Subject [jira] Created: (OPENJPA-530) Statement batching incorrectly re-arranged order of SQL statements organized by update managers

Statement batching incorrectly re-arranged order of SQL statements organized by update managers
-----------------------------------------------------------------------------------------------

                 Key: OPENJPA-530
                 URL: https://issues.apache.org/jira/browse/OPENJPA-530
             Project: OpenJPA
          Issue Type: Bug
          Components: jdbc
    Affects Versions: 1.1.0
            Reporter: Albert Lee
            Assignee: Albert Lee
             Fix For: 1.1.0


BatchingPreparedStatementManagerImpl implements the core SQL statement execution function
of the Statement Batching features. 

The current implementation of this class holds a cache that maps SQL prepared statements to
a collection of parameters of batched requests for that prepared statement. When update manager
finishes batching its requests, BatchingPreparedStatementManagerImpl.flush() method is called
to submit the batch elements in the cache to the jdbc driver.

Essentially, this implementation discards all the ordering of statements being dispatched
to the statement batching function by the update manager. This caused improper order of SQL
statements to be sent to the data store. As a result, the underlying database may throw exception
indicates the unexpected data condition. E.g. 

com.ibm.db2.jcc.b.SqlException: Error for batch element #2: DB2 SQL error: SQLCODE: -530,
SQLSTATE: 23503, SQLERRMC: LEEALBER.EMPBEAN.SQL080226132752530
SQL0530N: The insert or update value of the FOREIGN KEY constraint-name is not equal to any
value of the parent key of the parent table.
