Subject: Cast NULL into Timestamp?
Date: Fri, 10 Dec 2004 14:24:56 -0500
Message-ID: <41B9F808.2040909@kencast.com> (raw)
I have a table
create table temp
(
tempdate timestamp,
tempname varchar(10)
);
And I tried to insert the following:
insert into table temp (tempname, tempdate)
select distinct 'tempname', null from some_other_relevant_table;
And I got an error that says "column "tempdate" is of type timestamp ... but
expression is of type text... will need to rewrite or cast the expression".
I really need the distinct. Is there anyway to cast this NULL into a
timestamp or any other workarounds?
Thanks
Wei
