After doing some research, it looks like I am having problems either retrieving
CLOBs or just that the source database (Oracle 10gr2) is set to UTF-8 character
set.
I am trying to retrieve all columns and some (not all) rows from an Oracle
table which contain - among other things - 2 CLOB colum
Hi all,
I am trying to rectify a 'bug' that I've created, and hence wrote a test
for.
The code is within an error module, which is allowed to die() the
program upon failure. To compensate for this within the test, I use eval().
In this case however, I'm testing an 'add_trace()' method, that dies

$dbh->{LongReadLen} = 2;

correctly, this:
@rtn = $sth->fetchrow_array();
is giving me an array with two elements and this:
push @data, [ @rtn ];

It appears that IO::BufferedSelect does what I want! From its documentation:
