后期的，后期的

UPDATE table1
SET    COLUMN = value
FROM   table2,
       table3
WHERE  table1.column_id = table2.id
       AND table1.column_id = table3.id
       AND table1.COLUMN = value
       AND table2.COLUMN = value
       AND table3.COLUMN = value 

后期的，后期的

UPDATE table1
SET    COLUMN = value
FROM   table2,
       table3
WHERE  table1.column_id = table2.id
       AND table1.column_id = table3.id
       AND table1.COLUMN = value
       AND table2.COLUMN = value
       AND table3.COLUMN = value 

Teradata Aster提供了实现目标的另一种有趣方式：

MERGE INTO ud --what table should be updated
USING sale -- from what table/relation update info should be taken
ON ud.id = sale.udid --join condition
WHEN MATCHED THEN 
    UPDATE SET ud.assid = sale.assid; -- how to update

我认为排名靠前的SQL Server将适用于Sybase，因为它们都是T-SQL，但不幸的是不是。

对于Sybase，我发现更新需要在表本身而不是别名上：

update ud
set u.assid = s.assid
from ud u
    inner join sale s on
        u.id = s.udid

标准的SQL方法是

UPDATE ud
SET assid = (SELECT assid FROM sale s WHERE ud.id=s.id)

在SQL Server上，可以使用联接

UPDATE ud
SET assid = s.assid
FROM ud u
JOIN sale s ON u.id=s.id

对于使用MySQL 5.7的prestashop用户

UPDATE
    ps_stock_available sa
    INNER JOIN ps_shop s
        ON sa.id_shop = s.id_shop AND s.id_shop = 1
    INNER JOIN ps_order_detail od
        ON sa.id_product = od.product_id AND od.id_order = 22417
SET
    sa.physical_quantity = sa.quantity + sa.reserved_quantity

这是一个例子，但重点正如埃里克在这里所说https://stackoverflow.com/a/1293347/5864034

您需要在FIRST处添加UPDATE语句，其中包含要连接的所有表的完整地址，然后添加SET语句
