问题：

I have to update a field with a value which is returned by a join of 3 tables. 我必须更新一个值，该值由3个表的联接返回。

Example: 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

I want to update the mf_item_number field values of table item_master with some other value which is joined in the above condition. 我想用其他在上述条件下加入的值更新表item_master的mf_item_number字段值。

How can I do this in MS SQL Server? 如何在MS SQL Server中执行此操作？
