Jerry,

Seems you want to have a static SQL statment that produces different results caused by the parameters.

One method is to construct the WHERE clause dynamicly.

cWhere= somewhere expression
SELECT * FROM mytable WHERE &cWhere

In local views you can use SELECT * FROM mytable WHERE &?cWhere, but be sure the cWhere variable is available whenever using REQUERY.

Regards,

Walter,
