I’ve got a set a of data that is basically this:
JobRow | Hours | Date | JobID | OriginalJobRow |
---|---|---|---|---|
101 | 4 | 2001-06-13 | 21777A | Null |
269 | 12 | 2004-11-30 | 24999A | 101 |
270 | 10 | 2006-06-02 | 26888A | Null |
I’d like to find a way to select all information from my table, replacing JobID values where OriginalJobRow isn’t null with the JobID from the JobRow column that’s equal to the OriginalJobRow’s value, just for the purposes of the SELECT query.
In this example, I’d like my SELECT to return 21777A as the JobID for JobRow 269, since OriginalJobRow isn’t null on that row.
How might I accomplish this in a SELECT query?
