    Hi,

    In the CODD's rules,

    'Comprehensive Data Sublanguage Rule' section,it's mentioned that

    SQL is a linear, non-procedural or declarative language.

    What are the differences between the terms -

    liner,non-procedural and declarative languages?

    Thanks,

    Jag

    A language has a linear syntax if it can be invoked using character strings.

    A non-procedural (or declarative) language is one where the programmer need not determine exactly how to get the desired result; one declares the desired result, but not the procedures necessary to derive it.
