I have looked at the script of column size change and see that SSMS will create temp tables and then rename them. In test, in my - fairly small database - the change worked without a problem. But my customers have bigger tables. So my question, what - in relative terms - would constitute a "big" table? For example, I estimate that among my customers the biggest table where such change has to be done is about 500,000 rows. Is this "big" that could cause a problem? And if so, anything I can do in their SQL Server database to deal with this?

>If you are concern, generate script from SSMS and analyze it. Quite often SSMS will do modifications through creating a temp table instead of using ALTER TABLE. Could be a problem for big tables.
