    Looking for authoritative reference on PL/SQL grammar

    Hi. We are working on tools to process PL/SQL code.
    What we need are precise details on the full PL/SQL syntax.

    We have the Oracle 9/10 documentation, but it seems
    a little fuzzy on the details. As an example, we're unclear
    on whether ANSI 99 JOIN syntax is allowed or not.
    (Any direct answers on this topic would be appreciated).

    Is there a document which precisely defines the PL/SQL
    syntax?

    With all due respect,

    One could get the impression you are unclear about PL/SQL in general.
    Your comment about the ANSI 99 Join syntax indicates that you do not
    separate PL/SQL from SQL and therefore may not realize that PL/SQL does
    perform any joins at all. Instead, it passes such requests to the SQL
    processor, the syntax for which is documented in the SQL Reference
    Manual.

    I also hope you realize that the combination of SQL and PL/SQL allows a
    developer to 'extend' SQL by adding new functions that can be used in
    various places, extending the the SELECT clause, the inline view,
    the WITH clause, the WHERE clause, etc. You may find this a challenge in
    creating your tools as it implies you may need to catalog all stored
    functions as well.

    The actual PL/SQL language is documented fairly well in the "PL/SQL User's
    Guide and Reference", which includes use, discussion of the above
    concept, syntax and examples. Please indicate what is 'fuzzy' about
    details such as the following syntax definition (from the manual) for the
    CASE statement:


    searched_case_s tatement ::=

    [ <<label_name> > ]
    CASE { WHEN boolean_express ion THEN {statement;} ... }...
    [ ELSE {statement;}... ]
    END CASE [ label_name ];


    And yes, ANSI 99 Join syntax is allowed - in the SQL language.

    BTW - if your tool is intended to generate PL/SQL, I strongly encourage
    reading and understanding "Effective Oracle By Design" as well as anything
    else identified at http://www.oaktable.org

    By the way, cross-posting is not necessary. comp.databases. oracle is an
    obsolete newsgroup, comp.databases. oracle.marketpl ace is for
    advertising, comp.databases. oracle.tools is for Oracle tools. Pick one
    and stick with it.

    I cross-posted the reply so you get the response, but on behalf of [many
    in] the community, I would appreciate you restricting the rest to
    comp.databases. oracle.tools)

      Both ANSI and ISO join syntaxes are supported.
