Re: datatype from SQL

The fetch method on a DBI statement handle object returns a reference to an array containing the value, not the value itself (it's an alias for fetchrow_arrayref). You need to do something like:

if ($in{'requestID'} == $newUID->[0])
[download]

to get the value in the row.

Update
I just realized your code snippet says fetchrow, not fetch. To my knowledge, there's no fetchrow method in DBI. If you're not using DBI, ignore this note (what are you using?); if you are, what method are you actually calling?

Do not rebuke them with harsh words ... but rather lead them gently - with URLs - so that they may learn wisdom.

well, i tried your suggestion, changing $newUID to $newUID->[0], but it gave me the following error: `Can't use string ("1") as an ARRAY ref while "strict refs" in use at n +ewsedit.pl line 61.` [download] so i think that $newUID must be the scalar ref, not an array ref, right?	[reply] [d/l]

Something doesn't add up. If you're calling `fetchrow_arrayref`, then your `print` example should show `ARRAY(0x123456)` or some such. That error message you're getting indicates the actual value (not a scalar ref or an array ref) is contained in `$newUID`, which is not consistent with the return value from that method. Stop, take a deep breath, make sure your code says what you think, and then go through brian's Guide to Solving Any Perl Problem.

What version of DBI are you using and which DBD driver? You're use of $in{param} leads me to believe you're also using cgi-lib (instead of CGI) and may have a very old installation. -derby Update: And is this an XY Problem ... are you just trying to ~~get~~ create the next UID ... if so, most DB's have an auto-incrementing field feature.

i thought that might be the problem, but then, why does `print $newUID` [download] give me the value "2"?? (or "1", or whatever)??	[reply] [d/l]

i think i may have had the whole fetchrow_arrayref, now it's fetch...i may have cut & pasted an intermediate incorrect version. and, yes, i am using DBI	[reply]
