problem with Criteria.addSql() method

[Sy...@swisscom.com]

Hello,

I have another strange probem:

This code works fine:
----code----
String sqlQuery = "select distinct(workstationName) from Workstation w, WntWorkstation t where (w.workstationName like '%' or w.workstationName is NULL) order by w.workstationName";
Query query = QueryFactory.newQuery(Workstation.class, sqlQuery);

int numberOfWorkstations = 0;
numberOfWorkstations = broker.getCount(query);
----code----

But this code produces the error below:
----code----
Criteria crit = new Criteria();
crit.addSql(sqlQuery);

Query query = QueryFactory.newQuery(Workstation.class, crit);

int numberOfWorkstations = 0;
numberOfWorkstations = 
----code----

ERROR:
[org.apache.ojb.broker.accesslayer.JdbcAccess] DEBUG: executeCount : Query from class wocconfigdb400.data.Workstation where select distinct(workstationName) from Workstation w, WntWorkstation t where (w.workstationName like '%' or w.workstationName is NULL) order by w.workstationName

Is someone has an idea?

Thanks
