Some time ago, I made a small tool for information synchronization, and used VC database programming. Writing this log should be a simple note. It can also be used as a reference for beginners. This article describes how VC connects to the DB2 database through the ODBC/CLI driver and lists someCodeAnd has the following functions: 1. Establish a connection;
