[MonetDB-users] XQuery API and XLink/XUpdate support
by Alexandra Mart�nez 27 Jun '24

27 Jun '24

Hello all, I was wondering if there is any documentation about the API for XQuery (i.e., how to write xqueries from a Java program). Also, I am interested in using some features of XLink and XUpdate on top of my XML database. Is support for any of these in progress?

[MonetDB-users] Possible wrong results when Querying
by LeonardF 10 Nov '09

10 Nov '09

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.

Hi, I have compiled the latest August build from CVS on windows. When I run mclient, I get this: server requires 'SHA512' hash, but client support was not compiled in I saw another thread regarding this before, but couldn't resolve the issue based on it. Please let me know what I might be doing wrong.

[MonetDB-users] Long query response time with 'in' statement
by mkurtulus 02 Sep '09

02 Sep '09

Hi, I'm trying to create a benchmark MonetDB vs Postgres and for many types of queries, MonetDB quite faster than Postgres.But there is an interesting result when i try a query which contains an 'in' statement.The response times are MonetDB - 58 sec Postgres - 3 sec for the query : select RFOADV_10.rfoadvsup as c0, sum((case when cabact___rfountide = 'NB_E' then cabactqte else 0 end)) as m0 from RFOADV as RFOADV_10, CABACT as CABACT where (cabact___rforefide = 'FHSJ' and cabact___rteprcide = 'CPTANA' and cabact___rtestdide = '100' and cabact___rfovsnide = '200805_001') and CABACT.cabact_c2rfodstide = RFOADV_10.rfoadvinf and RFOADV_10.rfoadvsup in ('5030', '5031', '5032', '5033', '5034', '5035', '5036', '5037', '5038') group by RFOADV_10.rfoadvsup i reform the query so that it can give the same result without 'in' : select RFOADV_10.rfoadvsup as c0, sum((case when cabact___rfountide = 'NB_E' then cabactqte else 0 end)) as m0 from RFOADV as RFOADV_10 join CABACT on (CABACT.cabact_c2rfodstide = RFOADV_10.rfoadvinf) join (select '5031' as pole UNION select '5032' as pole UNION select '5033' as pole UNION select '5034' as pole UNION select '5035' as pole UNION select '5036' as pole UNION select '5037' as pole UNION select '5038' as pole ) sub ON (RFOADV_10.rfoadvsup = sub.pole) where (cabact___rforefide = 'FHSJ' and cabact___rteprcide = 'CPTANA' and cabact___rtestdide = '100' and cabact___rfovsnide = '200805_001') group by RFOADV_10.rfoadvsup the response time for MonetDB decreases 100 times (0.6 sec). Do you have any idea about it ? I run both Monetdb and Postgres on a server with 10GB Ram and the tables have CABACT : 677000 RFOADV : 140000 rows.

[MonetDB-users] COPY...INTO with auto increment
by Matthew Jones 31 Aug '09

31 Aug '09

I noticed that COPY...INTO for bulk loading requires that all fields be present in the data file. Is there any way to use bulk loading and have it honor the auto increment column or at least not have to specify every column in the data file? 73, Matthew W. Jones (KI4ZIB) http://matburt.net

[MonetDB-users] Function overloading
by Alex Bo. 30 Aug '09

30 Aug '09

Hi, I am trying to create an overloaded iif function, so I created these custom functions: 1. create function iifnew(tv timestamp, fv timestamp, cond boolean) returns timestamp begin if cond then return tv; else return fv; end if; end 2. create function iifnew(tv int, fv int, cond boolean) returns int begin if cond then return tv; else return fv; end if; end 3. create function iifnew(tv string, fv string, cond boolean) returns string begin if cond then return tv; else return fv; end if; end But now, if I do something like this: update table1 set "Column1" = iifnew('hello1', 'hello2', ("Column2" = "Column3")) I get this: !SQLException:int:conversion of string 'hello1' failed Is this a bug in function overloading? I am running Feb2009 from CSV on Windows.

[MonetDB-users] tijah phrase search problem
by Roy Walter 27 Aug '09

27 Aug '09

The following query: tijah:queryall("//p[about(., 'drug treatment')]") returns a number of results from my sample document. Some of these results contain the phrase "drug misuse". The following query: tijah:queryall("//p[about(., 'drug misuse')]") returns zero results from the sample document, which is clearly incorrect since some results returned by the first query should be returned by the second. I have deleted and reloaded the sample document and I have recreated the tijah index and the result is consistently incorrect. Is this a bug? -- Roy
