在mssql中将选择结果分配给存储过程中的变量？

Question

我有以下选择：

SELECT School_Type,COUNT(ID) from Schools where City_ID = 1 group by School_Type

我得到了结果：

10 | 3
20 | 4
30 | 14

我想把结果放在：

• 输入10到变量@ElementarySchools
• 输入20到变量@HighSchools
• 输入30到变量@ProfessionalSchools

并从存储过程中获取此结果。

我该怎么做？

Answer 1

这样的事情？ ：）

declare @val varchar(max) = ''
select @val = @val + rtrim(foryear) + ' | ' + RTRIM( COUNT(*)) + ',' from mytable
group by ForYear

select @val

Answer 2

使用像这样的表变量：

declare @tmp table (School_Type int, School_Count int)
insert into @tmp
SELECT School_Type,COUNT(ID) from Schools where City_ID = 1 group by School_Type

select @ElementarySchools=School_Count from @tmp where School_Type=10
select @HighSchools=School_Count from @tmp where School_Type=20
select @ProfessionalSchools=School_Count from @tmp where School_Type=30
