Question

Im trying to do a left join on two tables to get all values that do not exist in table 2 or have a status of null:

Table 1 has ROID as long

Table 2 has ID long, Type long, and Status text.

This works fine on Vista and Win 7 (I get all the records that do not exist in V), but I get no records on XP,

  SELECT roid
  FROM
  wo AS w LEFT JOIN VFlag As V ON (w.roid = V.ID AND V.Type = 2)
  WHERE
  (V.Status is Null) 

When I remove the V.Type = 2, it works fine on XP/Vista/7, but I need to qualify on Type as well:

SELECT roid
  FROM
  wo AS w LEFT JOIN VFlag As V ON (w.roid = V.ID)
  WHERE
  (V.Status is Null)  

This is both in VB6 using ADO and VisData. Trying WHERE isnull(V.Status) did not make any difference. XP machines (two tested on) are SP3.

Answer 1

Have you tried placing the V.Type = 2 in the WHERE clause instead of the join?
