Gene,
Have you tried bracketing the statement off:
where;
(cwkt.clcode=ctwc.clcode) ;
and (cwkt.wccode=ctwc.wccode) ;
and( cwkt.trndate between ctwc.validfr and ctwc.validto);

Subject: SQL Error
Hello:
The following statement throws "SQL: Error correlating fields.":
select *;
from cwkt;
where;
funccode="TW" and trndate>={^2017.07.01} and;
exists;
(;
select .t. from ctwc;
where;
cwkt.clcode=ctwc.clcode and cwkt.wccode=ctwc.wccode and;
cwkt.trndate between ctwc.validfr and ctwc.validto;
);
order by clcode,wonbr,trndate
This statement works:
select *;
from cwkt;
where;
funccode="TW" and trndate>={^2017.07.01} and;
exists;
(;
select .t. from ctwc;
where;
cwkt.clcode=ctwc.clcode and cwkt.wccode=ctwc.wccode and;
cwkt.trndate>=ctwc.validfr and cwkt.trndate<=ctwc.validto;
);
order by clcode,wonbr,trndate
The only difference is the second line of the nested select's where
expression. The first uses between, and the second uses >= and <=.
What am I missing?
Sincerely,
Gene Wirchenko
