Hi Joel,

Have you considered using a parameterized view? This would eliminate your having to change the SQL SELECT "variables" for each iteration, and would also preclude the need to "open" the SQL table.

To accomplish this in the View Designer, select the Filter tab (items in this tab populate the WHERE clause of the SQL statement). Under the "Example" column, instead of a constant (ie, "MYVALUE"), use a variable name preceded by a question mark (ie, ?lcMyValue ).

Now, whenever you want a new set of records in the view, populate lcMyValue with your desired value and issue the command REQUERY( "MyViewName" ).

HTH.

If I just try to "open" the SQL table, it will download *ALL* of the table and can take MANY MANY minutes. SO my view just gets the ONE record I want, but to go to another record, I must close the view, change the select statement memory variables and open the table again. It is literally 100 times faster to use Foxpro on a copy of the SQL table, but I need to use teh real SQL data.
