我试图删除模式中没有行的所有表，但在执行此代码时我犯了一个错误

THis is the code:


 create or replace procedure tester
       IS
       v_count NUMBER;
       CURSOR emp_cur
      IS
      select table_name from user_tables;
      BEGIN
          FOR emp_rec_cur IN emp_cur LOOP
            EXECUTE IMMEDIATE 'select count(*) from '|| emp_rec_cur.table_name INTO   v_count ;
            IF v_count =0 THEN
           EXECUTE  IMMEDIATE 'DROP TABLE '|| emp_rec_cur.table_name;
               END IF;

ORACLE_加载程序正在引发此错误。我怀疑您的循环正在查找一个外部表，该表的定义有问题-KUP-01008正在抱怨关键字“delimetered”，但外部表语法包含关键字“DELIMITED”

如果不打算删除外部表，可能需要在查询中省略它们，例如：

CURSOR emp_cur IS
SELECT table_name FROM user_tables
MINUS
SELECT table_name FROM user_external_tables;
