Serious error in data recording of type numeric

by Luciano Sasso

Serious error in data recording of type numeric. Using the jdbc driver 2.8, recording both base OUT2014SP4 when JUL2015SP1, records normally. But when using any jdbc driver above 2.8, the recording is wrong, for example, the value 845 is recorded as 850. Is it a bug?

MonetDB concurrent commits exception

by Vijay Krishna

Hi, I am running a setup on MonetDB where in concurrent transactions take place. Everything works very fine but for a few transactions getting aborted due to SQLExceptions. I have set *auto commit to false* for all these transactions. I am getting frequent SQLExceptions with the message as *java.sql.SQLException: COMMIT: failed* But if I retry the same transaction, this works fine. Any idea on what would be the reason for frequent commit fails? When I set *auto commit to true* for the transactions, I get similarly frequent Exceptions but the message becomes *java.sql.SQLException: COMMIT: transaction is aborted because of concurrency conflicts* Is it like both the exception thrown be for the same cause? Any help much appreciated. Thanks in Advance. Vijayakrishna.P. Mobile : (+91) 9500402305.

Import bug on bug tracker

by andy.barlow＠datum360.com

Hello there I reported what I believe to be a bug in the import routines towards the end of September: https://www.monetdb.org/bugzilla/show_bug.cgi?id=3812#c0 <https://www.monetdb.org/bugzilla/show_bug.cgi?id=3812#c0> Below is a summary of the issue I encountered, I wasn’t sure if the bug tracker is live/active so trying on this mailing list. Of course, this may be expected behaviour (though I doubt it) in which case would be useful to know.

BigDecimal Bug in MonetDB JDBC Driver

by Søren Haagerup

Hello developers, I found a bug when using BigDecimals in prepared statements with MonetDB¹s JDBC driver. If I have a column of type DECIMAL(15,2) and insert a big decimal with the value 627000.00 through a PreparedStatement, it will turn out as 630000.00 in the DB, since the MonetDB JDBC driver currently mixes up "precision" and "scale", and rounds 627000.00 to a precision of 2 ciphers. I made a bugfix for it, and it can be seen here: https://github.com/shaagerup/monet-jdbc/commit/ ebc5e654dc28e3b56d4c4b610d3d339e675d6c2c I¹m sorry for not committing it directly to your repository, but since I am not a Mercurial user, I hope someone else will use this information to improve the official JDBC driver. Best regards Søren Haagerup

Crash in table.c

by 营营

Hi MonetDB Dev, I can import the data in Jul2015, but the latest code fails to import(Win7 64Bit). It crashes in table.c (I used the old version (Jul2015) of this file, there is no crash). To reproduce the crash: 1. execute bi_create_table.sql to create the table, 2. change the path of bi_data.txt in bi_copy_from_file.sql. 3. execute bi_copy_from_file.sql to copy data from file. 4. if server doesn't crash immediately, run #3 more times. Thanks Cline 从网易163邮箱发来的云附件 bi_copy_from_file.sql (109.03K, 2015年11月16日 17:11 到期) 下载 bi_create_table.sql (1.14K, 2015年11月16日 17:11 到期) 下载 bi_data.txt (50M, 2015年11月16日 17:11 到期) 下载
