Hi, I get an error message when I retrieve a MAL plan over JDBC after the 250th call to ResultSet.next(). The relevant part of the stack trace is: java.lang.AssertionError: block 0 should have been fetched by now :( at nl.cwi.monetdb.jdbc.MonetConnection$ResultSetResponse.getLine(MonetConnection.java:1585) at nl.cwi.monetdb.jdbc.MonetResultSet.absolute(MonetResultSet.java:194) at nl.cwi.monetdb.jdbc.MonetResultSet.relative(MonetResultSet.java:2149) at nl.cwi.monetdb.jdbc.MonetResultSet.next(MonetResultSet.java:2116) The call to EXPLAIN works in mclient and returns a MAL plan that is 402 lines long. I can reproduce the error when I try to create the plan via jdbcclient, except that it says that block 1 should have been fetched and the exporter stops after line 160 or so. However, other SQL queries that also produce more than 250 results work over JDBC. Not sure what the difference is, but these queries only return column of integers. I'm using the Aug2011-SP3 release on OS X 10.6.8. Please let me know if I should provide other information like the SQL query or the MAL plan. Cheers, Viktor
