Error description

  • db2look generates incorrect function mapping DDL causes users
    need to refine their db2look output before running it to
    recreate their federated objects.
    
    -- --------------------------------
    -- DDL Statements for FUNCTION MAPPING
    -- --------------------------------
    CREATE FUNCTION MAPPING "FM_TO_CHAR"
       FOR "SYSIBM".TO_CHAR(SYSIBM.TIMESTMP,SYSIBM.VARCHAR)
       SERVER "SERV1"
       OPTIONS
          (REMOTE_NAME  'TO_CHAR'
          );
    
    In above DDL, TIMESTMP  should be  TIMESTAMP,   VARCHAR should
    be
    VARCHAR().
    
    Reproduce:
    
    create wrapper net8;
    create server serv1 type oracle version '11.1' wrapper net8
    options(node '****');
    create user mapping for <USER NAME> server serv1
    options(remote_authid '<USER ID>',remote_password '<PASSWORD>');
    CREATE FUNCTION MAPPING FM_TO_CHAR  FOR
    SYSIBM.TO_CHAR(SYSIBM.TIMESTAMP,SYSIBM.VARCHAR()) SERVER serv1
    OPTIONS (REMOTE_NAME'TO_CHAR') ;
    
    
    db2look  -d <db name> -e -fedonly -o db2look.sql
    
    -- --------------------------------

          (REMOTE_NAME  'TO_CHAR'

    DB21034E  The command was processed as an SQL statement because
    it was not a
    valid Command Line Processor command.  During SQL processing it
    returned:
    SQL0104N  An unexpected token "VARCHAR" was found following
    "IBM.TIMESTMP,
    SYSIBM.".  Expected tokens may include:  "LONG".  LINE NUMBER=1.
    SQLSTATE=42601

    "SYSIBM".TO_CHAR(SYSIBM.TIMESTMP,SYSIBM.VARCHAR()) SERVER
    "SERV1" OPTIONS (REMOTE_NAME'TO_CHAR') "
    DB21034E  The command was processed as an SQL statement because
    it was not a
    valid Command Line Processor command.  During SQL processing it
    returned:
    SQL0204N  "SYSIBM.TIMESTMP" is an undefined name.  LINE
    NUMBER=2.
    SQLSTATE=42704
    
    => db2 "CREATE FUNCTION MAPPING "FM_TO_CHAR" FOR
    "SYSIBM".TO_CHAR(SYSIBM.TIMESTAMP,SYSIBM.VARCHAR()) SERVER
    "SERV1" OPTIONS (REMOTE_NAME'TO_CHAR') "
    DB20000I  The SQL command completed successfully.
    

Local fix

  • Replace TIMESTMP with TIMESTAMP, VARCHAR with VARCHAR() in
    db2look function mapping output
