SQL*Plus is a TOOL, an interface, NOT a language. You can use either SQL or PL/SQL with it, the same as you can with various other interfaces.

PL/SQL is an extension, or superset of SQL that allows you to do things that SQL itself can't (e.g. IF..THEN..ELSE)..the PL stands for "Procedural Language"..each major vendor has a similar tool. Sybase, for instance, uses "Transact SQL" which adds the same sorts of features to SQL as PL/SQL does.

The definition of " := " has been answered by the other posters..

Take care,

Steve
