I have two columns in a table and I want a query to fetch First column values based on distinct values from Second column. Since, There are multiple combinations of First and second column I would like to have the first match from each combination.
DATASET:
| First Column | Second Column |
|---|---|
| A | abc |
| B | abc |
| C | abc |
| D | abc |
| F | abc |
| G | abc |
| H | qwe |
| I | qwe |
| J | jkl |
| K | jkl |
| L | jkl |
| M | uio |
| N | uio |
Excepted Output:
| First Column | Second Column |
|---|---|
| A | abc |
| H | qwe |
| J | jkl |
| M | uio |
Just use MIN() and GROUP BY.
SELECT min(`First Column`) AS `First Column`, `Second Column`
FROM yourTable
GROUP BY `Second Column`
