Oracle ORA-00600: [dmlsrvColLenChk_2:dty] 错误原因及解决

群里有人贴了一个错误：
ORA-00600: 内部错误代码, 参数:[dmlsrvColLenChk_2:dty], [2], [0], [16896], [], [], [], [], [], [], [], []
ORA-06512: 在 "IDBG17_DEV.ETL_LINK13_LLR_BRN", line 44
ORA-06512: 在 line 2


MOS 上搜了一下，有篇文章说明：


ORA-00600: [dmlsrvColLenChk_2:dty], [2]During Insert [ID 437343.1]


An insert statement fails with thefollowing error and stack trace:
--insert 操作失败，并报如下错误。


ORA-00600: internal error code, arguments:[dmlsrvColLenChk_2:dty], [2], [], [],[], [], [], []


Stack trace:

一．导致这个错误的原因：


This is bug 5526494 whichis closed duplicate of base bug 6627733:


Bug 5526494.-P Base Bug 6627733
Abstract: ORA-600 [DMLSRVCOLLENCHK_2:DTY], [12] RUNNING INSERT AS SELECT


Base Bug 6627733
Abstract: OERI[dmlsrvColLenChk_2:dty] inserting NULLs into CHAR length semanticscolumn


This problem is introduced by the fix for Bug 3447792 .


--这个问题由bug3447792 引入。


ORA-600 [dmlsrvColLenChk_2:dty] can occur when inserting NULL values into  columns with character length semantics along with NULL into DATE or NUMERIC columns in an insert SQL.


--当把NULL 插入character 类型的字段时，或者 将NULL 插入DATE,NUMBERIC 类型的字段时会发生ORA-600 [dmlsrvColLenChk_2:dty] 错误。


eg: 
create table bug6627733
(
VAR_CHAR VARCHAR2(3 CHAR),
SOME_DATE DATE
);




INSERT ALL
WHEN 1=1
THEN
INTO bug6627733 ( VAR_CHAR, SOME_DATE )
VALUES ( NULL, NULL )
SELECT NULL FROM dual;
^
ORA-600




二．解决方法：


Bug 6627733 is fixed inOracle releases 10.2.0.5.0, 11.1.0.7.0 and 12.1.0.0.0.


--bug 6627733 在10.2.0.5 11.1.0.7.0 和 12.1.0.0.0以后已经修复。


To implement the solution, please downloadand apply Patch 6627733 if it is available for your platform.


--为了解决这个问题，也可以应用Patch 6627733.


In some cases, a possible workaround is to alter the columns of typeVARCHAR2(nn CHAR) as shown in the example below.


First identify table(s) involved in the failing query and then describe thetable(s). For example:




SQL> descr kf_abschluss_tst
Name Null? Type
-------------------------------- -------- ------------------
C_KONTO_ID NOT NULL VARCHAR2(19 CHAR)<==
C_MANDANT NOT NULL NUMBER(5)
B_ENDE NOT NULL NUMBER(18,3)
F_ZU_KOMPENSIERENDER_ABSCHLUSS NOT NULL NUMBER(1)
C_KONTO_ID_ZINSAUS VARCHAR2(19 CHAR) <==


WORKAROUND:
Modify columns of type VARCHAR2(nn CHAR) and remove maximum length sizecharacters


Example:
alter table kf_abschluss_tst modify (c_konto_id varchar2(19));
