SQL Parser (C++)

This is a SQL Parser for C++. It parses the given SQL query into C++ objects. It is developed for integration in hyrise (https://github.com/hyrise/hyrise), but can be used in other environments as well.

General Usage

Prerequisites:

• bison (https://www.gnu.org/software/bison/)
• flex (http://flex.sourceforge.net/)

To create the full parser code run make build. The parser library code is created in build/.

To use the SQL Parser in your own code, you only need to include SQLParser.h and build+link all the source files from the parser with your project. See hyrise/src/lib/access/sql/SQLQueryParser.cpp for how it's used in Hyrise.
