Dear everyone, Recently,i am testing the performance of MonetDB. But I want to know the time of execution one sql. I type \t on CLI. and then it returns a execution time. But I found that the time include the print resultset time.I just only want to know the time of execution ,not include the print time. So please tell me what do i do? -----------------Best regards!

[Monetdb-developers] TPC-H Query-14
by Romulo Goncalves 15 Jul '10

Hello, I am running TPC-H in the default version, updated 1 minute ago. Compilation in Debug mode and I am running in my Desktop at CWI. I loaded TPC-H SF-10 without constraints. [goncalve@alviss queries]$ mclient -lsql < 14.sql MAPI = monetdb@localhost:55000 QUERY = select ERROR = !SQLException:convert:too many digits (20 > 19) #select * from optimizer_stats() stats; % .stats, .stats # table_name % rewrite, count # name % clob, int # type % 7, 1 # length [ "joinidx", 0 ] [goncalve@alviss queries]$ Why do I get an Exception when I got a result? Regards, Romulo

I just corrupted my database by deleting a column and a constraint. Could you link the changeset to the ticket so I can apply the patch manually? If you applied fix to Feb2010 branch, please link that changeset, as that's what I am running. Thanks, m

This changeset accientally contains changes to file sql/src/server/sql_parser.mx that should have gone into a seperate checking / changeset: " Refined my earlier fix "fixed (restored) order_by over union_all" (http://dev.monetdb.org/hg/MonetDB/rev/35ebc65eb74c): we now also (re-)allow ORDER BY over EXCEPT & UNION . Note. though, that (as also in Feb2010 and most probably earlier releases, MonetDB incorrectly ignores ORDER BY over UNION, EXCEPT & INTERSECT.

You must know the number of column horizontally. You can make tables of strings, obviously it will limit you in your options. Stefan

The error message obviously should disappear, so it doesn't matter it differs every time. (unless someone (perhaps even me) accidentially approved this as the correct output)

[Monetdb-developers] core file on assertion violation?
by Mark Bucciarelli 06 Jul '10

06 Jul '10

Hi, I'm debugging an assertion failure I'm seeing w/ Feb2010: rel_optimizer.c:3039: find_index: Assertion `list_length(exps) == list_length(es)' failed. But I can't find the core file. Shouldn't there be one? Running a small C program that calls abort() as the merovingian user does create a core file. Thanks, m

Jan, are this checkin to the Feb2010 branch (changeset 1e2808a8e416) and your other checkin to the Jun2010 branch (changeset cc8b3ce4c30a) meant for these branches, only, or should they also be propagated to (merged into) the Jun2010 branch (changeset 1e2808a8e416) and default branch (both changesets). In either case, do you take care of the respective merges (both doing and preventing the propagation require merging the heads) yourself, or do you prefer us to do them? Thanks!
