    <p>I was actually asked this myself a few weeks ago, whereas I know exactly how to do this with a SP or UDF but I was wondering if there was a quick and easy way of doing this without these methods. I'm assuming that there is and I just can't find it. </p> <p>A point I need to make is that although we know what characters are allowed (a-z, A-Z, 0-9) we <em>don't want to specify what is not allowed</em> (#@!$ etc...). Also, we want to pull the rows which <strong>have</strong> the illegal characters so that it can be listed to the user to fix (as we have no control over the input process we can't do anything at that point). </p> <p>I have looked through SO and Google previously, but was unable to find anything that did what I wanted. I have seen many examples which can tell you if it contains alphanumeric characters, or doesn't, but something that is able to pull out an apostrophe in a sentence I have not found in query form.</p> <p>Please note also that values can be <code>null</code> or <code>''</code> (empty) in this <code>varchar</code> column.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
