In this Support Note 3 examples of SQL statements are provided which are valid in Oracle 11g but which are not supported in TimesTen 11.2.2.

Finally, some comments are offered on the general question of how unsupported SQL syntaxes can be rewritten to be valid in TimesTen.
It is hoped that this Note will be expanded as we identify additional Oracle SQL syntax which does not work in TimesTen.
The following SQL statements which are valid in Oracle return parsing errors when run against TimesTen:
