Connect SQL adds 'UNKNOWN_COLUMN_0' error in clipboard



When using Connect-SQL to retrieve data from external HP SQL/MX non stop database, an error message is added to the Clipboard page ResultsPage.pxResults(1):
.UNKNOWN_COLUMN_0: Column number 0 has an invalid name.

SQL is executed successfully and values are mapped to the clipboard irrespective of the above message in the clipboard.

Error Messages

Error in the Clipoboard page 'UNKNOWN_COLUMN_0: Column number 0 has an invalid name.'

Steps to Reproduce

Connect to SQLMX database with a select query and the result is not populated correctly

Root Cause

A third-party product issue. as per the jdbc type 4 driver specification, getColumnLabel() should return the column name but it is not. code changes are made at engine level to retrieve column name using 'getColumnName()' if 'getColumnLabel()' returns empty.
