I have two tables:

table: points

|key_id | name | x | y |
------------------------
|1      | A    |10 |20 |
|2      | A_1  |11 |21 |
|3      | B    |30 |40 |
|4      | B_1  |31 |42 |

table: pairs

|f_key_p1 | f_key_p2 |
----------------------
|1        | 2        |
|3        | 4        |

Table 'pairs' defines which rows in table 'points' should be paired. How can I query database to select paired rows? My desired query result would be like this:

|name_1|x_1|x_2|name_2|x_2|y_2|
-------------------------------
|A     |10 |20 |A_1   |11 |21 |
|B     |30 |40 |B_1   |31 |41 |
