Hello,

I want to add/sum up and merge two columns that are in 2 different tables. What is the best logic/method that would be used for this type of situation?

 

For example, I want to join Table A & B and merge the 'Amount' column and sum up the numbers. 

 

Table A

Security GroupMETHODAmount
   
Unprotected%10
ProtectedFlat10
ProtectedFlat10
ProtectedFlat10
ProtectedFlat10
ProtectedFlat15
Unprotected%15
ProtectedFlat15
ProtectedFlat20
Protected%50
Protected%100

 

 

Table B

Active vs. ExpiredSecurity GroupMETHODAmount
    
ActiveUnprotected%10
ActiveProtectedFlat10
ExpiredProtectedFlat10
ExpiredProtectedFlat10
ExpiredProtectedFlat10
ActiveProtectedFlat15
ActiveUnprotected%15
ExpiredProtectedFlat15
ActiveProtectedFlat20
ExpiredProtected%50
ActiveProtected%100

 

The desired result for  Table C:

Active vs. ExpiredSecurity GroupMETHODAmount
    
ActiveUnprotected%20
ActiveProtectedFlat20
ExpiredProtectedFlat20
ExpiredProtectedFlat20
ExpiredProtectedFlat20
ActiveProtectedFlat30
ActiveUnprotected%30
ExpiredProtectedFlat30
ActiveProtectedFlat40
ExpiredProtected%100
ActiveProtected%200

If you are absolutely certain that the tables match, line per line, simply do this:

 

data c;
set a;
set b(rename=amount=extra);
amount = amount + extra;
drop extra;
run;

You can't do this using proc sql as it doesn't necessarily read tables sequentially. You need a data step here.
