截断 Oracle PL/SQL 块中的多个表失败

Question

运行以下脚本：

import cx_Oracle

conn = cx_Oracle.connect(user = db_user, password = db_pwd, dsn = 'TULSA').
cur = conn.cursor()

sql = ("""  
        BEGIN
            truncate table shop_ord_temp;
            truncate table shop_ord_item_temp;
            truncate table shop_cust_temp;
        END;
    """)

cur.execute(sql)
cur.close()
conn.close()

运行此匿名块时收到此错误：

cx_Oracle.DatabaseError: ORA-06550: line 3, column 22:
PLS-00103: Encountered the symbol "TABLE" when expecting one of the following:

   := . ( @ % ;

Answer 1

你可以使用：

sql = ("""  
        BEGIN
            execute immediate 'truncate table shop_ord_temp';
            execute immediate 'truncate table shop_ord_item_temp';
            execute immediate 'truncate table shop_cust_temp';
        END;
    """)

这是一个 PL/SQL 功能，与 Python 无关。
