Passing parameters by value has several drawbackswhich should be borne in mind. First of all, it makes the function body more complex, which creates a maintenance and readability burden. For example, in the code above, we've added astd::movecall, which creates a risk of accidentally accessing...

ParameterValuePtr can be any non-null pointer value that will be returned by SQLParamData as the user-defined token whose value was passed with ParameterValuePtr for both input and output. For more information, see Retrieving Output Parameters Using SQLGetData. SQL_PARAM_OUTPUT_STREAM. Same as...
When you pass a parameter by value, you're passing the value of a variable to a procedure. This method is always the case by default with fundamental types.In the next example, the function MyFunction gets a parameter of type integer, changes the value, and returns the value of paramA....
