/**
|
||
|
* Creates and executes a SELECT query, selecting fields ($select) from four tables joined
|
||
|
* Use $tripleTable together with $subjectTable, $predicateTable or $objectTable to select over two tables. Or use all four tables to select a full MMM-relation.
|
||
|
* The JOIN is done with triple.subject_uid <--> subject.uid / triple.predicate_uid <--> predicate.uid / triple.object_uid <--> object.uid
|
||
|
* The function is very useful for selecting MMM-relations like RDF triples
|

|
* @param string Field list for SELECT

* @param string Tablename, triple table, renamed to triple
|

* @param string Tablename, subject table, renamed to subject
|
||
|
* @param string Optional Tablename, predicate table, renamed to predicate
|
||
|
* @param string Optional Tablename, object table, renamed to object
|
||
|
* @param string Optional additional WHERE clauses put in the end of the query. NOTICE: You must escape values in this argument with $this->fullQuoteStr() yourself! DO NOT PUT IN GROUP BY, ORDER BY or LIMIT! You have to prepend 'AND ' to this parameter yourself!
|
||
|
* @param string Optional GROUP BY field(s), if none, supply blank string.
|
||
|
* @param string Optional ORDER BY field(s), if none, supply blank string.
|

* @param string Optional LIMIT value ([begin,]max), if none, supply blank string.
