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 might also work, but are untested.
|
||||
|
||||
1. Download the [latest release here](https://github.com/hyrise/sql-parser/releases)
|
||||
2. Compile the library `make` to create `libsqlparser.so`
|
||||
3. *(Optional)* Run `make install` to copy the library to `/usr/local/lib/`
|
||||
3. Run the tests `make test` to make sure everything worked
|
||||
4. Take a look at the [example project here](https://github.com/hyrise/sql-parser/tree/dynamic-library/example)

We strongly encourage you to contribute to this project! If you want to contribute to this project there are several options. If you've noticed a bug or would like an improvement let us know by creating a [new issue](https://github.com/hyrise/sql-parser/issues). If you want to develop a new feature yourself or just improve the quality of the system, feel free to fork the reposistory and implement your changes. Open a pull request as soon as your done and we will look over it. If we think it's good then your pull request will be merged into this repository.

This page contains information about how to extend this parser with new functionalities.
|

## Developing New Functionality
|
||||
|
||||
This section contains information about how to extend this parser with new functionalities.
|
||||
|
||||
|
||||
### Implementing a new Statement
|
||||
|
||||
## Implementing Statement Class
|
||||
|
||||
Create a new file and class in src/lib/statements/ or extend any of the existing Statements. Every statement needs to have the base class SQLStatement and needs to call its super constructor with its type. If your defining a new statement type, you need to define a new StatementType in SQLStatement.h.
|
||||
Create a new file and class in `src/sql/` or extend any of the existing Statements. Every statement needs to have the base class SQLStatement and needs to call its super constructor with its type. If your defining a new statement type, you need to define a new StatementType in `SQLStatement.h`.
|
||||
|
||||
It is important that you create an appropriate constructor for your statement that zero-initializes all its pointer variables and that your create an appropriate destructor.
|
||||
|
||||
Lastly you need to include your new file in src/lib/sqllib.h
|
||||
Finally you will need to include your new file in `src/sql/statements.h`.
|
||||

||||

||||

To extend the grammar the file you will mostly have to deal with is the bison grammar definition in `src/parser/bison_parser.y`.
|

If your extending an existing statement, skip to the non-terminal definition for that statement. I.e. for an InsertStatement the non-terminal insert_statement.

Integration in Hyrise
|
||||
=====================
|
||||
|
||||
On this page we describe how to integrate changes to the parser into Hyrise.
|
||||
|
||||
## Update the Parser code in Hyrise
|
||||
|
||||
Run `./deploy_to_hyrise.sh path/to/hyrise` to update the SQL parser code within Hyrise.
