CppCrate is a C++ interface for Crate http://crate.io. It supports normal SQL based queries โ including statements with parameter substitution and bulk operations โ and provides an interface to manage blob data.
CppCrate is in a very early development phase so there are no API guaranties currently. The API may change with any release.
Using CppCrate is straight forward: Create a client, connect to a node and make your request:
CppCrate::Client client;
if (client.connect("localhost:4200")) {
CppCrate::Result result = client.exec("SELECT id, name FROM players");
if (result) {
for (int i = 0, total = result.recordSize(); i < total; ++i) {
CppCrate::Record record = result.record(i);
std::cout << "Result " << (i+1) << ": "
<< record.value("name").asString()
<< " (" << record.value("id").asString() << ")\n";
}
}
}

CppCrate uses CMake and requires that CURL is available. Anything else is standard:
- Clone the repository
- Run CMake
- Run
make
For CMake CppCrate provides these options:
- ENABLE_BLOB_SUPPORT If enabled, CppCrate also provides an interface to deal with BLOB data.
- ENABLE_CPP11_SUPPORT If enabled, CppCrate uses C++11 features to improve performance. This requires a C++11 compatible compiler of course.
