MySql C++ connector getString() doesn't work correctly, while getInt works perfectly

Question

I tried to connect C++ to MySql and I just can\'t get this to work properly. I used latest MySql and C++/Connector for Windows from Oracle site. I also use VS2010.

Answer 1

I trial run the demo source codes from MySQL Connector/C++ Developer Guide / Getting Started with Connector/C++: Usage Examples / Complete Example 1 in the environment "mysql-connector-c++-8.0.13-win32" and Visual C++ 2015.

I also encountered the same problem.

In debug mode, it should use

std::string version = result->getString( COLUMN_NAME ).c_str();

But in release mode, this is OK:

sql::SQLString sString  = result->getString( COLUMN_NAME );

I believe it is because my project must been compiled with the same runtime with the MySQL C++ Connector library.
