Question

我在这个sql语句中有错，我不知道为什么：

SELECT t1.id_servidor_virtual as id_servidor_virtual,
    t1.nombre_servidor as nombre_servidor, 
    t1.plantilla as plantilla, 
    (SELECT tt1.descripcion
        FROM sku_precios tt1
        WHERE tt1.id_sku_precio = 'VM --') as c_sv,
    t1.sv_pvp as c_sv_pvp,
    t1.sv_pvp_dist as c_sv_pvp_dist,
    (SELECT tt1.descripcion
        FROM sku_precios tt1
        WHERE tt1.id_sku_precio = 'VCPU --') as c_cpu,
    t1.cpu_cant as c_cpu_cant,
    t1.cpu_pvp as c_cpu_pvp,
    t1.cpu_pvp_dist as c_cpu_pvp_dist,
    (SELECT tt1.descripcion
        FROM sku_precios tt1
        WHERE tt1.id_sku_precio = 'RAM --') as c_ram,
    t1.ram_cant as c_ram_cant,
    t1.ram_pvp as c_ram_pvp,
    t1.ram_pvp_dist as c_ram_pvp_dist,
    aletras(t1.ram_cant) as c_ram_unidad,
    (SELECT tt1.descripcion
        FROM sku_precios tt1 
        WHERE tt1.id_sku_precio = 'HDSTD --') as c_hdd,
    t1.hdd_cant as c_hdd_cant,
    t1.hdd_pvp as c_hdd_pvp,
    t1.hdd_pvp_dist as c_hdd_pvp_dist,
    aletras(t1.hdd_cant) as c_hdd_unidad,
    (SELECT tt1.descripcion
        FROM sku_precios tt1
        WHERE tt1.id_sku_precio = 'IPP --') as c_ip,
==> (t1.ip_pvpt1.ip_polled_pvpt1.ip_custom_pvp) as c_ip_pvp, 
    (t1.ip_pvp_distt1.ip_polled_pvp_distt1.ip_custom_pvp_dist) as c_ip_pvp_dist, 
    t1.id_servidor_virtual as parent_id, 
    (SELECT COUNT(t2.id_servicio_adicional) 
        FROM servicios_adicionales t2 
        WHERE t2.id_servidor_virtual = t1.id_servidor_virtual) as cant_sa,
    DATE_FORMAT(t2.f_inicio_contrato, '%d-%m-%Y') as f_inicio_contrato, 
    DATE_FORMAT(t2.f_fin_contrato, '%d-%m-%Y') as f_fin_contrato, 
    (SELECT tt2.n_pedido 
        FROM servidores_virtuales tt1 
        INNER JOIN pedidos tt2 ON tt2.id_pedido = tt1.id_pedido 
        WHERE tt1.id_servidor_virtual = t2.id_pedido_actualizado) as n_pedido_actualizado, 
    (SELECT t3.descuento 
        FROM albaranes t3 
        WHERE t3.id_pedido = t1.id_pedido 
        AND t3.id_cuenta_emisora = 2) as descuento 
FROM servidores_virtuales t1 
LEFT OUTER JOIN pedidos t2 ON t2.id_pedido = t1.id_pedido 
WHERE t1.id_pedido = 230;

错误是：

错误] 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，以便在“.ip_custom_pvp”附近使用正确的语法作为c_ip_pvp，在第32行

第32行标有==>。

你可以帮助我吗？非常感谢

Answer 1

t1.ip_pvpt1.ip_polled_pvpt1.ip_custom_pvp

您确定不应该在其中包含其他字符，例如+或-符号吗？

在我看来，这是三个单独的列：

t1.ip_pvp   t1.ip_polled_pvp   t1.ip_custom_pvp

应该以其他方式连接，而不仅仅是删除它们之间的空白区域： - ）

顺便说一下，这不是唯一一次，只是我接受的第一次。以下一行中也有一个。

MySQL抱怨的原因是，您显然在填充对象名称中包含两个 schema.object个字符时违反.命名标准（因此三个而不是两个水平）。
