Notes sql can only do 1 insert

I’m connecting to the database Person in names.nsf with Notes SQL(ODBC,latest version).The following inserts one line:

INSERT INTO Person (FullNameInput, CompanyName,MailAddress) VALUES (‘Test person1’, ‘Testcompany1’, ‘test1@test.com’)

The problem is I can’t insert a second line.

Repeating the same line as above doesn’t work.

Why can I only do 1 insert ? The second one is just ignored !

The strange thing is that I can delete multiple rows at a time …
