我想更新表中的列,在其他表上进行连接,例如:

UPDATE table1 a 
INNER JOIN table2 b ON a.commonfield = b.[common field] 
SET a.CalculatedColumn= b.[Calculated Column]
WHERE 
    b.[common field]= a.commonfield
AND a.BatchNO = '110'

但它抱怨:

消息170,级别15,状态1,行2
第2行:'a'附近的语法不正确.

这有什么不对？

我必须更新一个字段,其值由3个表的连接返回.

例:

select
    im.itemid
    ,im.sku as iSku
    ,gm.SKU as GSKU
    ,mm.ManufacturerId as ManuId
    ,mm.ManufacturerName
    ,im.mf_item_number
    ,mm.ManufacturerID
from 
    item_master im, group_master gm, Manufacturer_Master mm 
where
    im.mf_item_number like 'STA%'
    and im.sku=gm.sku
    and gm.ManufacturerID = mm.ManufacturerID
    and gm.manufacturerID=34

我想更新mf_item_number表的字段值item_master与在上述条件中连接的其他值.

我怎样才能在MS SQL Server中执行此操作？
