Upgrade the `bnf2html.pl` script to spot repeated rule definitions. Update `sql-2003-2.bnf` and `sql-99.bnf` to eliminate various repeated rules. The repeats in SQL-99 mostly come from extra information in 9075-4 (SQL/PSM) and 9075-5 (SQL/Bindings). The repeat in SQL-2003-2 was similar.

    - The plain text .bnf files were converted to HTML by the Perl script - bnf2html which you may use if you wish. - The bnf2html script also uses the C program - WEBCODE version 1.09 - which you can download as a gzipped tar file. -

    - -

    - See also bnf2yacc , an experimental - script to convert BNF into an outline Yacc grammar. - The generated grammar typically includes some unacceptable tokens, such - as %token 0, that should be handled by the lexical analyzer - rather than the grammar. - The SQL standard includes such rules as grammar rules. -

    - (The Perl scripts should normally be renamed after downloading.) -

extracted manually from sql-2003-2.bnf by Domingo Alvarez Duarte. +Many thanx Domingo! + +It is the latter file as pure ebnf, i.e. with the original markup stripped. + +It can be rendered as railroad diagrams on the website https://www.bottlecaps.de/rr/ui. +Just copy it into the Edit Grammar tab, and click View Diagram. Then wait a moment :-). + +Domingo notes: +1. Non reserved words appear with * as suffix, ex: SUBSTRING -> SUBSTRING*. + +2. You can navigate through the grammar by clicking the rectangular boxes. + +Finally, you can download the rendered railroad as either XHTML + SVG or HTML + PNG.
