Why is JPA throwing SQLCODE=-302, SQLSTATE=22001 for select query

Question

I'm trying to frame a select query using JPA repository.

select * 
from Foo 
where name = 'testapp'.

The "NAME" column is defined as varchar(4). My program throws SQLCODE=-302, SQLSTATE=22001 for the select operation whereas I get the same query working in the SQL developer IDE.

那很奇怪！您是如何获得数据的？testapp＆＃39;插入到表格的名称列中。如果将其定义为VARCHAR（4），则首先不能插入超过4个字节的内容。你确定它是VARCHAR（4）吗？
