The MonetDB team at CWI/MonetDB BV is pleased to announce the Dec2016-SP3 bugfix release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <http://www.monetdb.org/>. For details on this release, please see the release notes at <http://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <http://dev.monetdb.org/downloads/>. Dec 2016-SP3 bugfix release MonetDB Common * Fixed a bug when appending string bats that are fully duplicate eliminated. It could happend that the to-be-appended bat had an empty string at an offset and at that same offset in the to-be-appended-to bat there happened to be a (sequence of) NULL(s). Then this offset would be used, even though it might nog be the right offset for the empty string in the to-be-appended-to bat. This would result in multiple offsets for the empty string, breaking the promise of being duplicate eliminated. Bug Fixes * 6138: Weak duplicate elimination in string heaps > 64KB * 6183: ResultSet returns double quoted column name if name contains space characters * 6216: Assertion raised (sqlsmith) * 6219: Crash in rel_optimizer (sqlsmith) * 6227: Monetdb fails on remote tables * 6228: mclient crashes if real column is multiplied by it itself * 6229: ANALYZE, unexpected end of input * 6230: ANALYZE, syntax error * 6237: semijoin with empty right bat does not return immediately * 6242: Crash on rel_reduce_groupby_exps (sqlsmith) * 6243: Static optimization gives wrong result (1 + NULL = -127) * 6245: Nested query crashes all versions of MonetDB or gives wrong result starting from Dec2016-SP2 * 6246: update statements: references to a table do not bind to its alias * 6247: Type analysis issue (sqlsmith) * 6248: update statements: the semantic stage does not resolve the relation in the from clause * 6250: Assertion failure when querying a Blob column with order by DESC * 6251: Crash after adding an ordered index on sys.statistics column and querying sys.statistics * 6253: FITS Data Vaults does not work when using user/pw and other than sys schema name
