Description
Doesn't work both in the newest Teiid and the 7.x version.
Not sure how critical this is. When setting the prefetch via JDBC and using FORWARD_ONLY result set [1] I am getting exceptions [2]. I run the query on oracle (select * from XYZ limit 11).
TeiidDataSource ds = new TeiidDataSource(); ds.setDatabaseName(vdb); ds.setUser("user"); ds.setPassword("user"); ds.setServerName(host); ds.setPortNumber(Integer.valueOf(port)); ds.setFetchSize(10); .... Statement statement = connection.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY);
[2]
