D.6.4.12. Changes in MySQL Connector/J 3.0.6 (18 February 2003)

Bugs fixed:

  • Backported 4.1 charset field info changes from Connector/J 3.1.

  • Fixed Statement.setMaxRows() to stop sending LIMIT type queries when not needed (performance).

  • Fixed DBMD.getTypeInfo() and DBMD.getColumns() returning different value for precision in TEXT and BLOB types.

  • Fixed SQLExceptions getting swallowed on initial connect.

  • Fixed ResultSetMetaData to return "" when catalog not known. Fixes NullPointerExceptions with Sun's CachedRowSet.

  • Allow ignoring of warning for “non transactional tables” during rollback (compliance/usability) by setting ignoreNonTxTables property to true.

  • Clean up Statement query/method mismatch tests (that is, INSERT not permitted with .executeQuery()).

  • Fixed ResultSetMetaData.isWritable() to return correct value.

  • More checks added in ResultSet traversal method to catch when in closed state.

  • Implemented Blob.setBytes(). You still need to pass the resultant Blob back into an updatable ResultSet or PreparedStatement to persist the changes, because MySQL does not support “locators”.

  • Add “window” of different NULL sorting behavior to DBMD.nullsAreSortedAtStart (4.0.2 to 4.0.10, true; otherwise, no).
