Hi User-list!
I am experiencing segfault monetdb crash, platform:
CentOS Linux release 7.1.1503 (Core)
3.10.0-229.1.2.el7.x86_64 #1 SMP Fri Mar 27 03:04:26 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Table:
CREATE TABLE "marketdata"."quotes" (
"id" INTEGER NOT NULL DEFAULT next value for "marketdata"."seq_6391",
"qtime" TIMESTAMP WITH TIME ZONE NOT NULL,
"sdate" TIMESTAMP WITH TIME ZONE,
"sym" VARCHAR(10) NOT NULL,
"cur" VARCHAR(10) NOT NULL,
"open" DOUBLE NOT NULL,
"high" DOUBLE NOT NULL,
"low" DOUBLE NOT NULL,
"close" DOUBLE NOT NULL,
"volume" DOUBLE,
CONSTRAINT "quotes_id_pkey" PRIMARY KEY ("id")
);
SQL:
WITH cte(qtime, open, close, sdate, id, rnk) as (
select qtime, sdate, id, row_number() over (partition by sdate order by qtime asc) as rnk
from marketdata.quotes where sym='SPY'
) select * from cte where rnk=1;
~2M records loaded from csv.
Always segfault crashes monetdb daemon and DB became not repairable.
