Note to readers: Hendrix gives no expectation of a response to this fee...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...table_info('','','','%') cannot return any types
I was recently confirming table_info special cases and discovered the case for getting table_types cannot work.
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:
# and actually outputs:
It seems to be down to the following ...'b'..'a'
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'"
d:\>perl -e "print 'b'..'a'"
I expected empty list in latter case, like in
perl -e "print 'bb'..'a'"

: select * from TABLEA where COL1 IN('value1','value2''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
An IN list is treated ...'or' or 'union'
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
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 .

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.

How do I write a LINQ expression that does the following:
select * from SomeTable where SomeColumn in ('a', 'b','c')
There is no IN operator in LINQ (yet), but you can use Contains instead:
Jos...Select where column IN ('DC123', 'WQ242', 'GT654', 'EL982', ......);
Which will be faster given that the list of IDs can be quite
large (hundreds or thousands of IDs)?
For count = 1 to rows
ls_ID = dw_1.GetItemString(count, "id")
dw_2.Retrieve(ls_id)//RetrieveStart = 2
Or modifying the select statement...
select column1, column2.....where ID IN ('DC123', 'WQ242',
'GT654', 'EL982', ......);
you can also used an argument of the type string array with your datawindow
For count = 1 to rows
ls_id[count] = dw_1.GetItemString(count, "id")
