    <p>This is not how the <code>IN</code> operator works, see <a href="http://msdn.microsoft.com/en-US/library/ms177682%28v=SQL.90%29.aspx" rel="nofollow">msdn</a>. You say that weeklyfreq is of type nvarchar, so this seems to contain a comma-separated list of the values you want to check against. Otherwise I couldn't see a reason why you'd limit the subquery to a single row. For the IN operator to work the column would have to be of type int as well.</p> <p>What could work in this case:</p> <pre><code>SELECT * FROM Alerts WHERE N'%' + cast(DATEPART(dw, GETDATE()) as nvarchar(2)) + N'%' LIKE (SELECT weeklyfreq FROM Alerts WHERE Id = 1) </code></pre> <p>This assumes that weeklyfreq contains a series of one-digit numbers. Also, this will only work as long as the subquery returns only a single row. The current day of week is converted to varchar and enclosed in '%' to make the <code>LIKE</code> operator work.</p> <p>But I would not recommend to use this; if you can, store your data in a different way that allows for easier analysis.</p> <p>Also, I can't quite see where exactly you're going with this. For this to make any sense, the Alerts table of the outer select should be either referenced in the WHERE clause or within the subquery (that would then be a <a href="http://msdn.microsoft.com/en-us/library/ms187638.aspx" rel="nofollow">correlated subquery</a>).</p> <p>The only thing I can see that'd make sense is to lose the subquery, then it'd be</p> <pre><code>SELECT * FROM Alerts WHERE weeklyfreq LIKE N'%' + cast(DATEPART(dw, GETDATE()) as nvarchar(2)) + N'%' </code></pre> <p>This you can additionally filter for an user's ID by adding to the WHERE clause.</p>

    1. COThe issue was a smaller part of the big picture. I've posted the entire SP above. Thanks again for all of your help. I truly appreciate it. Like to buy you both a drink. I'm clicking on your check-mark as the answer, but I do appreciate both of your inputs. Cheers! [I think I posted this in the wrong place]

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.
