Try this way… It help you.

String sql = "select * from "
                + TABLE_NAME + " WHERE placeId = '" + placeId + "'"; 
        Cursor cursorinfo = null; 
        try {
            database = databaseHelper.getReadableDatabase();
            cursorinfo = database.rawQuery(sql, null);
        } catch (Exception ex) {
            ex.printStackTrace();
        }

if (cursorinfo.moveToFirst()) {
            try {
                ///Already Exist data..
            } finally {
                database.close();
                cursorinfo.close();
            }

        } else {
            database = databaseHelper.getWritableDatabase();
            try {
                database.insert(TABLE_NAME, "", values);
            } finally {
                database.close();
                cursorinfo.close();
            }
        }
