create or replace procedure t_table_count_test as
v_tablename varchar2(50);
v_count integer;
str_sql varchar2(200);
–從all_tables裡面獲取的所有表的表名稱,儲存在游標內
cursor mycursor is
select t.table_name from all_tables t;
begin
if mycursor%isopen = false then
open mycursor;
end if;
–獲取游標的當前表名
fetch mycursor into v_tablename;
while mycursor%found
loop
–根據當前表名，獲取表內的資料量
str_sql := 'select count(*) from '||v_tablename ;
execute immediate str_sql into v_count ;
–列印表名和資料量。
dbms_output.put_line(v_tablename||』:』||v_count);
fetch mycursor into v_tablename;
end loop;
end t_table_count_test;
