Hi
I have control block. In which user enters two values. Next is data block in which two items have property 'copy value from item' set to 'control block.item1' and 'control block.item2' resp. If thees items are made database items then in execute query will they be sent as parameters in addition to default where clause? if I check last query then query does not hv these parameters but the records returned are already filtered by control block items.

As far as I can tell, no parameters are used here.
I'd say that "copy value from item" property did the same job as if in a PRE-QUERY trigger you set:data_block.item1 := :control_block.item1;
:data_block.item2 := :control_block.item2; so that executing a query knows which records to return (or, something like entering search criteria into the data block manually).
