Reserved Words

As we mentioned earlier in this book, the PL/SQL language recognizes certain identifiers (language keywords and identifiers from the STANDARD package) as having special meaning. You must not redefine these reserved words as identifiers in your programs.

We compiled the following table of reserved words by taking the list Oracle publishes in the V$RESERVED_WORDS data dictionary view and trying to declare them (as variables and/or procedures). If the declarations failed, we added the words to the list. Avoid using these words in your programs.
