-     *                                        Note: you can also use related model field names like you would any other
-     *                                        field name. eg:
-     *                                        array('Datetime.DTT_reg_limit'=>array('=','Datetime.DTT_sold',TRUE) could
-     *                                        be used if you were querying EEM_Tickets (because Datetime is directly related to tickets) Also, by default all the where conditions are AND'd together. To override this, add an array key 'OR' (or 'AND') and the array to be OR'd together eg: array('OR'=>array('TXN_ID' => 23 , 'TXN_timestamp__>' =>
-     *                                        345678912)) becomes SQL >> "...WHERE TXN_ID = 23 OR TXN_timestamp =
-     *                                        345678912...". Also, to negate an entire set of conditions, use 'NOT' as
-     *                                        an array key. eg: array('NOT'=>array('TXN_total' =>
-     *                                        50, 'TXN_paid'=>23) becomes SQL >> "...where ! (TXN_total =50 AND
-     *                                        TXN_paid =23) Note: the 'glue' used to join each condition will continue
-     *                                        to be what you last specified. IE, "AND"s by default, but if you had
-     *                                        previously specified to use ORs to join, ORs will continue to be used.
-     *                                        So, if you specify to use an "OR" to join conditions, it will continue to
-     *                                        "stick" until you specify an AND. eg
-     *                                        array('OR'=>array('NOT'=>array('TXN_total' => 50,

-     *                                        "...where ! (TXN_total =50 OR TXN_paid =23) AND TXN_ID=1 AND
-     *                                        STS_ID='TIN'" They can be nested indefinitely. eg:
-     *                                        array('OR'=>array('TXN_total' => 23, 'NOT'=> array( 'TXN_timestamp'=> 345678912, 'AND'=>array('TXN_paid' => 53, 'STS_ID' => 'TIN')))) becomes SQL >> "...WHERE TXN_total = 23 OR ! (TXN_timestamp = 345678912 OR (TXN_paid = 53 AND STS_ID = 'TIN'))..." GOTCHA: because this is an array, array keys must be unique, making it impossible to place two or more where conditions applying to the same field. eg: array('PAY_timestamp'=>array('>',$start_date),'PAY_timestamp'=>array('<',$end_date),'PAY_timestamp'=>array('!=',$special_date)), as PHP enforces that the array keys must be unique, thus removing the first two array entries with key 'PAY_timestamp'. becomes SQL >> "PAY_timestamp !=  4234232", ignoring the first two PAY_timestamp conditions). To overcome this, you can add a '*' character to the end of the field's name, followed by anything. These will be removed when generating the SQL string, but allow for the array keys to be unique. eg: you could rewrite the previous query as: array('PAY_timestamp'=>array('>',$start_date),'PAY_timestamp*1st'=>array('<',$end_date),'PAY_timestamp*2nd'=>array('!=',$special_date)) which correctly becomes SQL >>
-     *                                        "PAY_timestamp > 123412341 AND PAY_timestamp < 2354235235234 AND
-     *                                        PAY_timestamp != 1241234123" This can be applied to condition operators
-     *                                        too, eg:
-     *                                        array('OR'=>array('REG_ID'=>3,'Transaction.TXN_ID'=>23),'OR*whatever'=>array('Attendee.ATT_fname'=>'bob','Attendee.ATT_lname'=>'wilson')));
-     * @var mixed   $limit                    int|array    adds a limit to the query just like the SQL limit clause, so
-     *                                        limits of "23", "25,50", and array(23,42) are all valid would become SQL
-     *                                        "...LIMIT 23", "...LIMIT 25,50", and "...LIMIT 23,42" respectively.
-     *                                        Remember when you provide two numbers for the limit, the 1st number is
-     *                                        the OFFSET, the 2nd is the LIMIT
-     * @var array   $on_join_limit            allows the setting of a special select join with a internal limit so you
-     *                                        can do paging on one-to-many multi-table-joins. Send an array in the

-     *                                        'where' conditions, these fields can be on related models. Eg

To override this, add an array key 'OR' (or 'AND') and the array to be OR'd together eg: array('OR'=>array('TXN_ID' => 23 , 'TXN_timestamp__>' =>
+	 *                                        345678912)) becomes SQL >> "...WHERE TXN_ID = 23 OR TXN_timestamp =
+	 *                                        345678912...". Also, to negate an entire set of conditions, use 'NOT' as
+	 *                                        an array key. eg: array('NOT'=>array('TXN_total' =>

+	 *                                        TXN_paid =23) Note: the 'glue' used to join each condition will continue
+	 *                                        to be what you last specified. IE, "AND"s by default, but if you had
+	 *                                        previously specified to use ORs to join, ORs will continue to be used.
+	 *                                        So, if you specify to use an "OR" to join conditions, it will continue to
+	 *                                        "stick" until you specify an AND. eg
+	 *                                        array('OR'=>array('NOT'=>array('TXN_total' => 50,

+	 *                                        STS_ID='TIN'" They can be nested indefinitely. eg:
+	 *                                        array('OR'=>array('TXN_total' => 23, 'NOT'=> array( 'TXN_timestamp'=> 345678912, 'AND'=>array('TXN_paid' => 53, 'STS_ID' => 'TIN')))) becomes SQL >> "...WHERE TXN_total = 23 OR ! (TXN_timestamp = 345678912 OR (TXN_paid = 53 AND STS_ID = 'TIN'))..." GOTCHA: because this is an array, array keys must be unique, making it impossible to place two or more where conditions applying to the same field. eg: array('PAY_timestamp'=>array('>',$start_date),'PAY_timestamp'=>array('<',$end_date),'PAY_timestamp'=>array('!=',$special_date)), as PHP enforces that the array keys must be unique, thus removing the first two array entries with key 'PAY_timestamp'. becomes SQL >> "PAY_timestamp !=  4234232", ignoring the first two PAY_timestamp conditions). To overcome this, you can add a '*' character to the end of the field's name, followed by anything. These will be removed when generating the SQL string, but allow for the array keys to be unique. eg: you could rewrite the previous query as: array('PAY_timestamp'=>array('>',$start_date),'PAY_timestamp*1st'=>array('<',$end_date),'PAY_timestamp*2nd'=>array('!=',$special_date)) which correctly becomes SQL >>
+	 *                                        "PAY_timestamp > 123412341 AND PAY_timestamp < 2354235235234 AND
+	 *                                        PAY_timestamp != 1241234123" This can be applied to condition operators
+	 *                                        too, eg:
+	 *                                        array('OR'=>array('REG_ID'=>3,'Transaction.TXN_ID'=>23),'OR*whatever'=>array('Attendee.ATT_fname'=>'bob','Attendee.ATT_lname'=>'wilson')));
+	 * @var mixed   $limit                    int|array    adds a limit to the query just like the SQL limit clause, so
+	 *                                        limits of "23", "25,50", and array(23,42) are all valid would become SQL

+	 *                                        Remember when you provide two numbers for the limit, the 1st number is

+	 * @var array   $on_join_limit            allows the setting of a special select join with a internal limit so you
