Question

我正在尝试创建SP以下，但是当我尝试执行这五个参数时，它要求输入最后3个输出参数。有人可以指出我正在搞乱的事情以及我如何解决它：

create PROCEDURE division_price_info_heatmap (@comp_id INT,
@compe_id INT, 
@Division_id INT out, 
@Division_name VARCHAR(20) out, 
@final_shipping_price DECIMAL(11,2) out)
AS
BEGIN
select T1.div, T1.div_n, (T1.price-T2.price)  as final_shipping_price from
(select  tcpi.division as div, td.division_name as div_n,
sum(tcpi.final_price_shipping) as price
from tb_competitor_product_info_new as tcpi 
inner join tb_division td on tcpi.division=td.division_id  
where competitor_id=@comp_id
group by tcpi.division, td.division_name
)   as T1,

(select  tcpi.division as div, td.division_name as div_n,
sum(tcpi.final_price_shipping) as price
from tb_competitor_product_info_new as tcpi 
inner join tb_division td on tcpi.division=td.division_id  
where competitor_id=@compe_id
group by tcpi.division, td.division_name
)   as T2
where T1.div=T2.div

END

执行命令： - division_price_info_heatmap 1,2

错误：

错误：过程或函数'division_price_info_heatmap'需要参数'@Division_id'，这是未提供的。 SQLState：S0004 ErrorCode：201

我正在使用mssql和squirrel UI。

还有一件事是我需要分配参数。

Answer 1

如果我没记错，MS SQL不会使用OUT关键字而是使用OUTPUT来存储过程，请尝试更改该部分，它应该可以正常工作。 See this for reference

当您调用该过程时，您必须提供将接收输出的变量，尽管在另一个答案中指出。

在旁注中看起来你实际上并没有返回任何东西，因为你从未向输出变量分配任何内容，但也许你在遗漏的代码中出现了这些内容。

此外，不需要围绕变量的括号，因此语句的开头应为：

CREATE PROCEDURE division_price_info_heatmap 
  @comp_id INT,
  @compe_id INT, 
  @Division_id INT OUTPUT, 
  @Division_name VARCHAR(20) OUTPUT, 
  @final_shipping_price DECIMAL(11,2) OUTPUT
AS

Answer 2

您传递了两个参数，该过程需要更多参数。执行命令应为：

DECLARE @Division_id INT, @Division_name VARCHAR(20), @final_shipping_price DECIMAL(11,2)
EXEC division_price_info_heatmap 1,2,@Division_id OUT,@Division_name OUT, @final_shipping_price OUT

或者您可以修改程序：

create PROCEDURE division_price_info_heatmap (@comp_id INT,
@compe_id INT, 
@Division_id INT = NULL out, 
@Division_name VARCHAR(20) = NULL out, 
@final_shipping_price DECIMAL(11,2) = NULL out)
AS
...

需要帮助构建存储过程
