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

  "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:
  SQL0104N  An unexpected token "VARCHAR" was found following
  "IBM.TIMESTMP,
  SYSIBM.".  Expected tokens may include:  "LONG".  LINE NUMBER=1.

  "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

  DB20000I  The SQL command completed successfully.
  

Local fix

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