最近使用Oracle导入导出数据时,遇到了不少的麻烦!遂对oracle数据库进行了认真的学习,总结了几种导入导出的命令方法,以备以后查阅。

数据导出:

 1、 将数据库test完全导出,用户名system 密码manager 导出到d:/daochu.dmp中  

exp system/manager@test file=d:/daochu.dmp full=y 

2 、将数据库中system用户与sys用户的表导出  

exp system/manager@test file=d:/daochu.dmp owner=(system,sys)

 3 、将数据库中的表inner_notify、notify_staff_relat导出   

exp aichannel/aichannel@testdb2 file= d:/data/newsmgnt.dmp tables=(inner_notify,notify_staff_relat)  

4 、将数据库中的表table1中的字段filed1以"00"打头的数据导出  

exp system/manager@test file=d:/daochu.dmp tables=(table1) query=/" where filed1 like 00%/"   

上面是常用的导出,对于压缩,既用winzip把dmp文件可以很好的压缩。  也可以在上面命令后面 加上 compress=y 来实现。

数据导入:

1 、将d:/daochu.dmp 中的数据导入 test数据库中。  

imp system/manager@test  file=d:/daochu.dmp   imp aichannel/aichannel@hust full=y  file=file= d:/data/newsmgnt.dmp ignore=y   

上面可能有点问题,,因为有的表已经存在,然后它就报错,对该表就不进行导入。  在后面加上 ignore=y 就可以了。

  2 、将d:/daochu.dmp中的表table1 导入 

imp system/manager@test  file=d:/daochu.dmp  tables=(table1)  

 基本上上面的导入导出够用了。不少情况要先是将表彻底删除,然后导入。 

注意: 操作者要有足够的权限,权限不够它会提示。 数据库时可以连上的。可以用tnsping test 来获得数据库test能否连上。

以上记载,只是oracle数据导入导出的最基本方法,在实际应用中会有各种因素影响导入导出的结果,所以要灵活运用这些最基本的命令,但也要统筹整个oracle运行的环境来考虑问题。

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.

Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
