I am using SQL 7 with an MS Access 2000 MDB front end, using bound forms
with ODBC linked tables. In one form, the user needs to be able to check a
box to select one or more records. This is accomplished with a local table
containing two fields: the primary key value of the SQL table and a boolean
field used for the check box.
Since the local table used to contain the boolean field is local to the MDB
file, the result is a heterogeneous join in the underlying form query, which
degrades performance. I would like to have the entire query be based on back
end SQL data. However, each user needs to be able to make a unique set of
selections, without other users' selections affecting theirs.
An idea I have is to port the selections table to the back end with an
additional field for machine name; create a view of the main table joined to
the selections table; link the view to the front end; and base the form on
the SQL: "Select * From MyView Where MachineName='MyMachine'".
However, I wonder if there's a better approach. Any ideas would be
appreciated.
Thanks,
Neil
