List the datasources of a query object

Here is how you can make a list of datasources from a query object. 

Query                query;

QueryBuildDataSource qbds;

Counter              child;

List                 listDataSources = new List(types::Class); 

ListEnumerator       le;

; 

query = new Query(QueryStr(CustBillOfExchangeJourUpdate)); 

for (child = 1; child <= query.dataSourceCount(); child++)

{ 

    listDataSources.addEnd(query.dataSourceNo(child));

} 

le = listDataSources.getEnumerator(); 

while (le.moveNext())

{ 

    qbds = le.current(); 

    info (TableId2Name(qbds.table()));

}
