After so many years of mixing in the forum, we have seen an obvious trend: more and more netizens are using VFP and SQL server for the system. Many people are concerned about how to operate or manage SQL Server from VFP. You can use views, SPT, or ADO to perform data operations on SQL Server. However, to manage the server itself, it seems that only SPT can be use
