I spent way too long yesterday trying to get a CAML query that would allow me to query on a lookup field and figured I’d share.
<rant>
First, one thing I find very annoying about SharePoint is that if you have an invalid query, the call to the GetItems() method returns all rows. What?? How ’bout a friendly exception that I have an invalid query??
</rant>
So here was the solution: the CAML query should be formatted with a type attribute of Lookup in the Value tag and the text of that element should be the same value that you’d see in the SharePoint UI.
For example:
<Where>
    <Eq>
        <FieldRef Name="GiftsForMom" />
        <Value Type="Lookup">Flowers</Value>
    </Eq>
</Where>

Looking at it now, this is reasonably straightforward. However, it didn’t click in my development-damaged brain, as the value you see in a lookup field when you inspect it in the debugger is something like 4;#Gift Types.

When constructing CAML queries you must use internal names by this wonderful exception:

Exception caught Microsoft.SharePoint.SPException: One or more field types are not installed properly. Go to the list settings page to delete these fields. —>
 System.Runtime.InteropServices.COMException (0x81020014): One or more field types are not installed properly. Go to the list settings page to delete these fields.

Few days back I was trying to install MOSS Add-In for SQL Server Reporting Services. The number of links below can show the problem that I have faced. Its very simple to install the add-in but configuration is not easy. Do read the installation and configuration guide before installing it on your server.

Microsoft SQL Server Reporting Services – Installation and Configuration Guide for SharePoint Integration Mode (Important)

From looking at the comment stream for the "Microsoft SQL Server 2005 SP2 Reporting Services integration with WSS 3.0 and MOSS 2007" blog entry that was posted back in February, I can see that some people are still having difficulty installing and configuring SSRS in "SharePoint Integration Mode." Fortunately for you, Raju Sakthivel, an architect in the Microsoft Consulting Services group, has taken the time and effort to perfect and then document the whole process in the attached installation/configuration guide (3.5 MB in Word 2007 format). I hope that you will find it useful. Please leave a comment if you have any additional questions or issues.

SSRS and SharePoint make a powerful combination! If you have implemented an innovative or value add solution with the combo, please leave a comment with a description of what you’ve done.
