Hey guys. I have a long piece of sql that I'm trying to take out of an
existing Access db and modify to work with Postgresql. I've started
trying to convert it, but I've come across a problem that I don't even
know how to describe, let alone google. Here's the function

INSERT INTO MemberMailingAddress (
mb_cn_num,
mb_acct_num,
isactive,
ismember,
ismail,
ispromomail,
... <trimmed for your convenience> ...

)
SELECT
mb_cn_num,
mb_acct_num,
mb_stat_cd<>1 as isactive,
mb_stat_cd=0 as ismember,
isactive and (mb_mail_cd=0 or mb_mail_cd=1) as ismail,
ismail and (mb_stat_cd=0 or mb_stat_cd=2) as ispromomail,
... <trimmed for your convenience> ...

FROM member
ORDER BY mb_cn_num, mb_acct_num
;

Specifically I'm looking at these two lines

isactive and (mb_mail_cd=0 or mb_mail_cd=1) as ismail,
ismail and (mb_stat_cd=0 or mb_stat_cd=2) as ispromomail,

which appear to use other fields it's preparing to insert as variables
in the determination of the values of other fields (I told you I
couldn't figure out how to explain it).

Does anybody have any idea what I'm talking about? I sure don't.
