5 - Compiled and released new jars: monetdb-jdbc-2.27.jar, monetdb-mcl-1.16.jar
6 and updated jdbcclient.jar

8 * Thu Oct 5 2017 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
9 - Corrected method Connection.prepareCall(). It used to return null.
10 Now it throws an SQLFeatureNotSupportedException to comply with the
11 JDBC specification.

14 - Added possibility to let the JDBC driver return columnType value
15 Types.VARCHAR instead of Types.CLOB in case the result column of a
16 ResultSet or parameter in a PreparedStatement is of data type 'clob'.
17 To enable this behavior provide it as JDBC connection URL property:
18 treat_clob_as_varchar=true
19 For example: jdbc:monetdb://localhost:50000/demo?treat_clob_as_varchar=true
20 See also:
21 https://www.monetdb.org/Documentation/Manuals/SQLreference/Programming/JDBC
22 This custom clob mapping informs generic JDBC programs to fetch clob
23 column values via method ResultSet.getString() instead of getClob()
24 and Clob.getCharacterStream() and next fetching from the stream.
25 As MonetDB server MAPI communication protocol does not support
26 streaming of parts of a CLOB value, the current implementation is to
27 send over the whole CLOB value as a string. Therefore there is no
28 performance gain when fetching those Clob values via getClob() and
29 getCharacterStream(). In fact it creates a lot of overhead (additional
30 objects and method calls) and triples the amount of needed Java Heap memory
31 for each Clob value!
32 With this connection property set, you can reduce this overhead when
33 working with clob column data from generic JDBC programs.

35 * Thu Sep 7 2017 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
36 - Implemented PreparedStatement methods setNCharacterStream(int, Reader)
37 and setNCharacterStream(int, Reader, long).
38
39 * Thu Aug 31 2017 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
40 - Corrected PreparedStatement methods setString(int, String)
41 and setObject(int, Object, ...) in case the target parameter
42 data type was json or inet or url or uuid. See also

45 * Thu Aug 24 2017 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
46 - Implemented PreparedStatement method setURL(int, URL).
47 - Implemented PreparedStatement method setNString(int, String).
48 - The MonetDB JDBC driver code and jdbcclient program are now compiled
49 without debug info and with optimise flag enabled.
50 The new jar files are now some 20% smaller in size.
51
52 * Thu Aug 17 2017 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
53 - Implemented ResultSet method getNCharacterStream().
54 - In class MonetClob implemented methods getCharacterStream()
55 and getCharacterStream(long pos, long length). Method
56 getCharacterStream() is called by DBeaver to fetch the Clob value.
57 It used to throw a SQLFeatureNotSupportedException with message:
58 "Operation getCharacterStream() currently not supported". This caused
59 DBeaver to log the exception and show NULL as the value on screen,
60 which is incorrect. This has been fixed.
