ORACLE用LIMIT实现相仿分页

....................................................................

declare
type name_arrary_type is varray(20) of varchar2(10);
name_arrary  name_arrary_type;
rowss int:=&输入页记录数;
dpno int:=&输入部门号;
v_count int:=0;
cursor  emp_cursor(dpno int) is select ename from emp where deptno=dpno;
begin
open emp_cursor(dpno);
loop
fetch emp_cursor bulk collect into name_arrary limit rowss;
dbms_output.put_line('部门'||dpno||'员工:');
for i in 1..(emp_cursor%rowcount-v_count) loop
dbms_output.put_line(i||'    '||name_arrary(i)||'  ');
end loop;
dbms_output.put_line('当前页数:'||(v_count/rowss+1));
dbms_output.new_line;
v_count :=emp_cursor%rowcount;
exit when emp_cursor%notfound;
end loop;
dbms_output.put_line('每页['||rowss||']条记录,总页数:['||ceil(emp_cursor%rowcount/rowss)||']');
close emp_cursor;
end;

运行结果:

部门20员工:
1    SMITH 
2    JONES 
3    SCOTT 
4    ADAMS 
当前页数:1

部门20员工:
1    FORD  
2    YA_PING 
当前页数:2

每页[4]条记录,总页数:[2]
