I have a sub-query as follows:
(SELECT D2.DSDECODED FROM DS_02 D2 WHERE D2.DSDECODED ="TREATMENT UNBLINDED" AND D.USUBJID=D2.USUBJID) AS DECODE
How do I program so, instead of DECODE taking the value of D2.DSDECODED(TREATMENT UNBLINDED), it now takes the value of either "YES", when D2.DSDECODED ="TREATMENT UNBLINDED", or
"NO", when D2.DSDECODED ="TREATMENT UNBLINDED" is false
Thank you in advance for your help!
Maybe you could use a CASE statement? Although I'm not sure why you have WHERE D2.DSDECODED ="TREATMENT UNBLINDED". Don't you want to include records that aren't DSDECODED="TREATMENT UNBLINDED". In that case you could do something like this:
(SELECT
(CASE
WHEN D2.DSDECODED="TREATMENT UNBLINDED" THEN "YES"
ELSE "NO"
END) AS DECODE
FROM DS_02 D2 WHERE D.USUBJID=D2.USUBJID)

Hi JediApprentice,
Thank you for the below suggestion! The logic worked the way you have it.
In terms of condition WHERE D2.DSDECODED ="TREATMENT UNBLINDED", if I have it, the code works to only set "YES" for the "DECODE" Flag, if removed, it evaluates to more than one row, breaking the code.
