Question

我正在尝试创建一个View，它从Logs（Registro tracto和registro Operador）绘制最后一个条目，对应于LoadOrder（Orden de carga）的行程（viaje）并显示每个'带有信息的加载顺序'{ {3}}

我已经勾画了下一个视图，但由于Sytaxis错误，我无法使其正常工作。

    `CREATE VIEW `OrdenEnCurso` AS
    SELECT OC.'NO_ORDEN_DE_CARGA' AS 'ORDEN DE CARGA'
        , OC.'ID_VIAJE' AS 'ID DE VIAJE'
        , RT.'TRACTO_ECO' AS 'TRACTO'
        , ROO.'NOMBRE' AS 'N.OPERADOR', 
        GF.S AS 'GASTOS FINANCIADOS'
    FROM 
    'ORDEN_DE _CARGA' AS OC 
    INNER JOIN (SELECT 'TRACTO_ECO','ID_VIAJE' FROM 'REGISTRO_TRACTO' GROUP BY 
  'ID_VIAJE' HAVING MAX('FECHAHORA') ) AS RT 
        ON OC.ID_VIAJE=RT.ID_VIAJE
    INNER JOIN (SELECT CONCAT_WS(',',O.AP_PAT,O.AP_MAT,O.NOMBRE) AS 'NOMBRE' 
  FROM 'OPERADOR' AS O 
        INNER JOIN (SELECT 'ID_VIAJE','NO_OPERADOR' FROM 'REGISTRO_OPERADOR' 
    GROUP BY 'ID_VIAJE' HAVING MAX('FECHAHORA') ) AS RO 
            ON RO.NO_OPERADOR=O.NO_OPERADOR) AS ROO
        ON OC.ID_VIAJE=ROO.ID_VIAJE
    INNER JOIN (SELECT 'OC',SUM(IMPORTE) AS S FROM 'GASTOS_F_CLIENTE' 
GROUP BY 
    'NO_ORDEN_DE_CARGA') AS GF ON OC.NO_ORDEN_DE_CARGA=GF.OC;

另外，正如您所看到的，我想将运算符名称与昏迷联系起来。最后总结客户将为每个LoadOrder支付额外费用。

错误代码：1064。您的SQL语法有错误;查看与您的MySQL服务器版本对应的手册，以便在''NO_ORDEN_DE_CARGA'AS'ORDEN DE CARGA'附近使用正确的语法，OC.'ID_VIAJE'AS'ID DE VIAJE'，R'在第2行0.000秒

您对使用刻度线和引号感到困惑

尝试此SQL语句

CREATE VIEW OrdenEnCurso AS
    SELECT OC.NO_ORDEN_DE_CARGA AS `ORDEN DE CARGA`,
        OC.ID_VIAJE AS `ID DE VIAJE`,
        RT.TRACTO_ECO AS TRACTO,
        ROO.NOMBRE AS `N.OPERADOR`, 
        GF.S AS `GASTOS FINANCIADOS`
    FROM ORDEN_DE_CARGA AS OC 
    INNER JOIN (
        SELECT TRACTO_ECO, ID_VIAJE
        FROM REGISTRO_TRACTO 
        GROUP BY ID_VIAJE
        HAVING MAX(FECHAHORA) 
        ) AS RT 
        ON OC.ID_VIAJE = RT.ID_VIAJE
    INNER JOIN (
            SELECT CONCAT_WS(`,`,O.AP_PAT,O.AP_MAT,O.NOMBRE) AS NOMBRE
            FROM OPERADOR AS O 
        INNER JOIN (
            SELECT ID_VIAJE, NO_OPERADOR 
            FROM REGISTRO_OPERADOR
            GROUP BY ID_VIAJE 
            HAVING MAX(FECHAHORA) 
            ) AS RO 
            ON RO.NO_OPERADOR=O.NO_OPERADOR
        ) AS ROO
        ON OC.ID_VIAJE=ROO.ID_VIAJE
    INNER JOIN (
        SELECT OC,SUM(IMPORTE) AS S 
        FROM GASTOS_F_CLIENTE
        GROUP BY NO_ORDEN_DE_CARGA
        ) AS GF 
        ON OC.NO_ORDEN_DE_CARGA=GF.OC;
