Hello, I am experimenting with in-memory row-based & column-based stores. For the row-based store I am using SQLite. For the column-based, I am proposing to use MonetDB. In this context, I would like to join the mailing list. I am working on Windows XP / 32 and would like to use MonetDB as a DLL. Regards, Yuva

[MonetDB-users] SQL Function to remove all alpha characters
by Venks 28 Jan '08

28 Jan '08

Hi, Does MonetDB has regular expression support in SQL? I am looking to remove all alpha characters in a column value and wondering if there is a better way to do so rather than removing one character at a time. Thanks, -Venks

Hello, Is it possible to change the schema for tables that have already been created and populated? I'd like to avoid having to fully recreate everything as the load process will likely take a few days at least. thank you, Travis Brady

[MonetDB-users] Problems with COPY INTO and CHAR(N) columns containing empty strings or all spaces
by Bob Ippolito 22 Jan '08

22 Jan '08

We've had problems with MonetDB SR5 using COPY INTO with data that may be the empty string or all spaces. We've been able to work around this by surrounding all of the values in our copy files with "quotes" (I read tablet.c to try and diagnose the issue and found that as a workaround). I'm not familiar enough with the source and build process yet to submit a patch. We are using '\t' as the separator and the fields that we've had problem with are CHAR(2) or CHAR(16) if that matters. -bob

[MonetDB-users] Optimal filesystem/platform choices for MonetDB?
by Bob Ippolito 22 Jan '08

22 Jan '08

We've started doing a big import of data into SR5 and I've noticed that it's creating *A LOT* of files. So far we've got about 620k files for 6.7 GB of bat. I expect that a full import should have at least 20 times what's imported so far. It seems that loading data is relatively slow compared to PostgreSQL (we're using COPY) and I'm guessing it's due to all of these files. Right now we're using ext3 on amd64 ubuntu linux. Should we be looking at other platforms? -bob

[MonetDB-users] Core dump on first connect by mclient in BUNinplace
by Bob Ippolito 22 Jan '08

22 Jan '08

So we've been testing out a big ETL and it crashed again, and now every time we start mserver5 it will seemingly start up ok but as soon as mclient connects it will crash. I've generated a core dump. The db farm is 3.6GB and the core dump is 15MB. I can send either to someone if they need it to look further into the issue. The platform is 2.6.20-15-generic (root@yellow) (gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4)) #2 SMP on amd64. It's running an unmodified SR5 superball that we compiled … [View More]ourselves. I tried looking at strace and the --debug option with all of the flags on but it didn't produce anything that looked very interesting. The backtrace is here: Core was generated by `//mochi/bin/mserver5 --dbname=mochiads_stats --dbinit=include sql; --dbfarm=/da'.
