Method Detail

setJoin

public void setJoin(IQuerySource sourceJoinedWith,
                    int joinType,
                    QualifierInfo joinQualifier)

Sets the join properties for this form. Example of joining the printer, computer and memory forms.

 SELECT fields FROM Printer J0
 INNER JOIN Computer J1 ON (qualifier) 
 INNER JOIN Memory J2 ON (qualifier)
  
 RegularQuery query = new RegularQuery();
 ...
 
 // order in which the sources are added determines the order of the join generation
  
 query.addFromSource(printerForm);
 query.addFromSource(computerForm);
 query.addFromSource(memoryForm);
 ... 
 
 // computer form sets a join with the printer form, not the other way around          
 
 computerForm.setJoin(printerForm, IQuerySource.AR_MULTI_SCHEMA_JOIN_INNER, joinQual1);
 memoryForm.setJoin(computerForm, IQuerySource.AR_MULTI_SCHEMA_JOIN_INNER, joinQual2);
