[FRG-48] cannot set a numeric value in a case statement for a column of real datatype #822

Closed dynamobi-build closed 12 years ago

dynamobi-build commented 12 years ago

[reporter="schoi", created="Thu, 16 Feb 2006 19:00:45 -0500 (GMT-05:00)"] Like FRG-47 but with columns of "real" datatype, and this time, cannot insert any numeric values.

Repro:
----------

create schema s;
set schema 's';

create table rT (c1 real primary key, c2 real);
insert into rT values(0, null);

-- these work
select c2, (case when c2 is null then c2 else c2 end) from rT;
select c2, (case when c2 is null then null else c2 end) from rT;

-- these fail (notice different errors)
select c2, (case when c2 is null then 0 else c2 end) from rT;

[author="angel", created="Thu, 16 Feb 2006 22:06:37 -0500 (GMT-05:00)"] I have some changes to CASE that should fix this issue. I'm planning to test and checkin my changes to the dt branch sometime this weekend.
