                  AND chassis_option.module_id = chassis_option_item.module_id 
                  AND chassis_option.option_code = 
                      chassis_option_item.option_code

试试这个：

SELECT <list all columns>, group_concat(sku_num) sku_num
FROM tableName
GROUP BY <list all columns>

SQL Server

SELECT 
    <list all columns>, 
    STRING_AGG(sku_num, ',') WITHIN GROUP (ORDER BY sku_num) AS [sku_num]
FROM 
    tableName
GROUP BY 
    <list all columns>

P.S。 SELECT和GROUP BY中的列列表应相同。
