I want to merge table1 and table2 on Country_one and Time (for table1) and Country and Count (for table2).
When the table2 variables are missings, the merge have to be set on : country_two and Time (for table1)
and always Country and Count (for table2).
All the table1 's obs have to be in the final merged table [in= tb1 ... if tb1].
How to handle it as smartly as possible ?
Have a look at my attachment to see my different tables.
Thanks a lot !
Regards

You haven't answered my question, thus I have no idea what you really want to accomplish.
Your ask indicated that you wanted to know how to merge two files, always include all of the records from table 1 but, if no match was found for Country1, try to match on Country2.
That part is realtively easy. However, in your want table, you leave off one record, namely xw1 al bk 1t.
Also, your want table also suggests that you want to go beyond whether a match does or doesn't exist, but to use different times if a matching time has any missing values for var1-var15. Without specifying your rules, we can only guess what you are trying to do.
In the following, I've changed your time and data values so that I could see what my suggested code was doing. As such, I've recoded some of your times. Specifically, for time, I changed 5 to 2, 10 to 3, and 20 to 4. I also changed your Table2 var values to reflect the time value. Thus, for time 1, I used the values 1.1, 2.1 .. 15.1 and did the same for the entire table.
My suggestion is for you to review the following code, decide if it is doing what you want and, if not, let us know what rules you are trying to satisfy. Since no one has suggested a solution, I'd have to guess that no one on the forum yet understands exactly what you are trying to accomplish.

There's no way to predict what you are searching for as the final result. You will have to spell it out.
Final data wanted, in the attachement file.
Thank you !

Please consider embedding it directly into the post. Attachments are harder to work with, and there are often restrictions on downloading files.
In your final output where does the following line come from:
xb5 bk al 5t bk 5t 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
Art, CEO, AnalystFinder.com
You have a few instances of duplicated keys in table2. For instance you have two records with country=kz and count=5t. One of those records has valid values for all vars var1-var15, and the other doesn't. Which one should be used in the merging?
I can understand the desired result for the one record I asked about if you want to use the update statement after doing merges.
However, that wouldn't explain:
xf1 ca ca 10t ca 10t 1 2 3 4 5 6 7 8 9 10 . . . 14 15 obs replace by ===> 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
Please explain where the var1-var15 data comes from for that id.

Response to mkeintz:
It is true, in the table2, there are these two obs.
In the second, wisch have missing values, and only on missing var poitns, the merging is done on the condition:
Country_two = Country and Time = Count.
Country_two and Time ====> are from table1
Country and Count ====> are from table2
As i use here the same values for var1 to var15 (1 2 3 ... 15) , it will conduct to a duplicate obs in the final result. Don't consider that as an issue.
Thanks !
Again, the difficulty i face is to handle smartly, a merging on 2 different conditions.
The first for the non missing var values in table2 : Country_one = Country and Time = Count
The second for the missing var values in table2 : Country_two = Country and Time = Count
Country_one, Country_two and Time ====> coming from table1
Country and Count ====> coming from table2
Thanks a lot !

Tom (thank to him) has edited my post in order to answer to your ask.
Thanks a lot !

I don't see an answer to my question. Neither the match with country_one or country_two contain match with a record that contains data for var1 thru var15 inclusive, but you show values of 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
For that one record, please show where (from which Table2 record(s) those values are obtained.

First af all, i apologize for my long absence and i would like to think you (Mr Art297) for your precious help to us.
You are right, your question was not responded. Here I answer to it, but as it is so late where i live, i will look deeply to your
last post tomorrow. Thank you again.
First, it looks for the first merging condition and find a same
[bk 5t] in both table : Country_one and Counry are equal to (bk)
and Time and Count are equal to 5t.
Thus,it obtain the value of var6 to var15 as i noted [6 7 8 9 10 11 12 13 14 15] take from the table2.
As the values of var1 to var5 are missing in this obs, now it use
the second merging condition, that is Country_two = Counry and Time = Count.
For this condition, i find [al 5t] for table1 and the same and unique [al 5t] in table2. In this obs, i take the remaining values for var1 to var6.
Thanks and Regards
Now you still have to explain what do to if there are still missing values after the match is done using both Country values.
You also have to explain why one record from Table1 was totally left out of the example want table.
Art, CEO, AnalystFinder.com
It's still a little difficult to figure, but this must at least come close. Assuming you already have your TABLE1 and TABLE2 ...
data table1_key1 table1_key2;
set table1;
key = country1 || time;
output table1_key1;
key = country2 || time;
output table2_key;
run;
proc sort data=table1_key1;
by key;
run;
proc sort data=table1_key2;
by key;
run;
data table2_key;
set table2;
key = country || count;
run;
proc sort data=table2_key;
by key;
run;
That gives you enough data to find the matches based on either key:
data want1;
merge table1_key1 (in=keepme) table2_key;
by key;
if keepme;
run;
data want2;
merge table1_key2 (in=keepme) table2_key;
by key;
if keepme;
run;
Now the question is how to put them back together again. Here is a simple way that might need some tweaking.
proc sort data=want1;
by id country1 country2 time;
run;
proc sort data=want2;
by id country1 country2 time;
run;
data want;
update want2 want1;
by id country1 country2 time;
drop key;
run;
I think this does most of what you asked for. The piece I'm not sure about: which values of COUNTRY and COUNT belong in the final data set when some of the numbers may have come from different observations.
True, there is no corresponding obs for
[xw1 al bk 1t] (from table1) in my table2 example.
It is a non valontary omission When I was trying to get
something that resembled my data.
Its corresponding obs would have to be a [al 1t]
in table2. And it result to the absence of [xw1 al bk 1t]
in my final wanted table.
But nevertheless, I very much adhere to what you have proposed
[Art297 - Astounding], and this allows me to really obtain what I seek.
Thanking you
Regards
