Hi all experts,
I am designing a program of telephone directory in C++, which will have database of all personal information entered by users. Now I want to have automatic number counter which will be displayed before showing final result like a waiting counter. Can anyone help me in coding for enabling a automatic number counter in my program.
How to enable automatic number counter.
Hello Mark Lesliez,
You can integrate with your SQL command to generate automatic numbers just use the "SELECT MAX(Field_Name) as Variable from Table_Name" and add 1 so that it will increase or the increment method. For example:
res = stmt->executeQuery("SELECT MAX(Notes) as noteNum FROM Tasks");
count = int(noteNum) + 1;
I have not checked that in C++ since I don't use C++ anymore (I've used that for 4 years ago). Just use the idea I have given you. I hope that would help you.
