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

'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...

'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.

'or' or 'union'Hello
I was just wondering, in general what is better to use, an 'or' clause in a
select or a 'union' to join two selects together. Do both statements create
work tables?
Many thanks
Alex
I think OR will be better than union. because suppose u have 3 tables and using
OR u can join table a and table b and table c so each table will have only one
read. but using union
you will join table a and table b and in another query of union u will use
table (a or b) and table c
so ur one read is more in union .

'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'"

Comments:
I have just started using Thunderbird and while I find it quite
excellent- I suggest having a button to add addressees to 'BCC' as well.
Currently each 'BCC' addressee has to be selected manually.
I send e-mail to quite a number of people at a time and I do not wish to
readily spread others addresses easily.

'Value' should be between 'minimum' and 'maximum'.
I'm attempting to invoke with parameters:
Dim thing2 As New mydelsubPBStep(AddressOf pbStep)
Me.Invoke(thing2, "setMax", dt.Rows.Count) <---- this is where the error occurs
the delegate looks like this:
Private Delegate Sub mydelsubPBStep(ByVal mode As String, ByVal value As Integer)
the function it's calling looks like this:Private Sub pbStep(ByVal mode As String, ByVal value As Integer) Select Case mode.ToLower

'returns' vs 'of'I don't like the assignments of 'returns' and 'of'. I think it is easily confused. I've written
foo (Int $x)
returns Int
in examples and nobody noticed. As formal documentation, that scans right as the outer perceived return value type. But no, it's supposed to be
foo (Int $x)
of Int
instead. The returns keyword affects the implementation of the function, not the external contract.
Yet, if returns is missing it uses the of value by default, but if the of is missing it does not give static type checking to the caller, rather than using the sam...
What should ''.split('') return?Hi,
what should ''.split('') return? The empty list, or a list with one null
string?

Empty list would make more sense as a degenerate case. In
'a'.split('')
we don't return the null strings before or after 'a', just ('a').
