Conditional column with time range within power querry
Hi togehter;
I would like to achive the following: I have an table(table 1) with IDs and time ranges, e.g.:
| ID | From | To |
| ABC | 10.10.2023 | 15.10.2023 |
| DEF | 05.09.2023 | 12.12.2023 |
I have a nother table (table 2) which looks like this:
| ID | Date |
| ABC | 01.01.2023 |
| ABC | 02.01.2023 |
| .. | .. |
Here(within table 2) I would like to add an additinal column which writes an X in it when the time range of table 1 matches the date and ID column in table 2; like this:
| ID | Date | Match |
| ABC | 08.10.2023 | - |
| ABC | 09.10.2023 | |
| ABC | 10.10.2023 | X |
| ABC | 11.10.2023 | X |
| ABC | 12.10.2023 | X |
| ABC | 13.10.2023 | X |
| ABC | 14.10.2023 | X |
| ABC | 15.10.2023 | X |
| ABC | 16.10.2023 | - |
| ABC | 17.10.2023 | - |
| … | … |
Does anyone know how to achive that?
Thank you and cheers, Pete!

Wow, perfect! That works, thanks a lot!
I have just another problem occuring now; the table2 of mine is 10.000.000 rows long; now the querry takes forever; which was kind of fast before; because of this new implemented "x" feature; do you know any way how to make this more efficient?
Thank you!
Cheers, Pete
p.s. whats a good source to learn M as you used it above in a structured way?
