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.
Run tests
To execute all tests run: ./run_tests.sh.
Update in Hyrise
Run ./deploy_to_hyris.sh path/to/hyrise to update the SQL parser within Hyrise.
