PLSQL中扩展表空间提示权限不足，是被别人限制了？

扩展表空间需要有“DBA”的权限。

你当前的用户原来的“DBA”权限应该是被回收了。

解决办法：

使用有“DBA”权限的用户，进行扩展表空间的 *** 作。

在有“DBA”权限的用户下，执行授权 *** 作，是你当前用户拥有“DBA”权限。

参考语句：grant sysdba to apps

正常的root是向上面的这些一样，所有的root权限都是开启的，但是我之前出现1045问题的原因发现了最底下的Event以及Trigger权限并没有加上

如果想要加上在navicat上有没有权限，这个时候就应该到本地cmd终端中进行权限的添加、

具体的 *** 作：

1. 可以进入数据库，但无update权限：

*** 作过程：在WINDOWS的DOS窗口下，进入MYSQL安装目录的BIN目录，

运行mysqld-nt --skip-grant-tables，当前窗口将会停止。

另外打开一个命令行窗口，执行mysql 如果提示没有这个命令，先进入MYSQL的安装位置下BIN目录再运行mysql

>use mysql

>update user set Update_priv ='Y' where user = 'root'

如果root 没有所有数据的权限

更新的MYSQL.USER表的所有字段中为N的为Y就可以了。

update user set Select_priv ='Y' where user = 'root'

update user set Insert_priv ='Y' where user = 'root'

update user set Update_priv ='Y' where user = 'root'

update user set Delete_priv ='Y' where user = 'root'

update user set Create_priv ='Y' where user = 'root'

update user set Drop_priv ='Y' where user = 'root'

update user set Reload_priv ='Y' where user = 'root'

update user set Shutdown_priv ='Y' where user = 'root'

update user set Process_priv ='Y' where user = 'root'

update user set File_priv ='Y' where user = 'root'

update user set Grant_priv ='Y' where user = 'root'

update user set References_priv ='Y' where user = 'root'

update user set Index_priv ='Y' where user = 'root'

update user set Alter_priv ='Y' where user = 'root'

update user set Show_db_priv ='Y' where user = 'root'

update user set Super_priv ='Y' where user = 'root'

update user set Create_tmp_table_priv ='Y' where user = 'root'

update user set Lock_tables_priv ='Y' where user = 'root'

update user set Execute_priv ='Y' where user = 'root'

update user set Repl_slave_priv ='Y' where user = 'root'

update user set Repl_client_priv ='Y' where user = 'root'

update user set Create_view_priv ='Y' where user = 'root'

update user set Show_view_priv ='Y' where user = 'root'

update user set Create_routine_priv ='Y' where user = 'root'

update user set Alter_routine_priv ='Y' where user = 'root'

update user set Create_user_priv ='Y' where user = 'root'

update user set Event_priv ='Y' where user = 'root'

update user set Trigger_priv ='Y' where user = 'root'
