Oracle IMP-00010、IMP-00031的解决
1、首先说一下IMP-00010的问题
这里请看这篇文章Oracle 11g导出来的dmp导入到 10g的数据库(IMP-00010：不是有效的导出文件，头部验证失败)
（http://zhw2527.iteye.com/blog/1460651）下载了AlxcTools.rar就解决了
2、发生IMP-00031错误是因为我在服务器上sunbing/123456用户下采用的是exp sunbing/123456@orcl file=e：\2012\bk.dmp full=y 及将数据库orcl完全导出但是在orcl中有多个用户在本地的oracle中没有这些用户所以即使使用imp sunbing/sunbing file=e:\2012\bk.dmp full=y log=e:\2012\imp.log也会出错
解决方法：1、在导出数据库的时候不使用full=y的模式，只导出sunbing用户下的表exp sunbing/123456@orclfile=e：\2012\bk.dmp owner=sunbing
2、虽然使用的是full=y导出但是在导入的时候使用fromuser和 touser 指定imp sunbing/sunbing file=e:2012/bk.dmp fromuser=sunbing touser=sunbing log=e:2012/imp.log
fromuser就是把当前的dmp文件中的某一个用户下的数据取出。
touser就是把现在dmp文件中的数据导入到目标库的指定user下。
具体命令这样。
exp userid=system/manager owner=username1 file=expfile.dmp
imp userid=system/manager fromuser=username1 touser=username2 ignore=y file=expfile.dmp；

MySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AMThe string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.
MySQL: What length should I use for VARCHARs?May 09, 2025 am 12:06 AMThe best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
