Does anyone here have experience working with PL/SQL? I need some help getting started...

1 Answer

Answer :

answer:PL/SQL is Oracle’s take on SQL. It’s mostly “vanilla” SQL, but with some Oracle-specific twists. You need Oracle SQL Developer or something similar. I doubt other relational databases can handle the specific differences that turn SQL into something more closely resembling a true object-oriented language, so make sure you get something Oracle-specific!.
