Question

我在SQL Server中有两个表，一个是[W_Data]，它将具有原始数据，另一个是[A_Ticket]，它将包含Product及其优先级和类型的计数。目前，此表通过Access中的以下查询进行更新。现在我计划创建一个存储过程来从[W_Data]更新[A_Ticket]，因为它们都是MS Access中的SQL Server链接表。请帮我创建一个存储过程来替换以下查询。

（有关此要求的更多背景信息，请参阅前面的问题here。）

由于对数据库结构知之甚少，它将是这样的：

create procedure _update_ticket
  @product varchar(max),
  @date datetime
as
begin
  update t set
    I_S1_O = (select count(*) from W_Data where [Priority] = 'S1' and [Type] <> 'R' and [A_Group] <> '1' and [C_Date]< @date and [Product] = @product), 
    I_S1_R = (select count(*) from W_Data where [Priority] = 'S1' and [Type] <> 'R' and [A_Group] <> '1' and [C_Date]>= @date and [Product] = @product), 
    I_S1_Re = (select count(*) from W_Data where [Priority] = 'S1' and [Type] <> 'R' and [R_Group] <> '1' and [R_Group] is not NULL and [Product] = @product), 
    .....
  from ATicket t
  where Product_Name = @product
end

修改要更新整个ATicket（假设其中存在列Product_Name）：

create procedure _update_ticket @date datetime as begin update t set I_S1_O = (select count(*) from W_Data w where [Priority] = 'S1' and [Type] <> 'R' and [A_Group] <> '1' and [C_Date]< @date and w.[Product_Name] = t.[Product_Name]), I_S1_R = (select count(*) from W_Data w where [Priority] = 'S1' and [Type] <> 'R' and [A_Group] <> '1' and [C_Date]>= @date and w.[Product_Name] = t.[Product_Name]), I_S1_Re = (select count(*) from W_Data w where [Priority] = 'S1' and [Type] <> 'R' and [R_Group] <> '1' and [R_Group] is not NULL and w.[Product_Name] = t.[Product_Name]), ..... from ATicket t end
