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

You'll have to wrap an IF check around it or change your query to return 0 instead of Null. If the field ...

table_info('','','','%') cannot return any types
I was recently confirming table_info special cases and discovered the case for getting table_types cannot work. table_info('','','','%') should return a list of table types but it returns a list of empty strings instead: my @types = $h->tables('', '', '', '%'); print "all types:\n", join("xxx\n", @types), "\n"; # should output something like: # "dbo" # "INFORMATION_SCHEMA" # "sys" # and actually outputs: xxx xxx It seems to be down to the following ...

'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...
