Many thanks. Worked fine. Sadly, almost every one of the varchar columns I checked return near the max length. Is there still a huge performance penalty, if most of the rows come close to hitting the max of the defined varchar length? I suppose it depends on your data, and how you use it. Just curious to hear some opinions.
