# ChangeLog file for monetdb-java # This file is updated with Maddlog * Thu Oct 8 2020 Martin van Dinther <martin.van.dinther@monetdbsolutions.com> - Improved performance of ResultSetMetaData methods isAutoIncrement(), getPrecision() and getScale() significant for columns of specific data types as in some cases no costly meta data query is executed anymore. - The connection properties treat_clob_as_varchar and treat_blob_as_binary are now set to true by default within the JDBC driver. This is done as it results by default in less memory usage, (much) faster response and better user experience for many generic JDBC applications (like SQuirreL SQL, DBeaver, etc) when fetching data from CLOB or BLOB result columns. See release.txt for more information and how you can turn it off to get the old JDBC driver behavior if you require it. * Wed Oct 7 2020 Martin van Dinther <martin.van.dinther@monetdbsolutions.com> - Added support for new Java 8 java.sql.Types: Types.TIME_WITH_TIMEZONE and Types.TIMESTAMP_WITH_TIMEZONE. * Wed Sep 23 2020 Martin van Dinther <martin.van.dinther@monetdbsolutions.com> - Updated JDBC driver to comply with JDBC 4.2 interface now we compile for Java 8. This includes: - adding 8 methods to MonetCallableStatement - adding 2 methods to MonetDatabaseMetaData - adding 3 methods to MonetPreparedStatement - adding 4 methods to MonetResultSet - adding 8 methods to MonetStatement - Corrected MonetDatabaseMetaData.getTypeInfo() - The LITERAL_PREFIX column now includes the required casting name for types: clob, inet, json, url, uuid and blob. - The SEARCHABLE column now returns typePredBasic instead of typeSearchable for type: blob. - The AUTO_INCREMENT column now returns false for types: hugeint, decimal, oid and wrd. * Thu Sep 10 2020 Martin van Dinther <martin.van.dinther@monetdbsolutions.com> - Removed support for deprecated MD5 encryption algorithm in MapiSocket. * Wed Sep 9 2020 Martin van Dinther <martin.van.dinther@monetdbsolutions.com> - Corrected Statement.executeBatch() method. It now implicitly clears the batch buffer, ready to accept new addBatch() calls without the need for an explicit clearBatch() call. See also https://www.monetdb.org/bugzilla/show_bug.cgi?id=6953 * Wed Feb 19 2020 Martin van Dinther <martin.van.dinther@monetdbsolutions.com> - Corrected the return value of getCatalogTerm() to "cat". * Wed Feb 12 2020 Martin van Dinther <martin.van.dinther@monetdbsolutions.com> - As Java 7 is no longer supported we now compile for Java 8 as the minimum required JVM version (profile compact2).
