Question

This is my H2 table.

| Step 1 | time |
| Step 2 | time |
| Step 3 | time |
| Step 4 | time |
| Step 5 | time |
| Step 1 | time |
| Step 2 | time |
| Step 3 | time |
| Step 4 | time |
| Step 5 | time |

I need to write a SQL query that fetches the result like so:

| Step 1 | time | time |
| Step 2 | time | time |
| Step 3 | time | time |
| Step 4 | time | time |
| Step 5 | time | time |

How do I fetch it this way? Is this possible?

Answer 1

If you have more than two values for each step, you could do

SELECT step_col, GROUP_CONCAT(time_col)
FROM H2 GROUP BY step_col

Then you can easily split time_col values in your code.
Check GROUP_CONCAT syntax to understand how you can use it the way you please.
