Finding days between project status changes
I have tried a number of things to try to make this work but I can not seem to figure it out. I have a project table which holds the created date for a project and a status table which holds status change dates and project status as a decimal. A project may have many different status changes.
My Goal is to find the time between the created date for a project and each status change. I am not sure if I need to use the project table or not considering the status tables contains the created date for the project.
| Project ID | Status Extract | Status Change Date | Created date |
| 13568 | 3.0 | 7/15/20 | 7/10/20 |
| 13568 | 4.0 | 7/16/20 | 7/10/20 |
| 15598 | 1.0 | 7/18/20 | 7/16/20 |
| 15598 | 2.0 | 7/20/20 | 7/16/20 |
| 13568 | 3.0 | 7/20/20 | 7/10/20 |
Things to keep in mind: a project can go backwards or forward with status changes, status Extract starts at 1.0 and ends a 4.0, and there is a Primary key on the status table. Product ID is the FK in the status table while it is the primary key in the product table.
I have tried a couple things. This is an example of one thing I have tried but it didn't work.
ConnorH , What output you need. You have created date and status date with you, you can take a date diff.
new column = Datediff([created_date],[status change date],day)
In case you want to have diff with the previous record. refer to this
