Limitation on the use of the UNIQUE keyword in a CREATE TABLE statment.
If several columns are included in a UNIQUE clause, then InstantDB
ensures that each column is individually unique. This deviates
from the ANSI SQL specification where the columns should be
collectively unique.
Doesn't understand the standard timstamp escape sequence.
Doesn't understand repeated single quotes '' or double quotes "" as
a single character.
Doesn't support REPEATABLE_READ and READ_COMMITTED transaction isolation levels.
Only supports a single active results set per statement - This is in accordance
with the JDBC specification. However some other drivers do support this.
