Hi Wouter and Stefan,

Thanks so much for your replies.  I apologize for the simple XQuery error below:  I tried to clean up and test a simple example before posting to the list ...oops.  As you can tell, the error is the same even with a corrected sequence: "count((1,2,3,4))".

I've been using XQuery for about two years now, mostly with BDB XML daemonized within our own servers.  I found this project just the other day and it very much piqued my curiosity and got me a little excited after my ultimately disappointing experience with Oracle's product, their query planner in particular.  I'm very interested to see how this database handles XML/XQuery, performance-wise, specifically for analytical workloads on large data sets:  think analysis/reporting on billions of audit events.  But I have a number of projects with different needs where MonetDB might be valuable.

I am not a C developer (I'm a PHP/XML web services developer), but if there is anything I can do to help, please let me know.

Thanks - Gene Stevens

Hello Gene,

I think you might have found a bug in the PHP client. The PHP client might only have been tested with SQL and not with XQuery. When using the SQL language, a semi-colon may be automatically added at the end of a statement, but when using XQuery that should of course not be done.

However, you will get an error anyway with the current query. The error you should have gotten is:

error in function application: at (1,1-1,14): wrong number of arguments for function `fn:count' (expected 1, got 4) # halted in functions.c (check_fun_usage), line 361

You should change your query to something like: "count((1,2,3,4))" or "count(1 to 4)"

Greetings, Wouter

Hi everyone,

I am a new MonetDB user.  I am specifically interested in MonetDB's XQuery support with client access through PHP.

I currently get parsing errors when trying any kind of XQuery through the PHP module.  I'm wondering if this is a a bug in the client or if I am possibly doing something wrong.  E.g.:

#!/usr/bin/env php <?php $db = monetdb_connect('xquery', 'localhost', 50000, 'monetdb', 'monetdb') or die ("Failed to connect\n"); $query = 'count(1,2,3,4)'; $res = monetdb_query($query); ?>

Results in:

Warning: monetdb_query(): Query failed: parse error: syntax error, unexpected ;, expecting $end on line 1, column 15 (next token is `;') !parse error: XQuery parsing failed in /home/user/monet.php on line 6

.... for any variation of an XQuery.  I have tried the server from the Ubuntu repository as well as I've built it from source with the same results.

Here is my environment:

PHP 5.2.6-3ubuntu4.1 with Suhosin-Patch 0.9.6.2 (cli)  (built: Apr 23 2009 14:37:14) Ubuntu 9.04:  Linux ubuntu 2.6.28-11-server #42-Ubuntu SMP Fri Apr 17 02:45:36 UTC 2009 x86_64 GNU/Linux

Hello Gene, I had some more time to look at the issue. It seems that the PHP interface still does not produce the expected behavior when a query returns multiple results. This doesn't affect your query as your query only yields 1 result. In my opinion a different row should be available for each item in the sequence of results. An example: a query like "1 to 4" should return 4 rows with 1 column, containing 1, 2, 3, and 4 respectively. Currently it doesn't seem to do so. I added a test for this, so we can monitor the status through our testweb, but probably someone more familiar with the MonetDB/PHP interface code should have a look at how to fix this. Greetings, Wouter 2009/8/9 Gene Stevens :

Hi Wouter,

Thanks a bunch.  That fixed the error:

#!/usr/bin/env php <?php $db = monetdb_connect('xquery', 'localhost', 50000, 'monetdb', 'monetdb') or die ("Failed to connect\n"); $res = monetdb_query('<node>{ for $i in (1,2,3,4) return $i }</node>'); while ($row = monetdb_fetch_row($res)) {     var_dump($row); } ?>

....produces this result:

array(1) {   [0]=>   string(20) "<node>1 2 3 4</node>" }
