我需要删除旧记录并在项目事件发生变化时每天插入新记录。我正在尝试按位置获取每个项目的清单,而不是清算,并且能够每天更新它,所以我创建了一个表格来删除&插入:
Items_minus_liquidation(表名)
(存储INTEGER NULL,
存储B INTEGER NULL)
表A:
LOCATION EVENT ITEM
STORE A LIQUIDATION APPLE
STORE A SALE BANANA
STORE A SALE ORANGE
STORE A SALE PEAR
STORE A LIQUIDATION PEACH
STORE A SALE SPINACH
STORE A SALE TOMATO
STORE A LIQUIDATION CARROT
STORE A SALE BROCCOLI
STORE A SALE MUSHROOM
STORE B LIQUIDATION APPLE
STORE B SALE BANANA
STORE B SALE ORANGE
STORE B SALE PEAR
STORE B LIQUIDATION PEACH
STORE B SALE PLUM
STORE B SALE TOMATO
STORE B LIQUIDATION CARROT
STORE B SALE BROCCOLI
STORE B SALE MUSHROOM
以下是我要找的结果:
STORE_A STORE_B
BANANA BANANA
ORANGE ORANGE
PEAR PEAR
SPINACH NULL
NULL PLUM
TOMATO TOMATO
BROCCOLI BROCCOLI
MUSHROOM MUSHROOM
这是我目前的查询:
DELETE FROM DB.ITEMS_MINUS_LIQUIDATION;
INSERT INTO DB.ITEM_MINUS_LIQUIDATION
SELECT
A.PRODUCT AS STORE_A,
B.PRODUCT AS STORE_B
FROM
(
SELECT
ITEM AS PRODUCT
FROM TABLE_A
WHERE EVENT NOT IN ('LIQUIDATION')
AND LOCATION='STORE_A'
) A
FULL OUTER JOIN
(
SELECT
ITEM AS PRODUCT
FROM TABLE_A
WHERE EVENT NOT IN ('LIQUIDATION')
AND LOCATION='STORE_B'
) B
ON A.ITEM=B.ITEM
问题是INSERT命令运行并运行并运行而不提供任何结果。完整的外连接查询产生了我上面正在寻找的内容,因此我希望删除旧记录并使用完整外连接查询插入新记录。为什么insert命令无法正常工作?
