SQL Server计算列

Question

我有两列,包括int,Wins和Losses.我有一个计算列WinPercentage的decimal(14,3),我想这是:

WinPercentage = (Wins + Losses) / Wins

那是什么语法？

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
)
