Oracle数据库工作中常会遇到将TXT文件导入到Oracle中进行处理的问题，这样可以对TXT中数据进行分析处理。下面就将完整的导入及处理方法列出，当做参照吧。

大多来自其他部门的数据都是以.xls形式存在的，首先我们需要将其中的列数据进行处理，存入TXT中。

可以直接将这列数据复制到Notepad++之类的文本编辑器中，这样的目的是为了防止产生DOS下的换行符的存在，否则在导入Oracle数据库的时候不会成功。

复制进来的这列数据的最后一行总会是空行，需要将其删除。

生成一个TXT文件，我们生成的是1.txt。

现在将1.txt通过FTP上传到Linux你所使用的脚本目录下，以方便我们的导入。

在导入的时候我们需要使用两个程序，一个是导入脚本daoru.sh一个是导入控制文件daoru.ctl。上图为导入脚本文件的全部程序，我们导入的列只有一个，所以只需要建立一列TABLE PHONE_NO，就可满足我们的需求，若是列数更多，可以自行添加。

上图为控制文件daoru.ctl。我们需要做的是执行daoru.sh脚本，以生成临时表hh_tmp1，并插入一列PHONE_NO char(11)的字段，手机号码为11位，我们取char(11)即可。

执行之后，很快，我们的1.txt文件已经导入到了数据库的临时表hh_tmp1中，由于在daoru.sh脚本中，我们已经对导入的数据进行了剔除重复的操作，所以下面只要按照我们的需要来提取出来我们想要的数据即可。

我们使用的是PLSQL Developer，PLSQL Developer所登录的数据库用户必须与你在脚本中所使用的数据库用户一致，通过于原有数据库表进行连接，以实现获取我们所需要的数据。

提取出两列分别为PHONE_NO，BELONG_CODE，其中BELONG_CODE升序排列，以区分来自区域。

还有一句就是想把1.txt转换为excel格式，然后在windows打开。但是在linux环境下执行的语句。

cat exp_imp_report.list|sed 's/|/\t/g' >1.xls

Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
