Non Null BLOB is not Inserted Through Triggers When Using Java Persistence API
Last updated on NOVEMBER 13, 2017
Applies to:Oracle TopLink - Version 22.214.171.124.1 and later
Information in this document applies to any platform.
A table (TBL_BPM_SERVICES_MASTER ) is created in Oracle Database that contains a BLOB type column (service_data).
A trigger is defined on this table (TBL_BPM_SERVICES_MASTER ) so
that for any insert / update on a row , a copy of the inserted / updated row
is done to another similar table (TABLE TBL_BPM_SERVICES_MASTER_AU) with
a blob column (service_data).
An entity is mapping the table TBL_BPM_SERVICES_MASTER :
The problem occurs when persisting ServicesMaster entity with a non null BLOB :
the corresponding row is well inserted into TBL_BPM_SERVICES_MASTER table
with a non null blob column (service_data).
But the row inserted into the TBL_BPM_SERVICES_MASTER_AU table thanks to the trigger
has the corresponding blob column (service_data) empty.
The expected behaviour is that TBL_BPM_SERVICES_MASTER_AU contais a row with a non null blob
value as in TBL_BPM_SERVICES_MASTER.
The used Eclipselink version is 1.0.2 .
