android - DISTINCT values with ", " divider in GROUP_CONCAT -

- 

group_concat(g_value,", ")

this gives me values [comma]+[space] divider

apple, orange, banana, apple, apple

group_concat(distinct g_value)

this gives me distinct values "," divider without space.

apple,orange,banana

how distinct values ", " divider?

apple, orange, banana

correct syntax is

group_concat( distinct g_value separator ', ')
