Question

我需要将create视图和存储过程放在一个sql文件中。另一个只执行存储过程的文件。我尝试了下面的方法，但它不起作用。我怎么能这样做？

第一档：

  <servlet-mapping>
    <servlet-name>VendorWebApplication</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>

第二档：

CREATE PROCEDURE usp_top10Products
AS

exec ('CREATE VIEW vw_top10Products as
    SELECT Top 10 p.productID, p.productName as Product_Name,    inv.quantitySold as Quantity_Sold,
           (inv.sellingPrice - inv.costPrice)*inv.quantitySold as Profit 
    FROM Product p JOIN
         Inventory inv
         ON p.productID = inv.productID
    ORDER BY Profit Desc')

BEGIN
select *
from vw_top10Products;
END
GO

Answer 1

避免在存储过程中创建视图。如果您只需打印SELECT，则只需执行CREATE PROCEDURE usp_top10Products AS SELECT Top 10 p.productID, p.productName as Product_Name, inv.quantitySold as Quantity_Sold, (inv.sellingPrice - inv.costPrice)*inv.quantitySold as Profit FROM Product p JOIN Inventory inv ON p.productID = inv.productID ORDER BY Profit Desc GO

before_action :set_post

private

def set_post
  @post = Post.find(params[:post_id])
end

在文件中的存储过程中创建视图
