[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? Thanks in advance, Alexandra ______________________________________________________ Click here to donate to the Hurricane Katrina relief effort. http://store.yahoo.com/redcross-donate3/

Hi, Sorry for missing the software information in last letter. I used MonetDB4-XQuery-Installer-x86_64-20110324 version, it seems to be the latest. If you have read my last letter, pls ignore followings. I am testing the performance of MonetDB/XQuery over large data. I use a HP xw8600 workstation, with Intel(R) Xeon(R) CPU X5482 3.20GHz, and 32GB RAM. I generate XMark data as large as 50GB, using standard XMark generator with 500 factor. When I tried to load it into database using "pf:add-doc", error message returned as following. ERROR = !ERROR: [shred_url]: 1 times inserted nil due to errors at tuples 0@0. !ERROR: [shred_url]: first error was: !ERROR: strPut: string heaps gets larger than 15GB. !ERROR: shredBAT_append_str: APPEND-STR[_prop_text]( !ERROR: catch fain deserves liking knee katharine easy hand helms daughter corn hire amaz plainness curtains staying excuse since tom walls thirty goodman twice corrections flesh behold woundl ess cargo royally zwagger nuncle season repair govern piercing sighs ounce arrest ganymede balthasar perjury !ERROR: ), BUNappend fails !ERROR: CMDshred_url: operation failed.

[MonetDB-users] DROP TABLE IF EXISTS <table>;
by Michael Sioutis 31 Mar '11

31 Mar '11

Hello, I want to prevent an SQLException from occurring for tables that do not exist in my database. For example: sql>DROP TABLE "locked"; SQLException:sql.catalog:DROP TABLE: no such table 'locked' It seems (and is documented) that there is no such thing like "IF EXISTS" in MonetDB. Is there a way to circumvent the SQLException? Mike

Xianmin, On Windows we only build with 32bits oids (even with 64bits pointers). When working with 32-bits offsets string heaps are restricted to 16GB. For large data, we recommend 64-bits linux. Then grab a oid64 rpm.

Hi, I am testing the performance of MonetDB/XQuery over large data. I use a HP xw8600 workstation, with Intel(R) Xeon(R) CPU X5482 3.20GHz, and 32GB RAM. I generate XMark data as large as 50GB, using standard XMark generator with 500 factor. When I tried to load it into database using "pf:add-doc", error message returned as following. ERROR = !ERROR: [shred_url]: 1 times inserted nil due to errors at tuples 0@0. !ERROR: [shred_url]: first error was: !ERROR: strPut: string heaps gets larger than 15GB. !ERROR: shredBAT_append_str: APPEND-STR[_prop_text]( !ERROR: catch fain deserves liking knee katharine easy hand helms daughter corn hire amaz plainness curtains staying excuse since tom walls thirty goodman twice corrections flesh behold woundl ess cargo royally zwagger nuncle season repair govern piercing sighs ounce arrest ganymede balthasar perjury !ERROR: ), BUNappend fails !ERROR: CMDshred_url: operation failed. Timer 2633290.282 msec Can you help me? How can I fix it? Thanks a lot. -- Xianmin Liu

[MonetDB-users] DROP TABLE IF EXISTS <table>;

Hello, I want to prevent an SQLException from occurring for tables that do not exist in my database. For example: sql>DROP TABLE "locked"; SQLException:sql.catalog:DROP TABLE: no such table 'locked' It seems (and is documented) that there is no such thing like "IF EXISTS" in MonetDB. Is there a way to circumvent the SQLException? Mike
