Sessions and security

For interacting with Tempus Serva you need a session

 Session session = SessionFactory.getSession(this);

All sessions need to be terminated after use (releasing DB connections etc.)

 session.close();

Constructing queryies

First of create a query object

 SolutionQuery myQuery = session.getSolutionQuery( "mynewsolution" );

A query is built much like an SQL query by appending different fields to be SELECT'ed

  myQuery.addSelectField("MYNUMBER");

Additionally WHERE components are added

  myQuery.addWhereCriterion("StatusID", "In progress");

Note that lookup values etc. will be translated silently.

Finally execute the query and return the results

 SolutionQueryResultSet records = myQuery.executeQuery();

Retrieve data

Data are extracted from the query resultset using a relative reference to the record number

 for( int i=0; i<3; i++ ) {
    String text = "Value nr " + i " = " + resultSet.getRecordValue( i, "MYVALUE" );
    System.out.println( text );  
 }

Code example

The following example shows how data is retrieved from af collection of templates and used to create a collection of records (with values copied from the template).

       int parentTemplateDataID = Parser.getInteger( c.fields.getElementByFieldName(thisKeyToParentTemplate).FieldValue );
       
       Session session = SessionFactory.getSession(this);
       try {
           
           //Get data
           SolutionQuery opsaetning = session.getSolutionQuery(templateSolutionName);
           for(int i=0; i<fieldsTemplate.size(); i++ )
               opsaetning.addSelectField(fieldsTemplate.get(i));
           opsaetning.addWhereCriterion(templateKeyToParentTemplate, parentTemplateDataID);
           SolutionQueryResultSet recordsToCopy = opsaetning.executeQuery();
           
           int recordCount = recordsToCopy.size();
           for( int i=0; i<recordCount; i++ ) {
               SolutionRecordNew instance = session.getSolutionRecordNew(instanceSolutionName);
               
               for(int fi=0; fi<fieldsTemplate.size(); fi++ ) {
                   String value = recordsToCopy.getRecordValue( i, fieldsTemplate.get(fi));
                   instance.setValue( fieldsInstance.get(fi), value );
               }
               instance.setValueInteger( instanceKeyToParent, c.DataID );
               if( ! Parser.isEmpty(instanceKeyToTemplate) )
               instance.setValueInteger( instanceKeyToTemplate, recordsToCopy.getReference(i) );
               
               instance.persistChanges();
           }
       }
       catch(Exception e) {
           e.printStackTrace();
       }
       finally {
           session.close();
       }
