Announcement: New Jul2021-SP2 Bugfix release of MonetDB suite
by Sjoerd Mullender 21 Dec '21

21 Dec '21

The MonetDB team at MonetDB BV is pleased to announce the Jul2021-SP2 bugfix release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <https://www.monetdb.org/>. For details on this release, please see the release notes at <https://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <https://www.monetdb.org/downloads/>. Jul2021-SP2 Bugfix Release (11.41.13) Client Package * Dumping the database now also dumps the read-only and insert-only states of tables. MonetDB Common * Sometimes when the server was restarted, it wouldn't start anymore due to an error from BBPcheckbats. We finally found and fixed a (hopefully "the") cause of this problem. SQL Frontend * Number parsing for SQL was fixed. If a number was immediately followed by letters (i.e. without a space), the number was accepted and the alphanumeric string starting with the letter was interpreted as an alias (if aliases were allowed in that position). Bug Fixes * 7163: Multiple sql.mvc() invocations in the same query * 7167: sys.shutdown() problems * 7184: Insert into query blocks all other queries * 7185: GROUPING SETS on groups with aliases provided in the SELECT returns empty result * 7186: data files created with COPY SELECT .. INTO 'file.csv' fail to be loaded using COPY INTO .. FROM 'file.csv' when double quoted string data contains the field values delimiter character * 7191: [MonetDBe] monetdbe_cleanup_statement() with bound NULLs on variable-sized types bug * 7196: BATproject2: does not match always * 7198: Suboptimal query plan for query containing JSON access filter and two negative string comparisons * 7200: PRIMARY KEY unique constraint is violated with concurrent inserts * 7206: Python UDF fails when returning an empty table as a dictionary

Archiving of MonetDBLite repositories

Hello all, We would like to announce that MonetDBLite has been replaced by MonetDB/e. On January we will archive the following repositories: https://github.com/MonetDB/MonetDBLite-C https://github.com/MonetDB/MonetDBLite-R https://github.com/MonetDB/MonetDBLite-Python https://github.com/MonetDB/MonetDBLite-Java We've moved the best bits of MonetDBLite to MonetDB/e (i.e. MonetDB embedded), which we continue to develop and maintain. MonetDB/e is developed in the same codebase as the MonetDB server. This means that all new features and bug fixes land automatically in MonetDB/e. You can find bindings for Python (https://github.com/MonetDBSolutions/MonetDBe-Python) and Java (https://github.com/MonetDBSolutions/MonetDBe-Java) and we are working on bindings for R. You can also find a repository with code examples (https://github.com/MonetDBSolutions/monetdbe-examples).
