In SQL Server (2012), I want to divide the values of 2 columns. There are cases where there will be division by zero. I want to do the calculation and handle the division by zero gracefully. A simple example is AB / Hits to get Average. Some AB fields will be zero. Some sort of If statement? If AB = 0, then Average = ".000", else AB/Hits? Thanks for any help.
