I am trying to make query and make case insensitive grouping of results by a field. Here is what I tried, but it doesn't work.
Lower keyword after group by doesn't make any difference.
"SELECT " + MediaStore.Audio.Media.ARTIST + ", count(LOWER(" + MediaStore.Audio.Media.ARTIST +
")) FROM " + PlaylistDB.TABLE_ALL_TRACKS + " GROUP BY LOWER(" + MediaStore.Audio.Media.ARTIST
+") HAVING " + MediaStore.Audio.Media.ARTIST
+ " LIKE ? ORDER BY "+ MediaStore.Audio.Media.ARTIST + " COLLATE NOCASE ASC";
Also I tried COLLATE NOCASE. Also doesn't work.
"SELECT " + MediaStore.Audio.Media.ARTIST + ", count(LOWER(" + MediaStore.Audio.Media.ARTIST +
")) FROM " + PlaylistDB.TABLE_ALL_TRACKS + " GROUP BY LOWER(" + MediaStore.Audio.Media.ARTIST
+") HAVING " + MediaStore.Audio.Media.ARTIST
+ " LIKE ? ORDER BY "+ MediaStore.Audio.Media.ARTIST + " COLLATE NOCASE ASC";
Is there anything you can suggest me to get case insensitive grouping?
I fix the issue. The lower keyword works with group by fine. But my mistake was that some fields were with additional space at the end. So I fixed it by using the trim keyword. The code below works as I need
"SELECT " + MediaStore.Audio.Media.ARTIST + ", count(LOWER(TRIM(" + MediaStore.Audio.Media.ARTIST +
"))) FROM " + PlaylistDB.TABLE_ALL_TRACKS + " GROUP BY LOWER(TRIM(" + MediaStore.Audio.Media.ARTIST
+")) HAVING " + MediaStore.Audio.Media.ARTIST
+ " LIKE ? ORDER BY "+ MediaStore.Audio.Media.ARTIST + " COLLATE NOCASE ASC";
