Will adding a column to table break asp.net app?
<p>I've inherited an ASP.NET web app, and I am coming up to speed on being a DBA as well.</p>

<p>Before I break anything, if I add a new column to a table, is there any chance it will break an existing page that does CRUD operations? The new column would not, of course, be part of the  existing operations and grid controls, and if I allow it to contain a NULL (so inserts don't require value input), will I be OK?</p>

<p>I realize that deleting a column could certainly break things. But adding a nullable column would seem to be harmless enough. (I think).</p>

<p>But I want to check!</p>

<p>Thanks</p>
