IsDefined takes a string. But you'll want to do structKeyExists instead
anyway.

IIRC, blockFactor is only relevant on the Oracle drivers, and it refers
specifically to how Oracle expects to batch and return large recordsets. If
Oracle is allowed to spool out large recordsets without returning them in
blocks, it will often spin the DB server out of threads, which then
