Is this a bug in SQL Anywhere 17.0.9 create or replace database variable testvar bit default 0;
create or replace function testvar()
returns bit
begin
if testvar = 1 then
return(1);
else
return(0);
end if;
end;
set testvar = 1;
select testvar;
select testvar();--why this delivers 0?

Odd, seems to be a bug with 17.0.11.6800, too.
The behaviour is as expected when the database variable is qualified within the function:
create or replace database variable dba.testvar bit default 0; create or replace function dba.testvar() returns bit begin if dba.testvar = 1 then return(1); else return(0); end if; end; set testvar = 1; select testvar; select testvar(); return 1 as expectedIt seems to affect a connection-level variable in version 16 as well.
create or replace variable testvar bit default 0; create or replace function testvar() returns bit begin if testvar = 1 then return(1); else return(0); end if; end; set testvar = 1; select @@version, testvar, testvar();@@version,testvar,testvar() '16.0.0.2512',true,false
@@version,testvar,testvar() '17.0.9.4882',true,false
