VFP 7 doc states the following


"Include NOFILTER to create a cursor that can be used in subsequent queries. In previous versions of Visual FoxPro, it was necessary to include an extra constant or expression as a filter to create a cursor that could be used in subsequent queries. For example, adding a logical true as a filter expression created a query that could be used in subsequent queries:

SELECT *, .T. FROM customers INTO CURSOR myquery
Including NOFILTER can reduce query performance because a temporary table is created on disk. The temporary table is deleted from disk when the cursor is closed. "

But it never seemed to be problem( at least in VFP6 ) and it is not a problem in VFP7 for

SELECT * FROM customers INTO CURSOR myquery
select * from myquery where cust_id = some_id into cursor myquery1

What is meant by "subsequent query" then ?

Thank you
