Handle Exceptions

[eluser]alejandronanez[/eluser]
Hey everybody it's me again.

I'm working with Oracle XE, I developed a form for creating new data on one of my tables but that table has a UNIQUE KEY restriction, and when I insert an existing record CI says this.

A Database Error Occurred

Error Number:


INSERT INTO "table" ("field2", "field3") VALUES ('name', 'last name')

How can I handle this exception?

Any suggestion?

Thanks!
