Cast from type ''''DBNull'''' to type ''''String'''' is not valid.
How do I avoid getting this error:
Cast from type ''''DBNull'''' to type ''''String'''' is not valid.
I am trying to get values from the database into a form for updating using a Datareader, SQL is set to allow nulls for certain fields as they are not required but the only way I can get the form to display is by adding a space in SQL.
Is there another way around this?
Check if it is equal to DBNull.Value first and if it is, don't do the cast.Stanley Tan

Where in the code does it need to go?
I am using the following and it's the profile that isn't always requi...

'do' won't 'do' if '/'Greetings to All from Au,
Have a NetWare Perl 5.8.4 and wanted to tweak File\Spec\NW.pm to try and
standardise on '/' separators.
If I run a test script (t/uni/lower.t) with an unmodified NW.pm, it
calls t/uni/case.pl, that, in case.pl, (when the path separators are
'\'), the $file is '..\lib\unicore\To\Lower.pl' and the following code
portion works, with $simple getting a returned table:
sub casetest {
my ($base, $spec, $func) = @_;
my $file = File::Spec->catfile(File::Spec->catdir(File::Spec->updir,
"lib", &qu...

'b'..'a'Hello.
I'm using defferent 5.6.0's for Win32.
I wonder wheter following behaviour is intentional or not:
d:\>perl -e "print 'b'..'c'"
bc
d:\>perl -e "print 'b'..'a'"
bcdefghijklmnopqrstuvwxyz
I expected empty list in latter case, like in
perl -e "print 'bb'..'a'"

Hi sali1982,
It's really strange that you suddenly get the problem. I think you first need to check whether you've enabled role in web.config. Also, you need to check whether ...
'IN' Clause or 'OR'Hello,
[1]: select * from TABLEA where COL1 IN('value1','value2''valu3'....)
[2]:select * from TABLEA where COL1 = 'value1' OR COL1= 'value2' OR
COL1='valu3'.
TABLEA is a huge table and it has non-clustered index on COL1. Among the
above 2 queries, which query will give me the better performance or fast
response and WHY?
What is the difference between 'IN' and 'OR' clauses as for as Sybase
Optimization is concerned. Which is the better one to be used on huge
tables.
Thanks.
