Hi there,
we've encoutered some strange behaviour with the chr()-Function and
NULL-Values today.
Let's assume this query :
->
select customerno from customer where customerno is not null
<-
"customerno" is Fixed 5,0
This query produces the results we've expected.
Whereas
->
select customerno from customer where chr(customerno) is not null
<-
produces no results. There should be the same results as above, in my
understanding.
Am I missing something in the documentation?
->
select name from customer where chr(name) is not null
<-
and
->
select name from customer where name is not null
<-
"name" is varchar(100). This one produces the expected results in both
variations.
Isn't it possible to compare a chr()ed numeric value to null?
/me is confused.
