Relation does not match record, if the field is empty


FileMaker Pro


11v3, 12v4

Operating system version

Windows XP/7 - it doesn't matter

Description of the issue

If you have empty field in table (A) and you want to match all records from same table, no records are matched.

A    <->  A copy
field [value is empty] =   field

Steps to reproduce the problem

Create table A with an indexed field and auto-increment id.
Create 3 records: two with the field empty and one with some value

In relationship diagram, make relation to table A (A copy) with match(=) on that field.

Look into dataviewer on record with empty field and you see that no records are listed - List(A copy::id).

Expected result

Filemaker should list all records where field is Empty (NULL).

Actual result

Filemaker selects no records.

Create second field with indexed calculation and change relation to Field_Calc: If (IsEmpty(Field); ""; Field)
