T-SQL流程控制语句：两个简单的求和练习

T-SQL流程控制语句

练习：用While循环求1~100的偶数和。

Declare @number smallint,@sum smallint

Set @number=1

Set @sum=0

While @number<=100

Begin

If @number%2=0

Begin

Set @sum=@sum+@number

End

Set @number=@number+ 1

End

Print '1到100之间偶数的和为'+str(@sum)

Go

练习：计算1~100之间所有能被3整除的数的个数和总和。

Declare @number smallint,@sum smallint,@countsmallint

Set @number=1

Set @sum=0

Set @count=0

While @number<=100

Begin

If @number%3=0

Begin

Set @count=@count+1

Set @sum=@sum+@number

End

Set @number=@number+ 1

End

Print '1到100之间能被3整除的数的个数为'+str(@count)

Print '1到100之间能被3整除的数的总和为'+str(@sum)
