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
我有一个像这样的SPJava 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
create or replace PROCEDURE myproc
myvar in out mytable.mycol%TYPE

Caused by: java.sql.SQLException: Parameter Type Conflict
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

我请求的java语言环境信息是使用以下代码生成的

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
提前感谢以下是我如何解决这个问题的。不幸的是,我无法避免撞车
