A useful tool for building CAML queries in Microsoft SharePoint 2010.
This handy CAML Query Builder from U2U can be very useful in SharePoint development. I'll use it from time-to-time in future SharePoint and SPServices posts, but wanted to bring it to your attention
You'll notice the builder is built for SP 2003 and 2007 without mention of 2010. Here's a nice post explaining the bugs about using it with SP 2010. In general, though, I've had no issues using this application with SP 2010. My use is primarily to aid client-side development through the use of the SPService JavaScript library. The most important note in my use is to ensure you connect via SharePoint Web Services (see below).
