Select unique records from multiple records based on max date I have table like below 

+----+----------+-----+-------------+--------+
| ID |   ADDR   | IND | update_Date | Sq_NBR |
+----+----------+-----+-------------+--------+
|  1 | PHYSICAL | Y   | 11-Oct      |   1293 |
|  1 | BILL     | Y   | 10-Oct      |   1357 |
|  1 | BILL     | N   | 10-Sep      |  13567 |
|  1 | PHYSICAL | Y   | 10-Oct      |   8403 |
|  1 | BILL     | Y   | 6-Oct       |    135 |
|  2 | PHYSICAL | Y   | 9-Oct       |   5333 |
|  2 | BILL     | N   | 8-Aug       |    657 |
|  2 | BILL     | Y   | 8-Oct       |   3673 |
|  2 | BILL     | Y   | 10-Oct      |   2574 |
|  3 | BILL     | Y   | 11-Oct      |  57923 |
|  3 | BILL     | Y   | 11-Oct      |  29384 |
+----+----------+-----+-------------+--------+


need to check below multiple conditions before populating the data


If record has a combination of duplicate id, addr and Ind, then select the max(update_date) from that record.
If record has a combination of duplicate id, addr, Ind and update_Date, select only one record from the duplicate records (It can be any record).


Below was the expected result.

Can anyone plug me some ideas to achieve this.

here is the sqlfiddle:  http://sqlfiddle.com/#!4/d0098/1

+----+----------+-----+-------------+--------+
| ID |   ADDR   | IND | Update_Date | Sq_NBR |
+----+----------+-----+-------------+--------+
|  1 | PHYSICAL | Y   | 11-Oct      |   1293 |
|  1 | BILL     | Y   | 10-Oct      |   1357 |
|  1 | BILL     | N   | 10-Sep      |  13567 |
|  2 | PHYSICAL | Y   | 9-Oct       |   5333 |
|  2 | BILL     | N   | 8-Aug       |    657 |
|  2 | BILL     | Y   | 10-Oct      |   2574 |
|  3 | BILL     | Y   | 11-Oct      |  29384 |
+----+----------+-----+-------------+--------+
For the first condition 


count() Over (Partition by id, addr, Ind)
max(update_date) Over (Partition by id, addr, Ind) 


For the secontd condition 


row_number Over (Partition by id, addr, Ind and update_Date)
