ORA-01741: illegal zero-length identifier

if(variable = “”) then
dbms_output.put_line(“varaiable is empty”)
end if;

While running the above code in pl/sql i got the error as “ORA-01741: illegal zero-length identifier”
and the fix is
if(variable is NULL) then
dbms_output.put_line(“varaiable is empty”)
end if;

Today learnt that In PL/SQL Cannot use empty double quotes (“”) for condition checking.
