Author: alain collet

I would like to connect from a Xquery (and not a java prog) on STYLUS

connexion XML file 1
<JDBCConnection name="Intranet">
<description>connection to Intranet</description>
<url>jdbc:mysql://localhost:3306:intranet?</url>
<user>root</user>
<password>passe</password>
</JDBCConnection>

connexion XML file 2
<JDBCConnection name="SPMT">
<description>connection to SPMT</description>
<url>jdbc:mysql://localhost:3306:SourcingProjectManagement?</url>
<user>root</user>
<password>passe</password>
</JDBCConnection>

main prog in XQUERY
<contacts>
{
let $contactsI := collection("Intranet.keymro_contacts")/keymro_contacts,
$contactsS := collection("SourcingProjectManagement.users2")/users2
for $contactI in $contactsI
let $NI := data($contactI/lastname),
$NS := $contactsS/*[UserName/text()=$NI],
$NS_ := if(string-length($NS) > 0) then $NS else "_"
order by $NI
return
<contactsIetS>
{$contactI/lastname}
<S>
{$NS_}
</S>
</contactsIetS>
}
</contacts>

I find problems on the resolution but i use specificaly xml datasources to specify the 2 differents data sources
I have try without success to use the map tool but ...

some idea ?

Hi Alain,

Do you get an error when trying to execute the query?

If you drop the database name from the collection argument does it works?

replace Intranet.keymro_contacts with keymro_contacts
replace SourcingProjectManagement.users2 with users2

Hope this helps

yes I have naturaly done that at the first step
in all cases i found the "XQURIResolver:resolvecollection ... not found in any JDBC collection"
There is some tables with the same names in the 2 data bases

It is why I am looking for solutions as DataDirect propose as ... using connexion xml files with more information to specify the JDBC connexion
see my doc attached to see the environnement and the error
Tks

more information on the issue ON STUDIO

______________________________
here the information from datadirect to satisfy the multiples databases pbs

DDXQJDBCConnection jc1 = new DDXQJDBCConnection();
jc1.setUrl("jdbc:xquery:sqlserver://server1:1433;databaseName=financial");
jc1.setName("stocks1");
DDXQJDBCConnection jc2 = new DDXQJDBCConnection();
jc2.setUrl("jdbc:xquery:oracle://server2:1521;SID=ORCL");
jc2.setName("stocks2");
DDXQDataSource ds = new DDXQDataSource();
ds.setDdxqJdbcConnection(new DDXQJDBCConnection[] {jc1, jc2});
XQConnection conn = ds.getConnection("myuserid", "mypswd");
Here's an example showing the same connection information configured in a DataDirect XQuery source configuration file:
...
<JDBCConnection name="stocks1">
<description>connection to stocks1 data</description>
<url>jdbc:xquery:sqlserver://localhost:1433;DatabaseName=financial</url>
<user>myuserid</user>
<password>mypswd</password>
...
<JDBCConnection name="stocks2">
<description>connection to stocks2 data</description>
<url>jdbc:xquery:oracle://localhost:1521;SID=ORCL</url>
<user>myuserid</user>
<password>mypswd</password>
...
To target the holdings table on server1, qualify the table name with the JDBC connection name stocks1 in addition to the catalog name and schema name:
collection('stocks1:joseph.holdings')
________________________________

Are studio and the datadirect approach related ?
I don't find how to make links between connexion file and studio environnement
Thks for help

Hi Alain,

Could you please contact us at stylus-field-report@progress.com?

Which Stylus Studio build are you running
(Help -> About -> Framework version)

In the firs example we saw two MySQL databases on the same server, in the second example Oracle and SQL Server.
Which database vendor you are trying to access in the same query?

The configuration file is an obsolete approach, Stylus Studio uses the XQJ API in order to configure the database connections.

Thank you

Thanks I will contact the support

My 2 MySQL connexion are related with my pb.
I use the latest version from STylus 2008 build 1050G.

The XML configuration file are a recent Datadirect example dealing with multiples databases pb (tables with same names).
