C++ SQL Parser for Hyrise

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.

In March 2015 we've also written a short paper outlining discussing some development details and the integration into our database Hyrise. You can find the paper here.

Usage

Note: You can also find a detailed usage description at this blog post.

Requirements:

• gcc 4.8+ (or clang 3.4+)

To use the SQL parser in your own projects you simply have to follow these few steps. The only requirement for is gcc 4.8+. Older versions of gcc/clang might also work, but are untested.

1. Download the latest release here
2. Compile the library make to create libsqlparser.so
3. (Optional) Run make install to copy the library to /usr/local/lib/
4. Run the tests make test to make sure everything worked
5. Take a look at the example project here
6. Include the SQLParser.h from src/ and link the library in your project

Extending the parser

Requirements for development:

• gcc 4.8+ (or clang 3.4+)
• bison (v3.0.2+)
• flex (v2.5.5+)

First step to extending this parser is cloning the repository git clone git@github.com:hyrise/sql-parser.git and making sure everything works by running the following steps:

make parser   # builds the bison parser and flex lexer
make library  # builds the libsqlparser.so
make test     # runs the tests with the library

Rerun these steps whenever you change part of the parse. To execute the entire pipeline automatically you can run:

make cleanall  # cleans the parser build and library build
make test      # build parser, library and runs the tests
