Hi. 

I have two identical tables and I want to add the last column of the second table to the first table. But I want to change the variable names.

How do I program it?

 

Table 1

Group Setting Value
1 a 25
2 b 30
3 c 45

 

Table 2

Group Setting Value
1 a 48
2 b 59
3 c 35

 

Final output

Group Setting Value 1 Value 2
1 a 25 48
2 b 30 59
3 c 45 35

 

Thanks.

Thank you. If I use PROC SQL, how will the program look like?
