Elusive “String or binary data would be truncated” error

By , 08/19/2011 1:11 PM

This was driving me nuts. I have a very basic SQL code similar to

    -- some code
    EXEC Proc2 @val2 = @val1
    -- some other code

I was getting error “String or binary data would be truncated”, but only when 2 conditions were met:

  1. @val1 is quite large
  2. Either SQL Server/computer just restarted or stored procedure Proc2 was just updated (ALTER)

Error happened just by the fact of the EXEC Proc2 being there it didn’t even had to do anything, it could RETURN straight away. Both @val2 an @val1 are of a type NVARCHAR(max) so there is no reason for the error. The error happened only once, after that I can pass data of any size – and no error would happen. Like I said – nuts. Continue reading 'Elusive “String or binary data would be truncated” error'»

Use symlinks to serve subdomain content

By , 08/19/2011 12:21 PM

When you add a subdomain to your site, many hosting providers will automatically create a new physical folder on the server to match the subdomain name and to serve the subdomain content from. Which is all fine and good if your subdomain has a completely different content from main site/other subdomains.

But there’re situations when you need several subdomains to point to the same physical folder. Case in point: WordPress multisite install. There’s only a single installation of WordPress software, but depending on how you access it – it will serve different content. For example if you visit http://kitchen.galanter.net you will see a culinary blog, but if you open http://codecorner.galanter.net – a programming content will be served to you. This is achieved by WordPress by reading host header information (HTTP_HOST) and depending on header name (“kitchen” or “codecorner”) different content will be served. But it will be served from the same physical folder

Many hosting providers allow you to select root folder for the subdomains – in this case it’s easy: just add subdomain, point it to the root folder of the main domain and you’re done. But some, like my current host hard-code subdomain-subfolder relationship and it’s not allowed to change. In my case my root domain (which serves http://www.galanter.net) is physically located in /galanter.net/public folder. When I added subdomain codecorner, provider automatically created folder /galanter.net/codecorner/public which would have a completely different content, but I needed its content to be served from main /galanter.net/public folder, just pass “codecorner” HTTP host header to it. Enter symlinks. Continue reading 'Use symlinks to serve subdomain content'»
