我有3个插入存储过程,每个SP在2个不同的表中插入数据

Table 1          Table 2                
idPerson         idProduct             
name             productName            
phoneNumber      productdescription     
FK-idProduct

对于表2,表1 SP的SP

create procedure test1                create procedure test2
WITH                                  WITH 
EXECUTE as caller                     EXECUTE as caller
AS                                    AS
declare                               declare

@idPerson int,                        @idProduct int,
@name varchar(20),                    @productName varchar(50),
@phone varchar(20)                    @productoDescription varchar(50)


  SET nocount on;                     SET nocount on;
    Begin                             Begin
      insert into table1(                insert into table2(
                idPerson,                          idProduct,
                name,                              productName,
                phone)                             productDescription)
          values(                            values(
                @idPerson,                         @idProduct,
                @name,                             @productName,
                @phone)                            @productDescription)
      end                               end

我需要从存储过程测试1调用存储过程测试2并将FK-ID插入表1中

我有一个sql查询,运行超快,大约一秒,当不使用变量,如:

WHERE id BETWEEN 5461094 and 5461097

但是当我有:

declare @firstId int
declare @lastId int

set @firstId = 5461094
set @lastId = 5461097

...
    WHERE id BETWEEN @firstId and @lastId

...查询运行速度很慢,仅在几分钟后完成.为什么会这样？我需要使用变量.我可以做任何改进以避免这种性能问题吗？
