Hello everyone,
I have in a table the following data. As you can see I have repeating SERIAL number, but with different UNIT number. I would like to list only one SERIAL number with the LOWEST UNIT number. i.e. the result of my query should be as follow:
EQUIPMENT
+-----------+------------------+-----------------------+------------+
| ID | SERIAL | TAG | UNIT |
+-----------+------------------+-----------------------+------------+
| 0001 | AAAABBBB001 | ABCDEFGH-0001 | 100 |
+-----------+------------------+-----------------------+------------+
| 0001 | AAAABBBB001 | ABCDEFGH-0001 | 110 |
+-----------+------------------+-----------------------+------------+
| 0001 | CCCCBBBB002 | ABCDEFGH-0001 | 500 |
+-----------+------------------+-----------------------+------------+
| 0001 | CCCCBBBB002 | ABCDEFGH-0001 | 550 |
+-----------+------------------+-----------------------+------------+
| 0001 | CCCCBBBB002 | ABCDEFGH-0001 | 600 |
+-----------+------------------+-----------------------+------------+
| 0001 | EEEEBBBB001 | ABCDEFGH-0001 | 200 |
+-----------+------------------+-----------------------+------------+
| 0001 | EEEEBBBB001 | ABCDEFGH-0001 | 201 |
+-----------+------------------+-----------------------+------------+
| 0001 | FFFFBBBB001 | ABCDEFGH-0001 | 999 |
+-----------+------------------+-----------------------+------------+
| 0001 | FFFFBBBB001 | ABCDEFGH-0001 | 800 |
+-----------+------------------+-----------------------+------------+
Result:
+-----------+------------------+-----------------------+------------+
| ID | SERIAL | TAG | UNIT |
+-----------+------------------+-----------------------+------------+
| 0001 | AAAABBBB001 | ABCDEFGH-0001 | 100 |
+-----------+------------------+-----------------------+------------+
| 0001 | CCCCBBBB002 | ABCDEFGH-0001 | 500 |
+-----------+------------------+-----------------------+------------+
| 0001 | EEEEBBBB001 | ABCDEFGH-0001 | 200 |
+-----------+------------------+-----------------------+------------+
| 0001 | FFFFBBBB001 | ABCDEFGH-0001 | 800 |
+-----------+------------------+-----------------------+------------+
Is it possible to achieve that?
