Good Question. I've been stung by this in production early on in my career. Since then I always have specified the length of my varchar's.I've read the complaints about coallation. I always assume default out of the box coallation for QOD but you all have a point since many of you are outside the US and have different coallations. I think if we took in consideration every tiny thing that we normally assume the question may take pages and pages to set up.
Thanks - your comment made me wonder why SQL doesn't just throw an error when the varchar definition doesn't include a size. What is the purpose of having two default values based on the kind of declaration vs. CAST and CONVERT, given the possible bad side effects?
Just wondering.
