SQL Server Calculated Column

Question

I have two columns, both int's, Wins and Losses. I have a calculated column WinPercentage as a decimal(14,3), I want this to be:

WinPercentage = (Wins + Losses) / Wins

What's the syntax for that?

Answer 1

CREATE TABLE WinLoss
(
 TeamId int IDENTITY(1,1) NOT NULL,
 Wins int,
 Losses int,
 WinPercentage AS CASE WHEN wins > 0 THEN (Wins + Losses) / Wins ELSE 0 END
)
