So it is being processed by Access before being sent to Postgres. My
experience with Access is that when it does that it creates queries that
are only understood by itself.
In the Query tab(working from memory) there should be an option to do a
Pass-Through query. This sends whatever you type to Postgres as written
and not reparsed by Access. In that paste:
SELECT
DISTINCT "public"."Orders"."Name"
FROM (
"public"."Orders"
LEFT OUTER JOIN "public"."POs" ON (
"public"."Orders"."OnlineCode" = "public"."POs"."OnlineCode" ) )
WHERE
"public"."Orders"."Name" IS NOT NULL
AND
char_length (trim ("public"."Orders"."Name" ) ) > 1
ORDER BY
"public"."Orders"."Name"
This will take Access out of the loop and help determine whether
psqlodbc is editorializing over what it is being passed in.
