Question

我试图获取inv.ServicePrice的总和而不使用sum和group by，但我的查询不起作用。

ALTER PROCEDURE [dbo].[ServicesDetailedReport] 

        @FromDate date= '01-Jun-2010',
        @ToDate date= null

AS
BEGIN
        Set @ToDate= case when @ToDate IS NULL then Convert(varchar(11), getdate(), 106) else @ToDate end

        Select inv.InvoiceNo, inv.EntryDateTime, s.ServiceName, c.VehicleRegNo, inv.ServicePrice, c.CustomerName, inv.fk_BookingID
        from dbo.[Services] s
        inner join invoices inv
        on inv.fk_ServiceID= s.ServiceID
        inner join customers c
        on c.CustomerID= inv.fk_CustomerID
        Cross join (Select SUM(inc.ServicePrice) as TotalCost from dbo.Invoices inc as TotalCost) t
        where Convert(varchar(11), inv.EntryDateTime, 106) between @FromDate and @ToDate



END

Msg 156, Level 15, State 1, Procedure ServicesDetailedReport, Line 23
    Incorrect syntax near the keyword 'as'.

Answer 1

这是你的问题：

from dbo.Invoices inc as TotalCost

SQL Server将隐式使用AS关键字对您的表进行别名。因此，您的查询实际上被视为如下：

from dbo.Invoices AS inc AS TotalCost
                  ^      ^
                  |      |
                  |      |
                  |      |

基本上，您将表格混叠两次，这是无效的语法。

所以这将更新并更正程序代码：

ALTER PROCEDURE dbo.ServicesDetailedReport
    @FromDate DATE = '01-Jun-2010',
    @ToDate DATE = NULL
AS
BEGIN
    SET @ToDate = ISNULL(@ToDate, GETDATE());

    SELECT inv.InvoiceNo, inv.EntryDateTime, s.ServiceName, c.VehicleRegNo, inv.ServicePrice, c.CustomerName, inv.fk_BookingID
    FROM dbo.services AS s
    INNER JOIN invoices AS inv
        ON inv.fk_ServiceID = s.ServiceID
    INNER JOIN customers AS c
        ON c.CustomerID = inv.fk_CustomerID
    CROSS JOIN (   SELECT SUM(inc.ServicePrice) AS TotalCost
                   FROM dbo.Invoices AS inc) AS t
    WHERE inv.EntryDateTime BETWEEN @FromDate AND @ToDate;
END;

另请注意，我使用简单的ISNULL()替换了您的case语句，并在查询中删除了冗余转换运算符，但不需要它们。

Answer 2

您使用两次别名，然后使用第一个别名
修复：

(Select SUM(inc.ServicePrice) as TotalCost from dbo.Invoices inc)

Answer 3

只需删除＆＃39; AS＆＃39;用于＆＃39;作为TotalCost＆＃39;在交叉加入

为什么我的查询中没有交叉加入工作？
