Simple UPDATE Question

    I think this is an easy question, and will expose

    my expertise (well ok lack of expertise).

    I have two tables.  I'd like to update BalanceTable.Vendor

    with VendorCodeTable.Vendor.  So all the rows in the

    Vendor field will have 01.

    My attempt did not work, LOL.  I realize I could just do

    Set Vendor = '01'  ... this is an oversimpified example

    of something else I'm trying to do.

    UPDATE BalanceTable

    Set Vendor = VendorCodeTable.Vendor

    FROM BalanceTable

    BalanceTable:

    AcctNo     Balance     Vendor

    1001       100         NULL  

    1002       100         NULL

    1003       100         NULL

    VendorCodeTable:

    Vendor

    01

    Almost right

    UPDATE BalanceTable

    Set Vendor = VendorCodeTable.Vendor

    FROM VendorCodeTable

    You can optionally add a where clause after to do joins e.g.

    UPDATE BalanceTable

    Set Vendor = VendorCodeTable.Vendor

    FROM VendorCodeTable

    WHERE BalanceTable.Region=VenderCodeTable.Region
