问题描述

大家好

我创建了此表

Hi all

I created this table

a | b | c |  total  | evaluation  
1 | 2 | 3 |    6    | 
5 | 2 | 8 |    15   |      



--------------> 合计"列是求和(a + b + c)的结果

我想检查总计"列上的约束
如果合计= 12组评估=''完美''
否则将评估设置为弱"



--------------> " Total" is computed column is result for sum (a+b+c)

I want to check constraint on Total column
if total = 12 set evaluation =''Perfect''
else set evaluation = ''weak''

推荐答案

ALTER PROCEDURE dbo.ManageLaborEval
	(
@a int,
@b int,
@c int
)

AS
BEGIN

	Declare @sum bigint;
	Set @sum = @a + @b + @c;

	Declare @Evaluation NVARCHAR(30);
	IF @sum = 12
	BEGIN
		Set @Evaluation = 'Perfect';
	END
	ELSE
	BEGIN
		Set @Evaluation = 'weak';
	END
		
	INSERT INTO Table1(a, b, c, total, evaluation) VALUES (@a,@b,@c, @sum, @Evaluation)

END
