Selecting latest score

gopilth — Wed, 29 Jan 2014 21:12:36 GMT

Hi,

In the following scenario, I should output scores only if score1> score2 for corresponding games, for each player for each game but if a score is "." then I should use latest score for that player from games before '.' ;

for example if score2 of D3 is "." then compare Score1 of D3 with latest score2 before D3 (Latest score2 of D1orD2, cannot use score2 from D4 or above).

any suggestions?

Thanks in advance for your help.

Table1

Player	Game	Score1
1	D1	10
1	D2	20
1	D3	30
2	D1	40
2	D2	50
2	D3	10
2	D4	20
2	D5	30
3	D1	20
3	D2	10
3	D3	30

Table2 Player	Game	Score2
1	D1	10
1	D2	15
1	D3	.
2	D1	40
2	D2	5
2	D3	.
2	D4	15
2	D5	10
3	D1	5
3	D2	.
3	D3	15

Output Required---Where Score1>Score2

Player	Game	Score1	Score2
1	D2	20	15
1	D3	30	15
2	D2	50	5
2	D3	10	5
2	D4	20	15
3	D1	20	5
3	D2	10	5
3	D3	30	15

What?

Post a sample of what you want your output to look like please.

This looks like an update but I'm not sure. You mention time but I don't see any indication of time in the dataset.

Here is one way:

data want (drop=last);

set table1;

set table2;

retain last;

by player game;

if first.player then call missing(last);

if not missing(score2) then last=score2;

if missing(score2) then score2=last;

if score1 gt score2 then output;

run;
