关于 ssm 框架 mybatis 更新数据库出错问题，大佬们帮解答下

[cway]

语言环境 Java，数据库 oracle （我不清楚跟数据库类型有没有关系）
例如有个表：biao 中有字段 a，限制长度为 4，但是我在程序里传的 a 值超过 4 个长度，如下：
update biao set a='12345'
然后理所应当会报错，但是第二次使用我传小于长度 4 的值进去提示“内部错误”，请问是怎么回事。该如何避免第一次数据库报错，第二次以及以后直接报“内部错误”，是要在 try catch 中对报错进行什么特殊的处理么？？

兄弟 描述 问题清楚点 异常贴出来 你这样描述说了等于没说

where

java.sql.SQLException: ORA-12899: 列 "biao.a" 的值太大 (实际值: 5, 最大值: 4)

@brucewuio 之后传正确值也都报内部错误

[Jrue0011]

看异常信息，错误是发生在"update BIAO set A= ? where ID=?"设置两个占位符的参数值时发生的？
看看你设置的参数值，最好代码也贴出来
