Branch: develop
Detailed requirement
Currently, we are hardcoding the rated_ind as “1” in the informixoltp:long_comp_result table.
We need to update the implementation so we’re fetching the rated_ind from the informixoltop:round table based on the round_id.
Use that value when entering entries in the informixoltp:long_comp_result table.
If the rated_ind is 0, the old_rating, new_rating, old_vol, new_vol for the new entries should be null.
If the rated_ind is 1, you need to fetch the latest entry from the informixoltp:long_comp_result table where rated_ind = 1 and based on the coder_id, and if there is an entry (existing data), use the new_* values as old_* for the new entry. For example, assuming lastEntry is the last entry from the informixoltp:long_comp_result table, you should set the following:
-
old_rating = lastEntry.new_rating
-
old_vol = lastEntry.new_vol
If it’s null (existing data does not exist), use null.
You also need to update all related tests so there are no failing tests.
Should you have any questions, feel free to ask on the challenge forum!
