Oracle一个诡异的错误——Can bind a LONG value only for insert into a LONG column

CrmProductTaskEndAction : SqlMapClient operation; uncategorized SQLException for SQL []; SQL state [72000]; error code [1461];   
--- The error occurred in com/alibaba/intl/bops/crm/syslog/dao/ibatis/sqlmap/CRM_SYSLOG_EMAIL.xml.  
--- The error occurred while applying a parameter map.  
--- Check the CRM_SYSLOG_EMAIL.insert-InlineParameterMap.  
--- Check the statement (update failed).  
Error: java.sql.SQLException: ORA-01461: can bind a LONG value only for insert into a LONG column

原因就是字段超长。LONG column是Oracle老的BLOB数据类型，已经deplicated了，Use BLOB instead of LONG。

Datatype Description Max Size:Oracle 8 Max Size:Oracle 9i/10g Max Size:Oracle 11g Max Size:PL/SQL PL/SQL Subtypes/Synonyms

VARCHAR2(size)	Variable length character string having maximum length size bytes. You must specify size	4000 bytes minimum is 1	4000 bytes minimum is 1	4000 bytes minimum is 1	32767 bytes minimum is 1	STRING VARCHAR
LONG	Character data of variable length (A bigger version the VARCHAR2 datatype)	2 Gigabytes	2 Gigabytes - but now deprecated (provided for backward compatibility only).	2 Gigabytes - but now deprecated (provided for backward compatibility only).	32760 bytes Note this is smalller than the maximum width of a LONG column

但是将同样的SQL放在pldev终端直接跑，确实报另外一个错误：

ORA-01401:insert value too large for column

具体参考：Oracle/PLSQL: ORA-01401 Error

为什么同样的SQL，会跑出不同的错误结果，仔细看异常堆栈，发现前面的ORA-01461错误是Oracle JDBC驱动（ojdbc14）抛出来的。
