hi i'm working with my inventory system and i want to know more about "Connecting my database using QUERY" please give me some ideas on how to work with queries! i'm looking forward to answer my questions. god bless!!
I'm afraid your question is quite broad, and as such you may not get the response(s) you're after. Having said that, there's always the "trusty" Google results for whatever you're looking at. About the only tutorial on this that I have bookmarked would be the one from Martin Green. Otherwise there are plenty of good books out there on the subject, or even entire college courses devoted to SQL.
