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
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:
--- The error occurred while applying a parameter map.
--- Check the ManageLog.queryWarnModuleOlapFile-InlineParameterMap.
--- Check the statement (query failed).

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!
