为每一轮创建映射和显示运行，我还将第一次运行添加到第二次运行的总和中，第三次运行相同

Question

Source table Cricket_Score :

Overs	Balls	Runs
1	1	1
1	2	2
1	3	4
1	4	0
1	5	1
1	6	2
2	1	3
2	2	1
2	3	1
2	4	4
2	5	6
2	6	0
3	1	2
3	2	1
3	3	1
3	4	6
3	5	0
3	6	4

I Want to an output like this:

Overs	Total_Runs
1	10
2	25
3	39

Description: - For First Over means First 6 Balls I Want Sum of First 6 Balls that is 10. & For Second 6 Balls I Want Sum of First 6 Balls [Over] + Second 6 Balls That is 25 [10 + 15 = 25]. & For Third 6 Balls I Want Sum of First 6 Balls [Over] + Second 6 Balls + Third ^ Balls That is 39 [10 + 15 + 14 = 39].

Note: - 6 balls means one over.

How to create a mapping in for this scenario in Informatica / which logic should I use?

Answer 1

i will assume your data is EXACTLY like you have shown in your question. If its not like this in source then it will be a major issue. If its a table where data is not sorted, it will be an issue.

Solution -

1. Create an expression transformation with below ports - in below order. in - input port, v_variable port, out_* output port

in_balls
in_runs  
in_overs
v_cumulative_runs= in_runs+ iif(isnull(v_cumulative_run),0,v_cumulative_run)
out_total_runs=v_cumulative_runs
out_overs=in_overs

2. Use an aggregator -

in_total_runs
in_out_overs -- group by this port
out_total_runs = max(in_total_runs)

3. Attach in_out_overs and out_total_runs links to target.
