一直使用的是Oracle,最近的工作是进行系统部署发布。将原使用oracle的数据库迁移到DB2数据库上,过程中遇到了一些问题,觉得有必要记述一下供大家分享。让后来者以解惑,让过来者而温故。由于以前未接触过DB2,有什么不正确的地方还请见谅,谢谢!这次工作也萌发了我要系统认真的学习一下DB2的欲望,O(∩_∩)O哈哈~

以下是记述的DB2抛出的问题:

1.COM.ibm.db2.jdbc.DB2Exception:[IBM][CLI Driver][DB2/SUN64]SQL0401N  运算"="的操作数的数据类型不兼容。 SQLSTATE=42818

记述:在SQL文中有的条件直接用 字段 = #参数# 的形式,当传入的参数为null的时候,就显出了上面这个问题。在DB2中,当确定一个字段值是null且要作为条件的时候,请使用 “is” 而不是“=”。那么当某个字段必须要用“=”,而是否要作为条件则根据参数的值进行判断的话,则可以在程序中用if或者用ibatis的时候在SQL的配置文件中用进行判断。

而这种情况,也可能会报:程序类型超出范围。这样的错误!

2.com.ibatis.common.jdbc.exception.NestedSQLException:

记述:DB2中字符串右截断,即传入SQL文中的参数的长度大于数据表字段的设计长度。所谓的设计长度,即字段创建时定义的长度。出现上面这个错误,要么检查传入的参数是否正确,要么就是修改表字段的长度。

记述:这个问题是在SQL中使用的字段不明确。即SQL文中时候多表的时候,每个表都有别名,而在使用字段的时候没有明确的标注是哪个别名(表对象)中的字段。这个问题就要细心的检查了。O(∩_∩)O哈哈~

记述:这个问题即使用的字段在所在的SQL文中使用的数据表没有被定义。这时候要么增加相应的字段,,要么删除该字段在SQL文中的使用,当然要就系统逻辑的整体考虑。

5.警告:java.io.CharConversionException:EOF

记述:这个是说在打开某个页面的URL中存在“%”。最后在URL外加了一个处理的方法 encodeURIComponent()这个是在脚本中,在java中另行处理了,嘿嘿!

Explain the InnoDB Buffer Pool and its importance for performance.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.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
