I have a table with below syntax and insert statements.
Now, the below rules should be applied to get the output..
1) If status is same, then fetch max(seq) record
2) If status is different, then apply below priority to fetch the records
Start - Priority 1 (High)
In Progress - Priority 2
Cancelled - Priority 3
Complete - Priority 4 (Lowest)
Means, the output for each order should look like below.
Can somebody please suggest the ways how to do it.
Thanks.
