Question

我有以下SQL;

ALTER  PROCEDURE [dbo].[MyReport]
    @startdate  datetime,
    @enddate    datetime
AS
    /* Return the event plan (coming events) for a specific volunteer */
   declare @sd datetime
   declare @ed datetime

    /* Ensure that the start and end dates covert whole days */
    set @sd = convert(varchar(10),@startdate,120) + ' 00:00:00'
    set @ed = convert(varchar(10),@enddate,120) + ' 23:59:59'

    SELECT 
       E.EventID, E.EventDate, E.StartTime, E.StartLocation, E.EndTime, 
       E.EndLocation, E.Charged, E.Actual,E.ChargeRate, E.Cost, 
       E.Persons, E.Reason,
       C.ClientID, C.Address1, C.Address2,
       C.Town, C.County, C.Postcode, 
       C.InvoiceName, C.InvoiceAddress1, C.InvoiceAddress2,
       C.InvoiceTown, C.InvoiceCounty, C.InvoicePostCode,
       ISNULL(C.Surname, '') + ', ' + ISNULL(C.Forename, '') AS ClientSurnameForename
    FROM 
       vEvents E 
    INNER JOIN 
       vClients C ON E.ClientID = C.ClientID
    WHERE    
       (E.EventDate BETWEEN @sd AND @ed) 
       AND E.SchemeID = 4
    ORDER BY 
       c.Surname, c.Forename, E.EventDate, E.StartTime, E.EndTime

我需要对E.Charged列进行求和，以便在返回记录集之前检查客户端的数量是否大于0。我尝试过以下方法：

ALTER PROCEDURE [dbo].[MyReport]
    @startdate  datetime,
    @enddate    datetime
AS
    /* Return the event plan (coming events) for a specific volunteer */
    declare @sd datetime
    declare @ed datetime

    /* Ensure that the start and end dates covert whole days */
    set @sd = convert(varchar(10),@startdate,120) + ' 00:00:00'
    set @ed = convert(varchar(10),@enddate,120) + ' 23:59:59'

    SELECT 
        E.EventID, E.EventDate, E.StartTime, E.StartLocation, E.EndTime, 
        E.EndLocation, E.Charged, E.Actual,E.ChargeRate, E.Cost, 
        E.Persons, E.Reason,
        C.ClientID, C.Address1, C.Address2, C.Town, C.County, C.Postcode,
        C.InvoiceName, C.InvoiceAddress1, C.InvoiceAddress2, C.InvoiceTown,
        C.InvoiceCounty, C.InvoicePostCode,
        ISNULL(C.Surname, '') + ', ' + ISNULL(C.Forename, '') AS ClientSurnameForename
    FROM 
        vEvents E 
    INNER JOIN 
        vClients C ON E.ClientID = C.ClientID
    WHERE 
        vEvents.ClientID IN (SELECT vEvents.Charged 
                             FROM vEvents 
                             GROUP BY vEvents.ClientID, vEvents.charged 
                             HAVING SUM(vEvents.Charged) > 0) 
        AND (E.EventDate BETWEEN @sd AND @ed) 
        AND E.SchemeID = 4
    ORDER BY 
        c.Surname, c.Forename, E.EventDate, E.StartTime, E.EndTime

但我不断得到多部分标识符无法绑定＆＃39;。 TIA Andrew

Answer 1

尝试将查询的WHERE部分更改为以下内容：

WHERE 
    E.ClientID IN (SELECT vEvents.ClientID 
                         FROM vEvents 
                         GROUP BY vEvents.ClientID 
                         HAVING SUM(vEvents.Charged) > 0) 
    AND ...

Answer 2

也许：

ALTER PROCEDURE [dbo].[MyReport]
    @startdate  datetime,
    @enddate    datetime
AS
    /* Return the event plan (coming events) for a specific volunteer */
    declare @sd datetime
    declare @ed datetime

    /* Ensure that the start and end dates covert whole days */
    set @sd = convert(varchar(10),@startdate,120) + ' 00:00:00'
    set @ed = convert(varchar(10),@enddate,120) + ' 23:59:59'

    SELECT 
        E.EventID, E.EventDate, E.StartTime, E.StartLocation, E.EndTime, 
        E.EndLocation, E.Charged, E.Actual,E.ChargeRate, E.Cost, 
        E.Persons, E.Reason,
        C.ClientID, C.Address1, C.Address2, C.Town, C.County, C.Postcode,
        C.InvoiceName, C.InvoiceAddress1, C.InvoiceAddress2, C.InvoiceTown,
        C.InvoiceCounty, C.InvoicePostCode,
        ISNULL(C.Surname, '') + ', ' + ISNULL(C.Forename, '') AS ClientSurnameForename
    FROM 
        vEvents E 
    INNER JOIN 
        vClients C ON E.ClientID = C.ClientID
    INNER JOIN (SELECT ClientID, SUM(Charged) ch
                FROM vEvents 
                GROUP BY ClientID
                HAVING SUM(Charged) > 0) t
      ON t.ClientID = vEvents.ClientID
    WHERE (E.EventDate BETWEEN @sd AND @ed) 
        AND E.SchemeID = 4
    ORDER BY 
        c.Surname, c.Forename, E.EventDate, E.StartTime, E.EndTime

SQL仅在总和大于0时才选择所有记录
