Assuming both tables have an ID column, you could update the other table like:

<pre><code>update ot
set col1 = tmp.col1
. col2 = tmp.col2
from @tbcompanies tmp
join OtherTable ot
on ot.ID = tmp.ID
</code></pre>

If in addition to updating, you'd like to <code>insert</code> rows that do not exist, consider the <a href="http://technet.microsoft.com/en-us/library/bb510625.aspx" rel="nofollow">merge statement</a>:

<pre><code>; merge OtherTable as target
using #tmpcompanies as source
on target.id = source.id 
when not matched by target then
 insert (id, col1, col2) values (source.id, source.col1, source.col2)
when matched then
 update set col1 = source.col1, col2 = source.col2;
</code></pre>

blocks|key|236493|text|您不需要遍历任何内容，因为您使用的是SQL+Server2008，并且此版本支持MERGE语句。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|236494|看一下here。|236495|或者简单地使用带有from子句的update并连接这两个表。|236496|entityMap|0|LINK|mutability|MUTABLE|url|http://www.mssqltips.com/sqlservertip/1704/using-merge-in-sql-server-to-insert-update-and-delete-at-the-same-time/^0|14|5|0|3|4|0|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@$9|S|A|T|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|U|8|@]|D|@$9|V|A|W|1|X]]|E|$]]|$1|H|3|I|5|6|7|Y|8|@]|D|@]|E|$]]|$1|J|3|-4|5|6|7|Z|8|@]|D|@]|E|$]]]|K|$L|$5|M|N|O|E|$P|Q]]]]

You don't need to loop through anything, since you use SQL Server 2008 and this version supports the <code>MERGE</code> statement. 

Have a look <a href="http://www.mssqltips.com/sqlservertip/1704/using-merge-in-sql-server-to-insert-update-and-delete-at-the-same-time/" rel="nofollow">here</a>.

Or simply use update with a from clause and join the two tables.

blocks|key|465245|text|如果需要upsert功能，我强烈推荐使用Merge函数。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|465246|伪码|465247|+++merge+TargetTableName+target

If it's upsert functionality you need, I strongly recommend the <a href="http://technet.microsoft.com/en-us/library/bb510625.aspx" rel="nofollow">Merge</a> function. 

pseudo code 

<pre><code> merge TargetTableName target
 using #tbcompanies tmp on tmp.idfield=target.idfield

 when not matched then insert...........

I need to insert the data in a csv file in to a temporary table and insert some data for the corresponding id value in another table. I have created and inserted the data in to the csv file. For all the records in the csv file how can I loop through and insert dome data for the corresponding record in the other table.

<pre><code>CREATE TABLE #tbcompanies
(ID INT)
GO

BULK
INSERT #tbcompanies
FROM 'd:\ids.csv'
WITH
(
ROWTERMINATOR = '\n'
)

select * from #tbcompanies

drop table #tbcompanies
</code></pre>

Loop through a temporary table and insert to another table
