MS SQL 2008 - Update multiple rows with different values from spreadsheet

I have a table with about 350K rows in it and need to update about 45K with data that is in an excel spreadsheet.  The table to update is called "storage".  Fields mappings are as follows:
SHEET               STORAGE
receiptdate      sig_date
fromdate          Datefrom
todate               Dateto
alpha_from      contrfrom
aplha_to           contrto
main_desc       desc

the "where" indicator is a field common to both the spreadsheet and the table, tempid = tempid

The syntax I posted was intended for tables existing in database. I'd suggest you use the data import/export wizard to import the Excel sheet into a new table in your database, then run the update query as described above and finally drop the table containing the spreadsheet data.

If you want to just link the spreadsheet data, you could do that in MSAccess, by using a linked tablesfor the SQL Server table and linking the spreadsheet, but fastest and most robust method is to import the spreadsheet data into MSSQL first. You can import it to your tempdb instead of your production db if you prefer.

update storage
set sig_date =receiptdate, 
DateFrom=fromdate, 
DateTo=todate, 
contrfrom=alpha_from,
contrto=alpha_to,
desc=main_desc
From storage inner join sheet on storage.tempid=sheet.tempid

the question was almost the answer, I hope you can see the similarity

table to update is called "storage".  Fields mappings are as follows:
SHEET               STORAGE
receiptdate      sig_date
fromdate          Datefrom
todate               Dateto
alpha_from      contrfrom
aplha_to           contrto
main_desc       desc


the "where" indicator is a field common to both the spreadsheet and the table, tempid = tempid

hence you may not need to ask a similar question in future :)
no points please

I understand.  I guess I need to know how to "join" the excel spreadsheet.  Do I direct the join to the folder the spreadsheet is in?

Further thought: If you're doing this regularly, you might want to consider defining a package for it in SQL Server Integration Services (SSIS).
