批量获取指定分区表的每个子分区行数!
不然手动查询太麻烦！
---查看指定分区表的每个子分区行数
create or replace procedure show_tabparcnt
(partiton_tablename in user_tab_partitions.table_name%type ) --输入参数
as
TYPE cur IS REF CURSOR RETURN user_tab_partitions%RowType; --声明游标类型为ref
a cur; --声明变量为ref游标类型
re number;
osname user_tab_partitions%rowtype;
begin
open a for select * from user_tab_partitions where table_name=upper(partiton_tablename);
loop
fetch a into osname;
exit when a%notfound;
execute immediate 'select count(*) from '||upper(partiton_tablename)||' partition ('||osname.partition_name||')'
into re;
dbms_output.put_line('用户分区表'||upper(partiton_tablename)||'的分区'||osname.partition_name||'的行数为:'||re||';');
end loop;
close a;
end;
