      Adding a limit to the query causes the table to be found.

      Description

      I’m using Teiid version 9.2.2. In some cases, using the makedep @<table> feature results in the makedep hint being ignored.
      I use this feature to apply a makedep to only one branch of a set operation, since makedep hints are not applied when placed on the individual queries in the set operation .
      My query looks like this:

      (Select bbb from ccc
      Intersect
      select abc.yyy from (select yyy from zzz) abc
      ) option makedep @abc.zzz

      In the debug plan in the “GENERATE CANONICAL” section, I see:

      MEDIUM [Hints] Unknown group specified in OPTION MAKEDEP/MAKENOTDEP: @abc.zzz - ignoring hint

      This only occurs if the query has no limit applied to it. If I add a limit option, it does find the table and apply the hint correctly.
