Oracle 11g 11.2.0.1.0 使用exp无法导出空表的解决办法

[日期:2012-08-10] 来源:Linux社区  作者:scorpio3k [字体:]

Oracle 11g(11.2.0.1.0)中有bug,当表无数据时,,不分配segment

解决方法:

1、insert一行,再rollback就产生segment了。

该方法是在在空表中插入数据,再删除,则产生segment。导出时则可导出空表。

2、设置deferred_segment_creation 参数

SQL>show parameter deferred_segment_creation

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

deferred_segment_creation            boolean     TRUE

SQL> alter system set deferred_segment_creation=false;

改变后只对之后的表起作用,并且需要重启oracle服务才能生效

3、手动给空表分配空间

  • DECLARE  
  • /  
  • 11g(11.2.0.2.0)这个bug好像就修复了,建议用expdb 命令导出。

    Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
