Hi Harvey,


Hi Robert,
Thanks for answering.
Your suggestion, however, do not work on my Opensuse Leap 42.3 /
LibreOffice 5.3.3.2 configuration. >
I use the Query design feature to enter

"Vorname" || IFNULL( ' & ' || "Partnervorname", ' ' ) || "Nachname"
 or

"Nachname" || IFNULL( ', ' || "Vorname", ' ')

Both above return 0 (yes, zero!) for every record.
Only the "Partnervorname" field has NULL values. I didn't expect
concatenation to be treated like 'multiplication', but I learn
something new every day! Neverthless, something is not right here.

However, 
COALESCE ( CONCAT( "Vorname", SUBSTR( ' & ', 1 ), "Partnervorname",
SPACE( 1 ), "Nachname" ), CONCAT( "Vorname", SPACE( 1 ), "Nachname"
) )

delivers the required result.

Which database do you use? Internal HSQLDB? My system here: OpenSUSE
42.2, LO 5.4.1.2. Have tested all this code for the Base-Handbook, so
I
am interested why it shouldn't work for you. Must say I didn#t test
how
it would work when entering the code in GUI mode, not switching to
SQL mode.

Regards

Robert
