Multi-column update based on joined table
by Lee Hachadoorian 11 Aug '24

11 Aug '24

I need to update multiple columns (~250) from one table to another based on a two-column key. In Postgres I would write this using the FROM clause, but since MonetDB doesn't support the FROM clause, I've successfully updated one column with: UPDATE census.acs2010_5yr SET b07401001 = ( SELECT CAST(b07401001 AS int) FROM acs2010_5yr.tmp_seq0001 WHERE acs2010_5yr.stusab = tmp_seq0001.stusab AND acs2010_5yr.logrecno = tmp_seq0001.logrecno ); My question is whether there is any benefit to writing a multiple column update into a single UPDATE statement: UPDATE target_table SET column1 = (SELECT column1 FROM source_table WHERE target_table.key = source_table.key), column2 = (SELECT column2 FROM source_table WHERE target_table.key = source_table.key), ..., columnN = (SELECT columnN FROM source_table WHERE target_table.key = source_table.key); On Postgres I believe the multi-column update using a table join would only have to do the sequential scan of each table once, but with the necessity of sub-selects in MonetDB, what is the backend doing? Is it already doing an index scan once for each row in the single column case, then doing it once for each row * column in the multi-column case?

Announcement: New Dec2023-SP4 Bugfix release of MonetDB suite
by Sjoerd Mullender 09 Jul '24

09 Jul '24

The MonetDB Foundation is pleased to announce the Dec2023-SP4 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/release-notes/dec2023/>. As usual, the download location is <https://www.monetdb.org/downloads/>. ### MonetDB5 Server - The mserver5 program has a new option: --without-geom. If the server was compiled with geom support (or the geom module was installed in a binary distribution), this option allows the server to start without the geom module, so that it can proceed with a database that was created without geom. ### SQL Frontend - When sys.persist_unlogged is called for a table, it may return that zero rows were persisted. If this is because the call was done too early, i.e. the table was recently created and the write-ahead log where this was logged has not been processed yet, the call will request an immediate write-ahead log rotation. This means that the WAL will be processed as soon as possible and a new call to sys.persist_unlogged soon after will likely return a positive result. ### Bug Fixes - [7509](https://github.com/MonetDB/MonetDB/issues/7509): MonetDB Dec2023-SP2 crashes at `sql_init_subtype` - [7511](https://github.com/MonetDB/MonetDB/issues/7511): MonetDB Dec2023-SP2 crashes with the `PASSWORD_HASH` function - [7512](https://github.com/MonetDB/MonetDB/issues/7512): MonetDB Dec2023-SP2 crashes with the `GET_MERGE_TABLE_PARTITION_EXPRESSIONS` function - [7513](https://github.com/MonetDB/MonetDB/issues/7513): MonetDB Dec2023-SP2 crashes with the `GETHOST` function - [7518](https://github.com/MonetDB/MonetDB/issues/7518): mserver reports errors when starting if geom module is enabled but database was created without - [7526](https://github.com/MonetDB/MonetDB/issues/7526): deadlock, causing new connections to hang indefinitely - [7531](https://github.com/MonetDB/MonetDB/issues/7531): loading more than 2147483647 rows gives issue. - [7536](https://github.com/MonetDB/MonetDB/issues/7536): Truncated file when dumping a table from mclient into a gzipped file - [7537](https://github.com/MonetDB/MonetDB/issues/7537): MonetDB crashes with a SIGSEGV due to a null pointer dereference when using prepared statements - [7541](https://github.com/MonetDB/MonetDB/issues/7541): Unexpected result when using `LEVENSHTEIN` - [7546](https://github.com/MonetDB/MonetDB/issues/7546): monetdbd leaks file descriptors when starting mserver5.
