Question

美好的一天我需要按Fecha列排序，但在使用order by时我不能，因为select中的union没有相同的列。你怎么能按这个字段排序Fecha。你能帮我解决一下吗？例如如下。

以下是我正在使用的查询。

        SELECT 'PESO:','VOLUMEN:','NO. PIEZAS:','ETD:','ETA:'

        UNION ALL 


        SELECT
        (SELECT ISNULL(Valor,'') FROM MovCampoExtra WHERE Modulo = 'VTAS' AND ID = Venta.ID AND CampoExtra = 'CEDIS0103') AS pesoBruto,
        (SELECT ISNULL(Valor,'') FROM MovCampoExtra WHERE Modulo = 'VTAS' AND ID = Venta.ID AND CampoExtra = 'CEDIS0121') AS volumen,
        (SELECT ISNULL(Valor,'') FROM MovCampoExtra WHERE Modulo = 'VTAS' AND ID = Venta.ID AND CampoExtra = 'CEDIS0102') AS cantidadUnidades,
         (SELECT CEDIS0120 FROM VentaCampoExtra WHERE ID = Venta.ID) AS ETD,
            (SELECT CEDIS0123 FROM VentaCampoExtra WHERE ID = Venta.ID) AS ETA
            FROM Venta 
            --Venta AS v
        INNER JOIN Cte AS c ON c.Cliente = Venta.Cliente
            INNER JOIN Usuario us On us.Usuario = Venta.Usuario
        WHERE

            @Origen=Venta.TMLICentroCosto AND
            Venta.Mov IN ('Instruccion EXPO', 'Instruccion IMPO','Instruc. Nacional')
            AND Venta.Empresa IN ('TM')
            AND Venta.ID is NOT NULL 
            AND Venta.Estatus NOT IN ('Cancelado')


         UNION ALL 


        SELECT 'FECHA:','HORA:','ACTIVIDADES:',' ',' '

        UNION ALL 

        SELECT

            Fecha = ISNULL(CONVERT(VARCHAR, mb.Fecha, 103),''), -- AS Fecha,
            Hora = ISNULL(CONVERT(VARCHAR, mb.Fecha, 108),''), -- AS Hora,

            Comentarios = ISNULL(mb.Evento2,''),
            '',
            ''


            FROM Venta 
            --Venta AS v
        INNER JOIN Cte AS c ON c.Cliente = Venta.Cliente
            LEFT OUTER JOIN MovBitacora AS mb ON mb.ID = Venta.ID
            INNER JOIN Usuario us On us.Usuario = Venta.Usuario

        WHERE

            @Origen=Venta.TMLICentroCosto AND
            Venta.Mov IN ('Instruccion EXPO', 'Instruccion IMPO','Instruc. Nacional')
            AND Venta.Empresa IN ('TM')
            AND Venta.ID is NOT NULL 
            AND Venta.Estatus NOT IN ('Cancelado')
            ORDER BY Fecha ASC          

        RETURN
        END

好吧首先呻吟出来，这是一种可怕的做事方式。您不应该从sql查询返回标头列，并将两个不相关的查询混合在一起。这应该是应用程序层调用的两个查询，它们也应该处理标题。

但是如果你出于某种神秘的原因必须这样做，你可以添加一个＆＃34;排序＆＃34;每个查询的列

Header 1 sortval = A
Peso query sortval = B + Peso
Header 2 sortval = C
Fecha query sortval = D + Fecha (in YYYYMMDD format)

然后在整个事物中添加一个大的选择来选择列（您需要在第一个标题选择中添加别名）并按sortval排序。

在具有不同列的联合中执行“由DESC或ASC订购”
