无法从Hibernate本机查询的结果集中读取列值

Question

 SELECT
  CONCAT(CREG.FIRSTNAME, ' ', CREG.LASTNAME) AS NAME,
  CASE WHEN CR.CAMPAIGNTYPE = 'NPS'
    THEN NPSSCORE
  ELSE CSATSCORE END                         AS SCORE,
  IFNULL(cast(CC.TEXT AS CHAR(255)), '')     AS COMMENTS,
  CREG.ID                                    AS CLIENTID,
  CR.ID                                      AS CAMPAIGNRESPONSEID,
  CI.ID                                      AS ISSUEID
FROM CUSTOMER_ISSUES CI INNER JOIN (SELECT DISTINCT ISSUEID
                                    FROM ISSUE_DEPARTMENT_MAPPING
                                    WHERE CUSTOMERUSERID = 91 AND ISSUE_STATUS = 'New') IDM
    ON CAST(CI.FEEDBACK_DATE AS DATE) BETWEEN '2016-06-05' AND '2016-06-11' AND IDM.ISSUEID = CI.ID
  INNER JOIN CAMPAIGN_RESPONSE CR ON CR.ID = CI.CAMPAIGN_RESPONSE_ID
  INNER JOIN CLIENT_REGISTRATION CREG ON CREG.ID = CR.RESPONSECUSTOMERID
  LEFT OUTER JOIN CAMPAIGN_COMMENTS CC ON CC.CAMPAIGN_RESPONSE_ID = CR.ID;

The above query is running in the mysql-console properly ,but when I am integrating with the Hibernate,following error is thrown by Hibernate.

[BigIntegerType] could not read column value from result set: ID; Column 'ID' not found.

Try getting rid of the alias names in your SQL query.

Basically what happens here is when you run

SELECT
  CONCAT(CREG.FIRSTNAME, ' ', CREG.LASTNAME) AS NAME,
  CASE WHEN CR.CAMPAIGNTYPE = 'NPS'
    THEN NPSSCORE
  ELSE CSATSCORE END                         AS SCORE,
  IFNULL(cast(CC.TEXT AS CHAR(255)), '')     AS COMMENTS,
  CREG.ID                                    AS CLIENTID,
  CR.ID                                      AS CAMPAIGNRESPONSEID,
  CI.ID                                      AS ISSUEID

in JDBC it returns the column as CREG.ID instead of ClientID. So try running the query without the aliases, typically, there is a problem in JDBC with this. If you still insist on using aliases,add the following entry to JDBC URL in configuration file

[useOldAliasMetadataBehavior=true]
