golang version of SQL parser, substential copy-and-past from the book <flex & bison>
= sql-parser
sql-parser is parser substantially copy-and-paste from the book <flex & biosn>
- generates Reverse Polish Notation (RPN) of SQL statements
- integrates with GO's yacc and nex instead of Flex & BISON
I wrote this code to get acquainted with GO and SQL for further develop purpose. This is a subset of SQL. The ultimate definitions for SQL are the standards documents published by ANSI and ISO including ISO/IEC 9075-2:2003, which defines SQL, and a variety of related documents that define the way to embed SQL in other programming languages and in XML.
