ^[a-zA-Z][a-zA-Z0-9_\.\-]+@([a-zA-Z0-9-]{2,}\.)+([a-zA-Z]{2,4}|[a-zA-Z]{2}\.[a-zA-Z]{2})$ I think Oracle 11g (correct me if I'm wrong) doesn't support this format for RegEx... I've seen methods using REGEX_LIKE, but it seems to only work in WHERE clauses. I'd like to keep it as a check constraint and not a trigger or an external function/script. Also, I've read in other threads here, someone saying RegEx' are not a good way of verifying e-mail address format and such information. No reason was given in the comment, and I'd like to know why, if a reason there is!
