Hi,

Is there a way that values can be queried when entered in 'dummy' fields and then validated against a LOV listing?

What do you call "dummy" fields? Non-database items? If so, then yes - you can use those values when creating ONETIME_WHERE block property (in SET_BLOCK_PROPERTY).

What do you mean by "validating" those values? Does it mean that you already stored invalid values into the database (as query retrieved them into a form)?

An example of the set block property you mentioned / more details....

Just saw another part of your initial response--- Here's more detail...i created a datablock...within that datablock i have 3 non-database item fields. There is also a button than brings up a list of values that i can select to populate these fields and then i can query. A post query trigger was created at the datablock level to return the actual values. However, i would also like to enter values in these fields that would validate against the listing from the LOV so as to have an alternative to perform a query. As such the query can be done both ways...

Thanks

SET_BLOCK_PROPERTY is described in Forms Help - open it and read what it says. Try to do it yourself. If you don't succeed, come back here, post what you did and someone will assist.

As of the rest of your question: although you can do it that way, it doesn't mean that you should do it that way. Why making thins complicated, if you can have them simple? Use as much of Forms built-in capabilities as you can. Does Quote:

i would also like to enter values in these fields
mean that you'd want to perform INSERT operation through those non-database items? If so, that's possible as well - you'll have to create your own trigger (such as PRE-INSERT) which would use non-database items as a source for database items).

As LoV works on non-database items as well as on database items, I'm not sure what is the problem regarding LoVs ...
