DB2 查询未知列名 ERRORCODE=-4460, SQLSTATE=null [英] DB2 query Unknown column name ERRORCODE=-4460, SQLSTATE=null

问题描述

一位同事向我们所有人提出了一个查询失败的问题，该查询由于我们无法预测的原因而失败.我可以确认 ENOTE.EN_FILTER_VALUE_L.FILTER_VALUE_DECODE 确实存在于数据库中.至少有三个人盯着它试图找出拼写错误.

A co-worker has baffled us all with a query that is failing for reasons we can't divine. I can confirm that ENOTE.EN_FILTER_VALUE_L.FILTER_VALUE_DECODE does exist in the database. At least three people have stared at it trying to find misspellings.

查询:

SELECT sub.ID, sub.USER_ID, sub.EN_TYPE_CODE, 
typ.EN_TYPE_DESC, typ.APPL_CD, filterval.FILTER_VALUE_DECODE AGENCY_TYPE, 
sub.EN_TYPE_CODE CONCAT ' | ' CONCAT typ.EN_TYPE_DESC ENOTE_STRING, 
org1.ORG_LVL1_CD, org1.ORG_LVL1_DC,
org2.ORG_LVL2_CD, org2.ORG_LVL2_DC,
org3.ORG_LVL3_CD, org3.ORG_LVL3_DC, 
org4.ORG_LVL4_CD, org4.ORG_LVL4_DC 
FROM ENOTE.EN_SUBSCRIPTION_T sub 
LEFT JOIN ENOTE.EN_TYPE_L typ ON sub.EN_TYPE_CODE = typ.EN_TYPE_CODE 
LEFT JOIN ENOTE.EN_FILTER_OFFICE_T filteroffice ON sub.ID = filteroffice.SUBSCRIPTION_ID
LEFT JOIN UMC.ORG_LVL4_L org4 ON org4.ORG_LVL4_CD = filteroffice.ORG_LVL4_CODE
      AND org4.ORG_LVL3_CD = filteroffice.ORG_LVL3_CODE
      AND org4.ORG_LVL2_CD = filteroffice.ORG_LVL2_CODE 
      AND org4.ORG_LVL1_CD = filteroffice.ORG_LVL1_CODE 
      AND org4.STRUCTURE_CD = filteroffice.STRUCTURE_CODE 
LEFT JOIN UMC.ORG_LVL3_L org3 ON org3.ORG_LVL3_CD = filteroffice.ORG_LVL3_CODE 
      AND org3.ORG_LVL2_CD = filteroffice.ORG_LVL2_CODE 
      AND org3.ORG_LVL1_CD = filteroffice.ORG_LVL1_CODE 
      AND org3.STRUCTURE_CD = filteroffice.STRUCTURE_CODE 
LEFT JOIN UMC.ORG_LVL2_L org2 ON org2.ORG_LVL2_CD = filteroffice.ORG_LVL2_CODE 
      AND org2.ORG_LVL1_CD = filteroffice.ORG_LVL1_CODE
      AND org2.STRUCTURE_CD = filteroffice.STRUCTURE_CODE 
LEFT JOIN UMC.ORG_LVL1_L org1 ON org1.ORG_LVL1_CD = filteroffice.ORG_LVL1_CODE 
      AND org1.STRUCTURE_CD = filteroffice.STRUCTURE_CODE
LEFT JOIN ENOTE.EN_FILTER_VALUE_L filterval ON 
   (filteroffice.AGENCY_TYPE_CODE = filterval.FILTER_VALUE AND filterval.FILTER_NAME   = 'Agency Type')

例外:

com.ibm.db2.jcc.a.SqlException: [jcc][10150][10300][4.3.111] 无效参数:未知列名 FILTER_VALUE_DECODE.错误代码=-4460，SQLSTATE=null

com.ibm.db2.jcc.a.SqlException: [jcc][10150][10300][4.3.111] Invalid parameter: Unknown column name FILTER_VALUE_DECODE. ERRORCODE=-4460, SQLSTATE=null

推荐答案

我在这里重新问了这个问题 db2jcc4.jar Invalid parameter: Unknown column name 得到了答案.

I re-asked this question here db2jcc4.jar Invalid parameter: Unknown column name and got the answer.

Hibernate 3.x 和 DB2 9.5 及更高版本中的 JCC 驱动程序的组合存在规范级别不匹配.升级到 Hibernate 4.x 将解决问题，但如果您不能在短期内这样做，设置 useJDBC4ColumnNameAndLabelSemantics=2 的自定义数据源属性可以解决问题.

The combination of Hibernate 3.x and the JCC driver in DB2 9.5 and above have a spec level mismatch. Upgrading to Hibernate 4.x will solve the issue, but if you can't do that in the short term setting a custom data source property of useJDBC4ColumnNameAndLabelSemantics=2 solves the issue.
