Oracle学习笔记--- ORA-00911: invalid character 解决办法

在跑一段程序的时候，测试执行sql语句，报错 ORA-00911: invalid character

源码：

print "generate the primary_key , seral_key sql ==========================>"
        primary_key_sql = "select CONSTRAINT_NAME from user_constraints where table_name = '%s' and constraint_type = 'P';"%(table)
        serial_key_sql = "select sequence_name from user_sequences;"
        maxval_sql = "select max_value from user_sequences"
        print "gain the serial_key ==============================>"
        serial_key = self.execute_meod(serial_key_sql)

上述sql语句执行时报错，解决方案如下：

将每个sql语句的最后 “ ; ” 去掉。
