// As of iOS 8.2 Apple updated Sqlite and broke queries that used to work pre iOS 8.2 like the select command in this test
|

// The pruppose of this test is to know when apple fixes this. Expected test behaivour is as follows.
|
|
// If iOS 8.2+ Test will pass as long as apple does not fix the bug
|
|
// If iOS < 8.2 Test will pass as it does work as expected
|
|
// If iOS 8.2+ and apple fixed bug 27864 test will fail and we will need to remove the fail check on lines 105 and 106
