 Description   

I run this script:

create or replace sequence t1;
 
create or replace sequence T1;
 
select nextval(t1), lastval(t1);
 
select nextval(T1), lastval(T1);
 
select lastval(t1), lastval(T1);

The last statement returnt these results:

+-------------+-------------+
 
| lastval(t1) | lastval(T1) |
 
+-------------+-------------+
 
|        NULL |        NULL |
 
+-------------+-------------+

Look wrong. The expected result should be:

+-------------+-------------+
 
| lastval(t1) | lastval(T1) |
 
+-------------+-------------+
 
|           1 |           1 |
 
+-------------+-------------+
