SOCI ODBC连接错误

Question

I am trying to connect the SOCI library to my database but keep on receiving this error on my VS compiler output.

My code is :

{
  try
  { 
    backend_factory const& backEnd = odbc;
    std::string const & connectString = "DSN=CVD_SQL_connection_2016b_64bit";
    session sql(backEnd, connectString);

  }
  catch (const std::exception& e)
  {

    cerr << e.what();
  }

  return 0;
}

The error warnings are the following:

Can someone please guide me about what I am doing wrong?

Answer 1

You can use

#define _CRT_SECURE_NO_WARNINGS

or

#pragma warning(disable : 4996)

to suppress the warning.

Or use:

#define _CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES 1

to let the compiler automatically replace strcpy() with strcpy_s() for you. See here for more

To connect to ODBC you can use a connection_parameters object to pass the connection details as follows:

connection_parameters parameters("odbc", "DSN=CVD_SQL_connection_2016b_64bit");
parameters.set_option(odbc_option_driver_complete, "0");
session sql(parameters);

Don't forget to include the soci-odbc.h
