embeddable C++ SQL runtime, supports ChartSQL extensions
Requires cmake
git clone git@github.com:paulasmuth/chartsql.git
cd chartsql
make
Most simple example: evaluate a constant expression without inputs:
#include <csql/csql.h>
#include <string>
int main() {
auto runtime = Runtime::getDefaultRuntime();
auto txn = runtime->newTransaction();
std::string expression = "1 + 2";
auto res = runtime->evaluateConstExpression(txn.get(), expression);
std::string res_str = v.toString();
printf("result: %s\n", re_str.c_str()); // prints "result: 3"
return 0;
