>From the documentation: "If the query condition does not contain the row id (and if no other index can be used), then all rows of the table are scanned." I guess that is a major important information when you trying to optimize your SQL, so it should be stated more visible and clearly. I am used to DB2/Oracle that performs this optimization, so I just took it for granted :)
H2 performance is really quite excellent, you just have to know to use the UNION optimization sometimes.
