通過特定的兩個名稱查找記錄mysql

Question

我想通過單列中的兩個特定名稱獲取記錄，但是此查詢對我不起作用，

SELECT * 
FROM orders_custom oc 
    INNER JOIN group_options go 
    ON oc.group_option_id = go.group_option_id 
    WHERE orderedProduct_id = '40476' 
        AND go.is_default = 1 
        AND oc.group_name = 'size' 
        AND oc.group_name = 'base'

編寫它的正確方法是什么？

Answer 1

試試這個查詢

SELECT * FROM orders_custom oc 
INNER JOIN group_options go ON oc.group_option_id = go.group_option_id 
WHERE orderedProduct_id = '40476' 
    AND go.is_default = 1 
    AND oc.group_name in ('size','base')

或者，您可以在OR子句中指定名稱條件

AND (oc.group_name = 'size' OR oc.group_name = 'base' OR ...)

Answer 2

最后一個oc.group_name應該使用OR或IN 。

Answer 3

您需要使用OR ，請參見下面的示例：

SELECT * FROM orders_custom oc 
INNER JOIN group_options go 
    ON oc.group_option_id = go.group_option_id 
WHERE orderedProduct_id = '40476' AND go.is_default = 1 AND (oc.group_name = 'size' OR oc.group_name = 'base')
