Java ORA-01461用于继承的字符(1字节)列-需要使用SpringJDBC(扩展StoredProcess)使其工作

Java ORA-01461用于继承的字符(1字节)列-需要使用SpringJDBC(扩展StoredProcess)使其工作,java,jdbc,plsql,oracle11g,spring-jdbc,Java,Jdbc,Plsql,Oracle11g,Spring Jdbc,我有一个像这样的SP create or replace PROCEDURE myproc myvar in out mytable.mycol%TYPE Exception in thread "main" org.springframework.jdbc.UncategorizedSQLException: CallableStatementCallback; uncategorized SQLException for SQL [{call TESTLEOSP(?)}]; SQL s

我有一个像这样的SP

create or replace PROCEDURE myproc
  myvar in out mytable.mycol%TYPE

其中mycl是char(1字节)

从java代码中,我尝试将一个字符串/字符绑定到此变量,并得到

ORA-01461-只能为插入到长列中绑定长值

如果我替换为

 myvar in out varchar2
那就行了

有没有关于如何正确绑定Java代码中的值的想法

我确实希望继续使用%type作为存储过程输入参数

这不是重复的,因为它引用了一个char(1)列

更新

正在为此添加更多信息

首先,我不想使用任何不推荐使用的代码

其次,我不希望出现任何取消分配的异常

第三,更改DB和SP不是选项(为什么它们应该这样做?)

另外,我认为这可能与我没有访问此存储库的权限有关

一些观察

  • 很遗憾,OracleJDBC驱动程序不能处理这个问题
  • 另外,我不知道他们为什么一直使用不推荐的oracle.sql.CLOB类
  • 我真的不想使用CLOB,相信我,我已经尝试了很多东西
  • 我认为这仍然是一个次优的解决方案,所以如果有人找到更好的解决方案并在这里发布,我会很高兴
  • 我将这个解决方案保留在这里有两个原因:第一,因为它表明这个问题不是重复的。第二,因为我相信好的堆栈溢出答案为此类问题提供了客观且随时可用的答案。很明显,这个问题与字符集翻译有关。然而,这里重要的是一个在IMO中工作的代码示例

  • 我不是Java专家。但谷歌搜索显示了以下几点。看看是否有帮助
