 [0] => SQL Error: Expression #3 of SELECT list is not in GROUP BY clause
 and contains nonaggregated column 'mythconverg.program.endtime' which is
 not functionally dependent on columns in GROUP BY clause; this is
 incompatible with sql_mode=only_full_group_by [#1055]

 see: http://stackoverflow.com/questions/34115174/i-am-getting-an-error-in-
 mysql-related-to-only-full-group-by-when-executing-a-qu

 where it says: (#18)

 you can turn of the warning as explained in the other answers or you can
 understand what's happening and fix it.

 As of MySQL 5.7.5, the default SQL mode includes ONLY_FULL_GROUP_BY which
 means when you are grouping rows and then selecting something out of that
 groups, you need to explicitly say which row should that selection be made
 from. Mysql needs to know which row in the group you're looking for, which
 gives you two options

 Mysql needs to know which row in the group you're looking for, which gives
 you two options

     You can also add the column you want to the group statement group by
 rect.color, rect.value which can be what you want in some cases otherwise
 would return duplicate results with the same color which you may not want
     you could also use aggregate functions of mysql to indicate which row
 you are looking for inside the groups like AVG() MIN() MAX() complete list
