I kept developing simple databases that did not require sql solution but recently it is starting to be not sufficient, I have more and more demanding customers and I need to start using SQL.
My question is which book you could recommend for someone new to SQL? I got quite a good grip on access itself and starting to be quite confident with VBA.
Also what software would you recommend? Obviously the cheaper the better. I was looking into Microsoft SQL Express edition but maybe you have different view.
