MySQL错误1064但不是保留字

Question

我有以下 MySQL 查询

    SELECT REPLACE(book.title,'','') AS "item-name", REPLACE(inventory.sku,'','') AS "sku", REPLACE(IF(inventory.sku IN (SELECT sku FROM qty_skus) , (SELECT qty_skus.quantity FROM qty_skus WHERE qty_skus.sku = inventory.sku LIMIT 1), inventory.quantity),'','') AS "quantity",

我收到以下错误，但我不知道原因:

    [Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '))))),inventory.cost),'','') AS "Cost",                     REPLACE(concat(IFNULL(buyer_type.' at line 12

我查看了错误指示的保留字，但我没有将成本视为保留字。救命!!!

Answer 1

改变这个

    IF(inventory.commission_level = 1, IF(inventory.cost < ((follette_title.usedbuying_price *1.71) OR (amtext.price*1.71)),(max((follette_title.usedbuying_price*1.71) OR (amtext.price*1.71)),inventory.cost),
    (max((follette_title.usedbuying_price*1.37) OR (amtext.price*1.37) OR (nebraska.price *1.2) OR (tichenor.price *1.25))))))))),inventory.cost),'','') AS "Cost",

至

    IF(inventory.commission_level = 1, IF(inventory.cost < ((follette_title.usedbuying_price *1.71) OR  (amtext.price*1.71)),(max((follette_title.usedbuying_price*1.71) OR (amtext.price*1.71)),inventory.cost),
    (greatest((follette_title.usedbuying_price*1.37) ,(amtext.price*1.37) , (nebraska.price *1.2), (tichenor.price *1.25))))))))),inventory.cost),'','') AS "Cost",

你不能使用max(a或b或c)而是使用greatest(a,b,c)
