Describe the bug
Trying to run updates dependant on an attribute existing however getting a Object reference not set to an instance of an object when running the query.

To Reproduce

if exists(select
    *
from metadata.attribute
where
    entitylogicalname='new_thetable' and
    logicalname='new_thecolumn') begin
   print 'Run Update'
end

Expected behaviour
If the subquery in the exists returns a record, the print statement should run (it errors), if the subquery doesn't return a record, no additional output is included (this does happen so the error only happens if the exists actually exists).

Environment (please complete the following information):

• SQL 4 CDS 10.1.0 within XrmToolkbox and direct through MarkMpn.Sql4Cds.Engine.
• Results of SELECT @@VERSION:
  Microsoft Dataverse - 9.2.25101.151
