	Greetings, Is there any way to have an spi function return the result of a query, or 
to connect two tables in a view?  Specifically, I have a table of times and locations from an 
aerial flight, and a table of images from that flight, and I would like to select the images 
that occur within a specified area.  I had thought to join two tables in a view which I know 
that you can do with other databases but I cannot seem to determine how to do it in postgres.  
Alternately I had thought to use an spi function but I do not know how or if I can have it 
return the result of a select statement of more than one record.  The database ins Postgresql 
6.5.1 on a Linux (RH 6) box.
	Any help would be appreciated.
	
	Collin Lynch.

Have you just tried joining the tables on your datetime field? Is
there a problem with table joins and your images (presumably large
objects)?

If the simple join doesn't work, then doing the same in a view
probably won't either. How about sending the query and the schema?
