试试这样……

Update t1.Column1 = value 
from tbltemp as t1 
inner join tblUser as t2 on t2.ID = t1.UserID 
where t1.[column1]=value and t2.[Column1] = value;

UPDATE im
SET mf_item_number = gm.SKU --etc
FROM item_master im
JOIN group_master gm
    ON im.sku = gm.sku 
JOIN Manufacturer_Master mm
    ON gm.ManufacturerID = mm.ManufacturerID
WHERE im.mf_item_number like 'STA%' AND
      gm.manufacturerID = 34

为了说清楚…UPDATE子句可以引用FROM子句中指定的表别名。所以在这种情况下im是有效的

通用的例子

UPDATE A
SET foo = B.bar
FROM TableA A
JOIN TableB B
    ON A.col1 = B.colx
WHERE ...

在SQL中使用连接查询进行更新是非常简单的，你可以不使用FROM子句进行更新。这里有一个例子:

    UPDATE customer_table c 

      JOIN  
          employee_table e
          ON c.city_id = e.city_id  
      JOIN 
          anyother_ table a
          ON a.someID = e.someID

    SET c.active = "Yes"

    WHERE c.city = "New york";

你可以在update语句中使用"FROM "子句指定用于确定如何更新以及更新内容的其他表，如下所示:

update item_master
set mf_item_number = (some value)
from 
   group_master as gm
   join Manufacturar_Master as mm ON ........
where
 .... (your conditions here)

在WHERE子句中，需要提供将这些表绑定在一起的条件和连接操作。

最简单的方法之一是使用公共表表达式(因为你已经在SQL 2005上了):

with cte as (
select
    im.itemid
    ,im.sku as iSku
    ,gm.SKU as GSKU
    ,mm.ManufacturerId as ManuId
    ,mm.ManufacturerName
    ,im.mf_item_number
    ,mm.ManufacturerID
    , <your other field>
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)
update cte set mf_item_number = <your other field>

查询执行引擎将自行确定如何更新记录。

将其应用到MySQL中——UPDATE中没有FROM子句，但这是可行的:

UPDATE
    item_master im
    JOIN
    group_master gm ON im.sku=gm.sku 
    JOIN
    Manufacturer_Master mm ON gm.ManufacturerID=mm.ManufacturerID
SET
    im.mf_item_number = gm.SKU --etc
WHERE
    im.mf_item_number like 'STA%'
    AND
    gm.manufacturerID=34
