Hello,

calling moveToInsertRow on a ResultSet returned by a prepared statement leads
to a NullPointerException:

Example code:

PreparedStatement p = c.prepareStatement(
"SELECT * FROM sampletable WHERE myid=?",
ResultSet.TYPE_FORWARD_ONLY,
ResultSet.CONCUR_UPDATABLE);

p.setInt(1,1);

ResultSet r = p.executeQuery();

r.moveToInsertRow();

Result:

Exception in thread "main" java.lang.NullPointerException
at org.postgresql.core.v3.SimpleQuery.toString(SimpleQuery.java:40)
at
org.postgresql.jdbc2.AbstractJdbc2ResultSet.parseQuery(AbstractJdbc2ResultSet.java:1656)
at
org.postgresql.jdbc2.AbstractJdbc2ResultSet.isUpdateable(AbstractJdbc2ResultSet.java:1516)

org.postgresql.jdbc2.AbstractJdbc2ResultSet.checkUpdateable(AbstractJdbc2ResultSet.java:2427)
at
org.postgresql.jdbc2.AbstractJdbc2ResultSet.moveToInsertRow(AbstractJdbc2ResultSet.java:868)

Driver Version: 8.0.309 JDBC3
PostgreSQL Version: 7.4.6

Best regards

Thanks for the report, fixed in CVS.

A workaround is to specify protocolVersion=2 in the connection URL, as
the V2 protocol code is correct (it looks like that change wasn't made
in both paths when I was originally writing this code)
