Split one column into multiple rows

Question

Can anyone tell me how to accomplish this? A column in my table, in some instances, contains comma separated values. If it does, I need to create new rows for these values

Answer 1

I know this is an older post but thought I'd add an update. Tally Table and cteTally table based splitters all have a major problem. They use concatenated delimiters and that kills their speed when the elements get wider and the strings get longer.

I've fixed that problem and wrote an article about it which may be found at he following URL. http://www.sqlservercentral.com/articles/Tally+Table/72993/

I'll also tell you that a fellow by the name of "Peter" made an improvement even to that code (in the discussion for the article). The article is still interesting and I'll be updating the attachments with Peter's enhancements in the next day or two. Between my major enhancement and the tweek Peter made, I don't believe you'll find a faster T-SQL-Only solution for splitting VARCHAR(8000). I've also solved the problem for this breed of splitters for VARCHAR(MAX) and am in the process of writing an article for that, as well.
