String |
autoAssignSequenceName
The global sequence name to use for autoassign simulation. |
boolean |
openjpa3GeneratedKeyNames
Flag to use OpenJPA 0.3 style naming for auto assign sequence name and trigger name for backwards compatibility. |
static String |
SELECT_HINT
|
boolean |
useSetFormOfUseForUnicode
If true, then OpenJPA will attempt to use the special OraclePreparedStatement.setFormOfUse method to configure statements that it detects are operating on unicode fields. |
boolean |
useTriggersForAutoAssign
If true, then simulate auto-assigned values in Oracle by using a trigger that inserts a sequence value into the primary key value when a row is inserted. |
