RELEASE NOTES MonetDB JDBC driver version 2.28 (Liberica/MCL-1.17) Release date: 2018-05-24 This JDBC driver is designed for use with MonetDB, a main-memory column-store RDBMS. For more information see https://www.monetdb.org/ The MonetDB JDBC connection URL format to use is: jdbc:monetdb://<hostname>[:<portnr>]/<databasename>[?<property>=<value>[&<property>=<value>]] Note: For a successful connection the database name part must be provided and be equal to the name of the database served by the mserver5 process running on the specified host and listening to the specified port number (default port is 50000). Supported connection properties are: user=<login name> password=<secret value> so_timeout=<time in milliseconds> hash=<SHA512, SHA384, SHA256, SHA1 and MD5> language=<sql or mal> default is: sql treat_blob_as_binary=true default is: false treat_clob_as_varchar=true default is: false debug=true default is: false logfile=<name of logfile> Multiple connection properties are separated by the & character. For example: jdbc:monetdb://localhost:41000/mydb?user=monetdb&password=monetdb&so_timeout=7000&treat_clob_as_varchar=true See also: https://www.monetdb.org/Documentation/Manuals/SQLreference/Programming/JDBC Note: as of Jul2015 release (monetdb-jdbc-2.17.jar) we compile all the java sources to target: Java 1.7 so you need a JRE/JDK JVM of version 1.7 or higher to use it. JDBC COMPLIANCE The MonetDB JDBC driver complies to JDBC 4.1 definition, see http://docs.oracle.com/javase/7/docs/technotes/guides/jdbc/index.html Within the current implementation not all functionalities of the JDBC interface are available. It is believed, however, that this implementation is rich enough to be suitable for a majority of application settings. Below a list of (un)supported features can be found. Please read this list if you intend to use this JDBC driver. If you feel some features are missing or have encountered an issue/bug, please let us know at our bugtracker: https://www.monetdb.org/bugzilla/ Currently implemented JDBC 4.1 interfaces include: * java.sql.Driver * java.sql.Connection The next features/methods are NOT implemented: - createArrayOf, createNClob, createStruct, createSQLXML - createStatement with result set holdability - prepareCall (CallableStatement is not supported) see also: https://www.monetdb.org/bugzilla/show_bug.cgi?id=6402 - prepareStatement with array of column indices or column names - setHoldability (close/hold cursors over commit is not configurable) NOTE: be sure to check for warnings after setting concurrencies or isolation levels; MonetDB currently does not support anything else but "fully serializable" transactions. * java.sql.DatabaseMetaData * java.sql.Statement The next features/methods are NOT implemented: - cancel (query execution cannot be terminated, once started) see also: https://www.monetdb.org/bugzilla/show_bug.cgi?id=6222 - execute with column indices or names - executeUpdate with column indices or names - setMaxFieldSize - setCursorName - setEscapeProcessing on * java.sql.PreparedStatement The next features/methods are NOT implemented: - setArray - setAsciiStream, setBinaryStream, setUnicodeStream - setBlob - setNClob - setRef, setRowId, setSQLXML * java.sql.ParameterMetaData * java.sql.ResultSet The next features/methods are NOT implemented: - getArray - getAsciiStream, getUnicodeStream - getNClob - getRef, getRowId, getSQLXML - All methods related to updateable result sets * java.sql.ResultSetMetaData * java.sql.SavePoint * java.sql.Wrapper * java.sql.Blob A simple implementation using a byte[] to store the whole BLOB The next features/methods are NOT implemented: - setBinaryStream * java.sql.Clob A simple implementation using a StringBuilder to store the whole CLOB The next features/methods are NOT implemented: - getAsciiStream - setAsciiStream - setCharacterStream * java.sql.SQLData implemented by class: nl.cwi.monetdb.jdbc.types.INET and by class: nl.cwi.monetdb.jdbc.types.URL * javax.sql.DataSource (not tested) The next java.sql.* interfaces are NOT implemented: * java.sql.Array * java.sql.CallableStatement (use Statement or PreparedStatement instead) see also: https://www.monetdb.org/bugzilla/show_bug.cgi?id=6402 * java.sql.NClob * java.sql.Ref * java.sql.Rowid * java.sql.SQLInput * java.sql.SQLOutput * java.sql.SQLXML * java.sql.Struct
