[jira] [Commented] (NIFI-2918) JDBC getColumnName may return empty string

["Toivo Adams (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-2918?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15588458#comment-15588458 ]

-----------------------------------

Hi,

I don't want to argue with SAP.
But maybe we should preserve current behavior?
I mean we still use getColumnName()
and when return value is null or empty String we try getColumnLabel()

I am not sure how other vendors use getColumnLabel()

Thanks
Toivo

> The SAP Hana JDBC Driver returns an empty string for getColumnName if the column name in the SELECT statement was aliased.
> Instead you have to call getColumnLabel on the ResultSetMetaData.
> SAP as a company feels this is per the JDBC spec, so they are not going to change it.
