EXP-00091: Exporting questionable statistics_MySQL教程
推荐:由于文件组 ‘DEFAULT’ 中的磁盘空间不足,无法为数据库 ‘TEMPDB’ 分配新页今天接到一个朋友的问题,sql server报由于文件组 DEFAULT 中的磁盘空间不足,无法为数据库 TEMPDB 分配新页,按照错误提示应该是tempdb空间不足,让其查看tempdb对应数据库文件大小为不到4g,查看其对应文件为自增长,硬盘空间还有40g多点,那应该没有问题。后来她说
一.出现EXP-00091错误
[oracle@localhost tmp]$ exp "'/ as sysdba'" tables=testxuchao.TAB_XN_PY_DICT \
> file=/tmp/xifenfei.dmp log=/tmp/xifenfei.log

当环境变量和数据库的不一致,在导出统计信息时候,会报EXP-00091错误。
二.查看NLS相关参数
[oracle@localhost tmp]$ echo $NLS_LANG
AMERICAN
SQL> col value for a30
SQL> select parameter,value from nls_database_parameters
2 where parameter like '%CHARACTERSET%';
PARAMETER VALUE
------------------------------ ------------------------------
NLS_CHARACTERSET ZHS16GBK
NLS_NCHAR_CHARACTERSET AL16UTF16
三.解决方法
1.设置NLS_LANG为NLS_CHARACTERSET
[oracle@localhost tmp]export NLS_LANG=american_america.ZHS16GBK
[oracle@localhost tmp]$ exp "'/ as sysdba'" tables=testxuchao.TAB_XN_PY_DICT \
> file=/tmp/xifenfei.dmp log=/tmp/xifenfei.log

2.使用statistics=none
[oracle@localhost tmp]$ exp "'/ as sysdba'" tables=testxuchao.TAB_XN_PY_DICT \
> file=/tmp/xifenfei.dmp log=/tmp/xifenfei.log statistics=none

分享:sqlserver多版本查看版本号今天要查询自己的装的sqlserver2008 是否是R2版本,搜索了下,发现很多人查询此问题,现在记录如下,通过版本命令查询 同时也了解了哥哥sql server的对应版本好,一看就非常清晰了,记录下 1、查看 SQL Server 2005/2008 版本号 select serverproperty('productversion'
