Error description

  • USER MIGHT RETRIEVE WRONG DATA FROM REMOTE ORACLE TABLES IF THE
    COLUMNS CONTAIN DATE TYPE AND THE DATA MIGHT BECOMES CORRECT AFT
    
    Root cause:
    Oracle client (OCI) doesn't send "ALTER SESSION" command which
    is to set the DATE data format immediately after connection with
    the environment variable NLS_DATE_FORMAT set to 'YYYY-MM-DD
    HH24:MI:SS'.
    

Local fix

  • Explicitly send "ALTER SESSION" command to Oracle server
    immediately after connection is setup. So that the DATE data
    format is set to what federation server understands before
    remote data query of DATE type.
