     order_stockavailable_attributes.id, 
     order_stockavailable_attributes.of_id, 
     order_stockavailable_attributes.opap_stock, 
     order_category.ocat_name 
FROM order_product 
    LEFT JOIN order_category

La consulta se error givng, T

Table 'order_product' from one of the SELECTs cannot be used in global ORDER clause

he comprobado el manual de MySQL, pero estoy sin obtener ninguna pista, cualquier ayuda sería realmente genial.

Answer 1

 
SELECT * 
FROM (
    SELECT order_product.op_id, 
      order_product.ocat_id, 
      order_product.op_partnunber, 
      order_product.op_name, 
      order_product.op_upc, 
      order_product.op_desc, 
      order_stockavailable.osa_id, 
      order_stockavailable.of_id, 
      order_stockavailable.osa_stocka, 
      order_category.ocat_name 
    FROM 
     order_product 
     LEFT JOIN order_category 
     ON order_product.ocat_id = order_category.ocat_id 
     LEFT JOIN order_stockavailable 
     ON order_product.op_id = order_stockavailable.op_id 
    UNION 
    SELECT order_product.op_id, 
      order_product.ocat_id, 
      order_product.op_partnunber, 
      order_product.op_name, 
      order_product.op_upc, 
      order_product.op_desc, 
      order_stockavailable_attributes.id, 
      order_stockavailable_attributes.of_id, 
      order_stockavailable_attributes.opap_stock, 
      order_category.ocat_name 
    FROM order_product 
     LEFT JOIN order_category 
     ON order_product.ocat_id = order_category.ocat_id 
     LEFT JOIN order_stockavailable 
     ON order_product.op_id = order_stockavailable.op_id 
     LEFT JOIN order_stockavailable_attributes 
     ON order_product.op_id = order_stockavailable_attributes.op_id 
) t 
ORDER BY op_name 

Por cierto: no hay necesidad de poner los SELECT individuales de una unión en los soportes.

Answer 2

Trate

order by op_name 

en lugar de

ORDER BY order_product.op_name 

Answer 3

Prueba la siguiente sintaxis?

SELECT 
    x, y 
FROM 
(
    SELECT x, y FROM z 
    UNION 
    SELECT a, b FROM c 
) 
ORDER BY 
    x, y 

Answer 4

SELECT * 
FROM (SELECT order_product.op_id, 
     ... 
     FROM 
     ...) 
     UNION 
     (SELECT order_product.op_id, 
     ... 
     FROM order_product 
     ...) U 
ORDER BY op_name;
