But you MUST remember to send argument in GROUPBY
(NOT NULL
send).
You must give column name for distinct
.
Example:
Cursor cursor = db.query(true, YOUR_TABLE_NAME, new String[] { COLUMN_NAME_1 ,COLUMN_NAME_2, COLUMN_NAME_3 }, null, null, COLUMN_NAME_2, null, null, null);
true – distinct TRUE
COLUMN_NAME_2
– name column what you have be DISTINCT.
That’s works for me fine.
