I have read a book also called "dream breaking code" and its English name is "Dream in code". I always think the translation is inaccurate. In that book, I talked about the experiences of a software project, the failures of the Chandler. However, today, t
The table's primary keys are all sequence, and the dataadpter update method is used. I don't know how the predecessors handled it. I am lazy as follows:

Many Access and SQLServer developers often face the problem of upgrading an Access database to an SQLServer database. Because of the existing Access Upgrade Wizard, this transformation process becomes quite simple, especially when you establish an ADP associated with SQLServer data. However, the Wizard is not perfect.
