创建视图MySQL中的语法错误

我试图创建一个视图，从日志（Registro tracto和Registro Operador）中提取与LoadOrder（Orden de carga）的行程（viaje）相对应的最后一个条目，并显示每个“Load Order with info”

我已经绘制了下一个视图，但由于Sytaxis错误，我无法使其工作

    `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，正如你可能看到的，我想把操作员的名字和昏迷分开。最后加上客户将为每个LoadOrder额外支付的金额

错误代码：1064。您的SQL语法有错误；检查与您的MySQL服务器版本对应的手册，以了解在第2行0.000秒处“NO_ORDEN_DE_CARGA”作为“ORDEN DE CARGA”，OC“ID_VIAJE”作为“ID DE VIAJE”，R”附近使用的正确语法

您混淆了记号和引号的用法

试试这个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;

什么错误？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，了解使用“NO_ORDEN_DE_CARGA”作为“ORDEN DE CARGA”，OC“ID_VIAJE”作为“ID DE VIAJE”，R”在第2行0.000部分的正确语法。很多时候，我学习MySQL已经快一年了，但从那以后就没有练习过。
