Lukas,
Take a look at the attached example. It does not use dataset parameters
but does use report parameters from a multiselect parameter. Look at
the script on the orderdetails dataset and see how the query is changed
using the report parameter.

Thanks Janson,
in the and I found a lot of similar solutions, eg:
http://www.birt-exchange.com/forum/designing-birt-reports/92 24-passing-dynamic-multiple-values-report-parameter-birt.htm l
http://download.eclipse.org/birt/downloads/examples/reports/ 2.1/querymod/querymod.html
but all of them don't escape parameters passing to the SQL query.
Finally I designed DataSet this way:
* set 'Query' as:
select * from repo.sumarizace_neefektivni_apl_tab(?,?,?,?,?,?,?,?,?)
* setup all params in the 'Parameters' tab. The one, that is a multi
value I set to type String, and to the 'Default value' tab I wrote this
code:
function formatListQueryParams(paramsArray) {
var queryStr="";
for (var index = 0; index < paramsArray.length; index++) {
queryStr = queryStr.concat(paramsArray[index] + ";");
}
queryStr = queryStr.substr(0, queryStr.length - 1);
return queryStr;
}
formatListQueryParams(reportContext.getParameterValue("app_names "));
* the others params I setup as a 'Linked To Report Parameter'
and on the Postges side I used the parameter this way:
b.apl_name NOT IN (select regexp_split_to_table($6,E';'))
