Jakarta Persistence (JPA) represents queries with two interfaces: the Query interface, which was the only query interface in JPA 1 , and the TypedQuery interface, which was introduced in JPA 2. The TypedQuery interface extends the Query interface. Use the Query interface primarily when the query

LEFT OUTER JOIN. Fixed GROUP BY DATE(...) - merging AM and PM into the same date.

Fixed a critical bug in extensive removal operations of large objects. Improved the performance of navigation through an inverse (mapped by) field if the owner field is indexed. Fixed a LEFT OUTER JOIN bug . Fixed a bug in parsing queries with parenthesis followed by NOT . Fixed a bug in running

Hello, we found another query bug: SELECT a FROM ArtifactImpl a LEFT OUTER JOIN a.tcSignal s  WHERE a.startStep.stepNumber = 0  AND (s.name IN ('In1') OR a.tcSignal IS NULL) With 2.7.6_b6 we get the expected three result objects. But with 2.8.0 we get only two result objects

Hello, we have an issue with following query which needs with objectdb-2.7.6_07 only 15 - 30 milli seconds, but since objectdb-2.7.6_08 the query needs round about 3000 ms. I added a database example in a ticket. SELECT a FROM ArtifactImpl a LEFT OUTER JOIN a.tcSignal s WHERE a.endStep.stepNumber = 2000 AND a.startStep.stepNumber
