[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-1981) Id generation strategy effects constraint checking timing
[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1981?page=all ]
Max Rydahl Andersen closed HHH-1981:
------------------------------------
Resolution: Rejected
naturally - that is because the id strategy requires an insert to occur immediatly into
the entity table to get the id.
Id generation strategy effects constraint checking timing
---------------------------------------------------------
Key: HHH-1981
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1981
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.1.3
Environment: Linux, PostgreSQL 8.1.4
Reporter: Emir Uner
Priority: Minor
The id generation strategy affects the timing of the constraints checking.
In our project, in a table there is a unique constraint for a column.
When we specify "identity" id generation strategy the unique constraint
viloation is detected as soon as we call saveOrUpdate.
But if we specify "native" id generation strategy, (possibly results in
"sequence" generator in PostgreSQL) the violation is not detected
until a manual flush call is made or transaction commited.
