How to pass NULL to INOUT parameter for stored procedure?
-
I am using QSqlQuery to execute a stored procedure, the first parameter is defined as INOUT, I declared this as QVariant biDataset(QVariant::String); which I think is ok to pass it in as NULL. I then want the procedure to passbook the value into biDataset so on future calls its passed back in.
However I'm not sure this is correct, can anyone verify ?
