/**
|
||
|
* Creates and executes a SELECT query, selecting fields ($select) from four tables joined
|
||
|
* Use $mmmTable together with $firstTable, $secondTable or $thirdTable to select over two or three tables. Or use all four tables to select a full MMM-relation.
|
||
|
* The JOIN is done based on the MMM table, with MMM.first_uid <--> first_table.uid / MMM.second_uid <--> second_table.uid / MMM.third_uid <--> third_table.uid and the respective tablenames
|
||
|
* If you don't provide aliases, they will be automatically added as suffix "_mmm", "_first", "_second", "_third" as soon as one of the tablenames is used twice or more
|
||
|
* The function is very useful for selecting 3 way relations
|
||
|
*
|

|
* @param string Field list for SELECT
|

|
* @param string Tablename, MMM table
|

|
* @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!
|
||
|
* @param string Optional GROUP BY field(s), if none, supply blank string.
|
||
|
* @param string Optional ORDER BY field(s), if none, supply blank string.
