Mar*_*ion 10 java database db2 websphere
有许多网页,人们将此消息显示为症状(后面的值SQLERRMC和驱动程序级别不同):
DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=M51Dev.CUSTOMER, DRIVER=3.61.65
包括一些在这里上StackOverflow的.
错误代码表示找不到对象 - 几乎总是表 - ,并且SQLERRMC参数的值包含相关对象的名称.在我可以发现的每一次出现中,解决方案只是他们需要使用模式名称限定表名.但是,正如您从上面的行中可以看到的那样,这不是这种情况.架构是M51Dev,表是CUSTOMER,并且它们都存在.
环境是WebSphere Application Server(在这种特殊情况下为7.0.0.31,但我有点怀疑它是相关的)在Windows Server 2003 R2上运行,在旧的XP机器上使用DB2 9.7.300.3885.数据源在WAS中定义,并通过JNDI检索.应用程序是用Java编写的,我们的SQL是通过Spring的JdbcTemplates 使用JDBC执行的.
WAS中的数据源定义包括一个名为的自定义属性currentSchema,该属性设置为M51Dev.
这是SQL的相关行(或其中之一,因为我们得到每个表的相同症状):
SELECT rundateOverride FROM customer WHERE customerId=1
这是堆栈跟踪的摘录.如果它有帮助我可以提供更多.
bad SQL grammar [SELECT rundateOverride FROM customer WHERE customerId=1]; nested exception is com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=M51Dev.CUSTOMER, DRIVER=3.61.65

就像一些背景:这是一个支持多个数据库平台的银行应用程序.我们使用各种版本的Oracle,MS SQL Server和DB2 for System i拥有多年的经验; 但我们使用DB2 LUW相对较新.尽管如此,我的一些同事仍然使用上述配置,至少在同一台机器上安装了WAS和DB2时.
我可以在具有WAS的机器上运行SQL客户端,并使用相同的参数连接到相关数据库并成功查询,包括使用SET SCHEMA M51Dev和不限定表名,我认为最接近模拟JDBC/JNDI环境.
