HANA SQL function to split a comma delimited string into substrings -


i have following hana procedure:

create procedure sp_lit()  begin declare count int; declare pos int; declare value nvarchar(100);  value := 'r,a';   if length(:value) > 0      value := :value + ',';     pos   := locate(:value,',',1); end if;     while :pos > 0     begin         insert [o/p table] values (left(:value,:pos-1));         value := right(:value, length (:value)-:pos);         pos := locate(:value,',',1);      end;     end while; end;

everything seems fine on execution following error thrown:

error: invalid number exception: invalid number: not valid number string 'r,a'

any idea going wrong?

i found solution. '+' sign in concatenation should replaced '||' pipe operator.
