Errors

All DB-related errors manifest themselves as exceptions of type SOCIError, which is derived from std::runtime_error.
This allows to handle database errors within the standard exception framework:

int main()
{
try
{
// regular code
}
catch (exception const &e)
{
cerr << "Bang! " << e.what() << endl;
}
}


Portability note:

The Oracle backend can also throw the instances of the OracleSOCIError, which is publicly derived from SOCIError and has an additional public errNum_ member containing the Oracle error code:

int main()
{
try
{
// regular code
}
catch (OracleSOCIError const &e)
{
cerr << "Oracle error: " << e.errNum_
<< " " << e.what() << endl;
}
catch (exception const &e)
{
cerr << "Some other error: " << e.what() << endl;
}
}
