Hi:We had an interesting problem today. We have an entity called ReviewerData which has a personId and fiscalYear compound primary key. It also has 3 more attributes, a CLOB field, a varchar2(4000) and an Integer attribute. All attributes except the CLOB are marked as a locking attribute (see attached image).
When we are updating the CLOB field and any of the other 2 attributes and call EC saveChanges, we are getting the error:
Expected a LOB count of 0 but could not fetch that many objects.The issues is that there are 2 SQL statements being generated by the Oracle plugin within 1 transaction:
UPDATE REVIEWER_DATA SET HAS_DONE_EXTERNAL_REVIEW = ?, REVIEW_QUALIFICATIONS = EMPTY_CLOB() WHERE (PERSON_ID = ? AND FISCAL_YEAR = ? AND DESCRIPTION_OF_WORK = ? AND HAS_DONE_EXTERNAL_REVIEW = ?) withBindings: 1:0, 2:97208, 3:2012, 4:"ABC", 5:1
SELECT t0.REVIEW_QUALIFICATIONS FROM REVIEWER_DATA t0 WHERE (t0.PERSON_ID = ? AND t0.FISCAL_YEAR = ? AND t0.DESCRIPTION_OF_WORK = ? AND t0.HAS_DONE_EXTERNAL_REVIEW = ?) FOR UPDATE withBindings: 1:97208, 2:2012, 3:"ABC", 4:1
The SELECT statement fails, causing the error above. If I don't have a compound PK, only have a single PK attribute (personId), the SELECT statement only has one column in the where clause and all works great:
SELECT t0.REVIEW_QUALIFICATIONS FROM REVIEWER_DATA t0 WHERE (t0.PERSON_ID = ?) FOR UPDATE withBindings: 1:97208
I believe there is a bug in how the SQL is being generated. In the where clause it should only use the 2 PK attributes rather than all the lock attributes.
My question is how can I fix this? Is it the Oracle plugin? Wonder has an Oracle plugin, should I try that out first?
Michael.
