I am getting the data tree service error on the cms. I think it is because i have so many unpublished nodes.  I used a sql statment to delete the recycle bin.  IS there any kind of sql statement that I could use to delete all unpublished nodes? I cant even get my cms to load anymore. Below is my sql statement to empty the recycle bin. 

begin transaction

-- Uncomment below to verify the number of nodes returned is the 

-- same as the number of nodes that is in the Recycle Bin

-- select * from umbracoNode where path like '%-20%' and id!=-20

-- Delete all 'related' nodes and table contents...

use [cms.realeflow.com]

delete from cmsPreviewXml where nodeId in (select id from umbracoNode where path like '%-20%' and id!=-20)
