Creating a flag within PROC SQL

[guest1994]

Hi

I have this code below, and I'm trying to create a flag (MTH6=1) to indicate if an account exists within OUT_EXT.IAS_L2BS_&MTH6.

What would you suggest I do to my code, I've highlighted this with comments?

PROC SQL;
CREATE TABLE SPDSWORK.CARDS_ACCOUNT_DER AS
SELECT A.KEY_ACCT
,A.KEY_ORG 
,A.DATE_CLOSED
,A.DATE_OPENED

Show us a brief example. We don't know what you are trying to do.

Add

case
  when not missing(b.key_acct)
  then 1
  else 0
end as mth6

to your select.
