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.
|
|
|
|
### Update in Hyrise
|
|
|
|
Run `./deploy_to_hyris.sh path/to/hyrise` to update the SQL parser within Hyrise.
