Subject Conversion Error in Recursive Query
Author Ronan van Riet
Hello.

I could use some help with understanding why my query returns a partial record set and a conversion error from string "102".
SQL Message: -413
Engine code: 335544334


FlameRobin tells me myRecursive_VW has the following columns:
- ID Bigint
- PAR_ID Bigint
- NAME varchar(255)


I am using the following test to confirm the ID and PAR_ID are indeed integers.

SELECT a.ID+2, a.PAR_ID+2, a.NAME
FROM MYRECURSIVE_VW a

This test passed.


I also created a procedure and have the code run against that instead of my view.  Same result.


I do not see where the conversion is happening.  Any pointers?

WITH RECURSIVE  myCTEName (id,level,top_key,par_id,name)

as (
    select id
         , 0    as level
         , id   as top_key
         , null as immediate_parent_key, name
      from myRecursive_VW
     where par_id is null
        UNION ALL
    select chd.id,par.level+1,par.top_key,chd.par_id, name
      FROM myCTEName par
      JOIN myRecursive_VW chd
        ON chd.par_id = par.id
   )
select * from myCTEName


Best regards.
