While you asked for a SQL query I do this with a SWQL query in a Custom Query resource (NPM 10.6 or later to support ToLocal function)
SELECT
n.caption as Node
, '/Orion/NetPerfMon/NodeDetails.aspx?NetObject=N%3a' + ToString(n.nodeid) AS [_LinkFor_Node]
, '/Orion/images/StatusIcons/Small-' + n.StatusLED AS [_IconFor_Node]
, unmanaged
, tolocal(UnManageFrom) as Unmanage
, daydiff(getutcdate(), UnManagefrom)as [Days till Unmanage]
, tolocal(UnManageUntil) as Remanage
, daydiff(getutcdate(), UnManageuntil)as [Days until Remanage]
FROM Orion.Nodes n
where
(
unmanaged = 'true' and
(minutediff(getutcdate(), UnManagefrom) > -10080)
)
or
(
minutediff(getutcdate(), UnManagefrom) >0
and minutediff(getutcdate(), UnManagefrom) <10080
)
order by unmanagefrom
