我使用MySQL 5.5,我有兩個表,inventory_items和menu_items。它們都有一個bin_number,它是一個字符串,而location_id是一個整數。兩個表的sql更新語句
menu_items
invetory_item_id | location_id | bin_number
inventory_items
id | location_id | bin_number
我想更新menu_items INVENTORY_ITEM_ID到inventory_items表,他們是在bin_number和LOCATION_ID平等的ID。我可以繼續通過每個這樣的:
update menu_items set inventory_item_id=(select id from inventory_items where
bin_number='7060' and location_id=37) where bin_number='7060' and location_id=37;
有沒有辦法說全部更新menu_items到了bin_number和LOCATION_ID是menu_items和inventory_items的一樣嗎?

對不起,我的問題措辭可能很差。我試圖刪除這些硬編碼的值。將mi.bin_number = ii.bin_number和mi.location = ii.location做最後的where語句? – timpone 2014-09-20 03:15:58
酷,thx - 看起來像它應該:)必須等待幾分鐘 – timpone 2014-09-20 03:17:50
