APAR status

• Closed as program error.

Error description

• When a block comment containing slash sign(s) '/' is inserted at
  the beginning of a statement, the following SELECT SQL fails
  with DB2 CLP.
  
  $ db2 -tvf jt_bad.sql
  /***************************************************************
  **************** Script Name : Comment Block Date :
  23/02/2016
  ****************************************************************
  ****************/ select  1 from sysibm.sysdummy1
  DB21034E  The command was processed as an SQL statement because
  it was not a
  valid Command Line Processor command.  During SQL processing it
  returned:
  SQL0084N  An EXECUTE IMMEDIATE statement contains a SELECT or
  VALUES
  statement.  SQLSTATE=42612
  

Local fix

• You can do one of the following options as a workaround.
  
  1? Remove the slash '/' inside comment block
  
  $ db2 -tvf jt_good_1.sql
  /***************************************************************
  **************** Script Name : Comment Block Date :
  23-02-2016
  ****************************************************************
  ****************/ select  1 from sysibm.sysdummy1
  
  1
  -----------
            1
  
    1 record(s) selected.
  
  2? Insert another statement before the SELECT query
  
  $ db2 -tvf jt_good_2.sql
  /***************************************************************
  **************** Script Name : Comment Block Date :
  23/02/2016
  ****************************************************************
  ****************/ set current schema = 'JIANTANG'
  DB20000I  The SQL command completed successfully.
  
  select  1 from sysibm.sysdummy1
  
  1
  -----------
            1
  
    1 record(s) selected.
