Programming Transact SQL is one of the best and most useful computer books I have come across in 35 years of living with a manual in my lap. It's fun to read(if you're a geek), it's accurate, it's thorough, it's programmer friendly. It doesn't waste my time or leave me reaching for another reference in the middle of a task. I've urged my children and friends(the ones working on database projects) to buy it. The authors really know their stuff. I'm impressed and pleased.
