When using an alias with a space in it for a column name in a report you get this error 'Date ASC LIMIT 100 OFFSET 0'

[signup@…]

Take the default Active Ticket report and modify it to add a space in the id column alias SELECT p.value AS color,

id AS ticket,

SELECT p.value AS color,

id AS 'ticket id',

Now execute the report and sort on the 'ticket id' column and you will get the following error

Report execution failed: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Date ASC LIMIT 100 OFFSET 0' at line 13")
