Hi,
I used SQL Server 2000 Personal Edition. I created a stored procedure
having input parameters as smallint,tinyint,char,varchar and
smalldatetime. When I executed it by Query Analyzer, it's ok. But when
I executed it by ASP code that used ADODB.command, it showed error:
Invalid character value for cast specification .
Though SQL Server debugger, it showed:
Invalid character value for cast

Hi,
I have built a web application that will be a very high profile application.
We had tested it, demonstrated it and shown that it all works.
On a dress rehearsal run through, it failed spectacularly. I was so
embarrassed and felt like killing the person that made it fail. However,
when it goes live, IT MUST NOT FAIL.
The system has a backoffice system that takes an excel spreadsheet from the

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
