Okay, I'm definitely not a SQL whiz, and I do not get the use of the "?" in the SQL statements. Can somebody explain this to me? For example:
SELECT * FROM table WHERE table.DateField <= ?
I can't find this anywhere except as a single character wildcard. How does that work when you're querying a date field?
Or what about this one?
"SELECT * FROM table WHERE table.field IN (?,?,?)" ; " " ; "|" ; "(A,B,C)" ) (I think I got that syntax right)
What the heck is that?
