Description

I get the following error when I try to insert new row to a table that uses sequence object for identity.

<openjpa-1.0.1-r420667:592145 fatal store error> org.apache.openjpa.persistence.RollbackException: [SQL0029] INTO clause missing from embedded statement.

I have the following in persistence.xml

<property name="openjpa.jdbc.DBDictionary" value="db2"/>
<property name="openjpa.ConnectionDriverName" value="com.ibm.as400.access.AS400JDBCDriver"/>

I was able to fix the problem by modifying the following code.

I added:
nextSequenceQuery = "SELECT NEXTVAL FOR

{0}

FROM "
+ "SYSIBM.SYSDUMMY1";

to:
package: org.apache.openjpa.jdbc.sql
Class: DB2Dictionary
method: public void connectedConfiguration(Connection conn) throws SQLException

right after the code:
case db2ISeriesV5R4OrLater:

iSeries that have earlier versions might have the same problem.
If there is a problem, the same code should probably be added to "case db2ISeriesV5R3OrEarlier: " section.

I'm new to OpenJPA, so it will be great if some one can verify that the fix was done appropriately.

Thank you,
