It is in the JDBC spec. For each function and JDBC type it clearly
states what is the SQL type to be sent. It clearly indicates that each
'?' corresponds to a single value of a standard SQL type.
Things like sending a series of values (1, 2, 3, 4, 5) or x'b4' are
hacks that explore bugs in a non-JDBC compliant driver.
