Hi, I have two input datasets and I want to create an output dataset like mentioned below. Thanks so much for your help and time.
1st input dataset:
key1 | key2 |
101 | 901 |
101 | 902 |
101 | 903 |
101 | 904 |
101 | 905 |
102 | 801 |
102 | 802 |
102 | 803 |
102 | 804 |
2nd Input Dataset:
key1 | key3 | key4 | var1 | var2 | var3 | var4 | var5 | varn |
101 | a1 | b1 | . | . | . | . | . | . |
101 | a2 | b2 | . | . | . | . | . | . |
101 | a3 | b3 | . | . | . | . | . | . |
102 | a4 | b4 | . | . | . | . | . | . |
102 | a5 | b5 | . | . | . | . | . | . |
102 | a6 | b6 | . | . | . | . | . | . |
Output dataset:
key2 | key1 | key3 | key4 | var1 | var2 | var3 | var4 | var5 | varn |
901 | 101 | a1 | b1 | . | . | . | . | . | . |
901 | 101 | a2 | b2 | . | . | . | . | . | . |
901 | 101 | a3 | b3 | . | . | . | . | . | . |
902 | 101 | a1 | b1 | . | . | . | . | . | . |
902 | 101 | a2 | b2 | . | . | . | . | . | . |
902 | 101 | a3 | b3 | . | . | . | . | . | . |
903 | 101 | a1 | b1 | . | . | . | . | . | . |
903 | 101 | a2 | b2 | . | . | . | . | . | . |
903 | 101 | a3 | b3 | . | . | . | . | . | . |
801 | 102 | a4 | b4 | . | . | . | . | . | . |
801 | 102 | a5 | b5 | . | . | . | . | . | . |

802 | 102 | a6 | b6 | . | . | . | . | . | . |
803 | 102 | a4 | b4 | . | . | . | . | . | . |
803 | 102 | a5 | b5 | . | . | . | . | . | . |
803 | 102 | a6 | b6 | . | . | . | . | . | . |
804 | 102 | a4 | b4 | . | . | . | . | . | . |
804 | 102 | a5 | b5 | . | . | . | . | . | . |
804 | 102 | a6 | b6 | . | . | . | . | . | . |
Thanks Again!

You are trying to get a cartesian product which is possible by proc sql as below
data have1;
input key1 key2;
cards;
101 901
101 902
101 903
101 904
101 905
102 801
102 802
102 803
102 804
;
data have2;
input key1 key3$ key4$ var1 var2 var3 var4 var5 varn;
cards;
101 a1 b1 . . . . . .
101 a2 b2 . . . . . .
101 a3 b3 . . . . . .
102 a4 b4 . . . . . .
102 a5 b5 . . . . . .
102 a6 b6 . . . . . .
;
proc sql;
create table want as select a.*,b.key2 from have2 as a left join have1 as b on a.key1=b.key1 order by a.key1,b.key2;
quit;
Why is there no key2=905 in the output?
