[MonetDB-users] Possible wrong results when Querying

by LeonardF

Hi There, I have some problem with the row_number() over() function. Consider the following table: create table "table1" ("customer" varchar(40), "product" varchar(40), "price" double) insert into "table1" values ('cust1', 'p1', 100) insert into "table1" values ('cust1', 'p2', 200) insert into "table1" values ('cust1', 'p3', 150) insert into "table1" values ('cust2', 'p1', 300) insert into "table1" values ('cust2', 'p3', 200) The following query over this table: SELECT "customer", "product", "sumprice", (Row_number() OVER(PARTITION BY "customer" ORDER BY "sumprice")) as "rank" FROM ( SELECT "customer", "product", (Sum("price")) AS "sumprice" FROM "table1" GROUP BY "customer", "product") AS "temp" Returns: Customer product sumprice rank Cust1 p1 100 1 Cust1 p2 200 2 Cust1 p3 150 3 Cust2 p1 300 1 Cust2 p3 200 2 But doesn’t it suppose to return the following result set?: Customer product sumprice rank Cust1 p1 100 1 Cust1 p3 150 2 Cust1 p2 200 3 Cust2 p3 200 1 Cust2 p1 200 2 Thanks -- Leonard Forgge -- View this message in context: http://www.nabble.com/Possible-wrong-results-when-Querying-tp22821802p22821… Sent from the monetdb-users mailing list archive at Nabble.com.

[MonetDB-users] ODBC error (specified driver could not be loaded due to system error 126)

by fadk

I read that there was a bug like this before, but its been fixed. Its seems like installing ODBC drivers is a problem for windows. Can you assist with this ? I am running winXP using the MonetDB 32 installer. http://sourceforge.net/tracker/?func=detail&atid=482468&aid=1902879&group_i… Also, is it possible to only build the client (to use mapi) on winXP given that I have MonetDB installed. ? Thanks for your help. -- View this message in context: http://www.nabble.com/ODBC-error-%28specified-driver-could-not-be-loaded-du… Sent from the monetdb-users mailing list archive at Nabble.com.

[MonetDB-users] massive data loss on stop, start

by Matthew Jones

I added this information as a comment to bug *2825243* but I'm not sure if it's the same so I thought I'd post it here also to see about getting some feedback: I am experiencing widespread data corruption when restarting the May2009-SP1 MonetDB release also, but mine is much simpler. On 64-bit ubuntu: Linux dsvm01 2.6.24-23-server #1 SMP Wed Apr 1 22:14:30 UTC 2009 x86_64 GNU/Linux With a table defined as follows: CREATE TABLE "tablespace"."test_table" ( "col1" varchar(50), "col2" varchar(50), "col3" varchar(50), "col4" varchar(50), "col5" varchar(50), "col6" int, "col7" timestamp(7), "col8" int, "col9" int, "col10" int ); I imported 20998687 records into this table with all columns populated and ran a couple of queries to check the data: select count(*) from test_table ; [ 20998687 ] select count(*) from test_table where col1 = '' or col2 = '' or col3 = ''; [ 0 ] select max(col7), min(col7) from test_table ; [ 2009-07-25 14:17:15.538000, 2009-07-24 15:29:12.524000 ] During the time I loaded the data and ran these queries I did not restart the database, it had been up for about 3 days I then issued: monetdb stop db and monetdb start db and re-ran the queries: select count(*) from raw_plays ; [ 20998687 ] select count(*) from raw_plays where col1 = '' or col2 = '' or col3 = ''; [ 20852061 ] select max(col7), min(col7) from test_table ; [ 2009-07-25 14:17:15.538000, -1-01-01 00:00:00.000000 ] This is some serious data corruption, I've lost data in the vast majority of these records! 73, Matthew W.

[MonetDB-users] can not delete data

by Allen Zhang

Hi, We had such a weird issue here, we are using Feb2009-SuperBall package, we managed get our data into monetdb, but some how when we try to delete data, it reappears under single user or readonly mode. Here is what we did, we put database in normal mode without gdk_single_user and gdk_readonly in monetdb5.conf. Issue a delete sql statement in mclient, now we query the data, seem the data is gone, and then we stop the database server, and start it in readonly mode. Then query the data again, the data come back!!! Seems to us the monetdb did not sync the memory with disk. Any ideas? Allen
