2、

　　声明多个变量:
　　DECLARE @s varchar(10),@a INT

　　

多条件选择语句:
Example:

declare @today int
declare @week nvarchar(3)
set @today=3
set @week= case
     when @today=1 then '星期一'
     when @today=2 then '星期二'
     when @today=3 then '星期三'
     when @today=4 then '星期四'
     when @today=5 then '星期五'
     when @today=6 then '星期六'
     when @today=7 then '星期日'
     else '值错误'
end
print @week
