C++ SQL Parser
|
||
|
|
=========================
|
||
|
|
[](https://github.com/hyrise/sql-parser/actions?query=branch%3Amaster)
|
||
|
|
|
||
|
|
|
||
|
|
This is a SQL Parser for C++. It parses the given SQL query into C++ objects.
|
||
|
|
It has been developed for integration in [Hyrise](https://github.com/hyrise/hyrise), but can be used perfectly well 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](docs/technical_documentation.pdf).

|
|
## Usage
|
||
|
|
|
||
|
|
**Note:** You can also find a detailed usage description [here](docs/basic-usage.md).
|
||
|
|
|
||
|
|
To use the SQL parser in your own projects you simply have to follow these few steps.
|
||
|
|
|
||
|
|
1. Download the [latest release here](https://github.com/hyrise/sql-parser/releases)
|
||
|
|
2. Compile the library `make` to create `libsqlparser.so`
|
||
|
|
3. *(Optional, Recommended)* Run `make install` to copy the library to `/usr/local/lib/`
|
||
|
|
4. Run the tests `make test` to make sure everything worked
|
||
|
|
5. Include the `SQLParser.h` from `src/` (or from `/usr/local/lib/hsql/` if you installed it) and link the library in your project
|
||
|
|
6. Take a look at the [example project here](https://github.com/hyrise/sql-parser/tree/master/example)
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
#include "hsql/SQLParser.h"
|
||
|
|
|
||
|
|
/* ... */
|
||
|
|
|
||
|
|
{
|
||
|
|
// Basic Usage Example
|
||
|
|
|
||
|
|
const std::string query = "...";
|
||
|
|
hsql::SQLParserResult result;
|
||
|
|
hsql::SQLParser::parse(query, &result);
|
||
|
|
|
||
|
|
if (result.isValid() && result.size() > 0) {
|
||
|
|
const hsql::SQLStatement* statement = result.getStatement(0);
|
||
|
|
|
||
|
|
if (statement->isType(hsql::kStmtSelect)) {
|
||
|
|
const auto* select = static_cast<const hsql::SelectStatement*>(statement);
|
||
|
|
/* ... */
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
