As the error indicates, perl is just doing substitution and sticking in a hash
reference "DBI:db=HASH(0x221d94)->quote(Neil)” instead of what you want which
is the value of the method.
You have to assign the value of the quote() method to a variable to do
substitution that way:
my $qfn=$oraProdDBH->quote($first_name);
my $qmn=$oraProdDBH->quote($middle_name);
my $qln=$oraProdDBH->quote($last_name);
$oraProdDBH->do
(
"UPDATE CSI_HR SET FIRST_NAME=$qfn , MIDDLE_NAME
=$qmn , LAST_NAME=$qln , REC_MOD_DATE=SYSDATE WHERE ALT_EMP_NO = $alt_emp_no"
) or die "Failed to update csi_hr; $DBI::errstr\n";
Alternatively you can use parameter substitution:
my $cursor=$oraProdDBH->prepare("UPDATE CSI_HR SET FIRST_NAME=? , MIDDLE_NAME
=? , LAST_NAME=? , REC_MOD_DATE=SYSDATE WHERE ALT_EMP_NO = ?”);
$cursor->execute($first_name, $middle_name, $last_name, $alt_emp_no);
Which (IIRC) uses the $oraProdDBH->quote() method behind the scenes to escape
things.
Which accomplishes the same thing as the ->do statement above, but using
parameters instead, which makes the statement marginally faster to execute in
oracle, and a lot faster if you’re doing a lot of ‘em because the statement
plan gets calculated only once, then cached, like all queries with parameters.
