‍‍hi everyone,
       I have a so big db2 table which contains many char type columns.[see 
1.png]
       I've always been tring  to extract datas to hive via sqoop to fullfill 
different demands.

       In the past time, I try to manually trim all the char type colums when 
write Hivesql[see 2.png]

       There are so many colums to trim that I always forget some of them,just 
like following:

        suppose BANK_TABLE is the target table of hive,and 2323423232323 is an 
existing  card number in the table.‍
---------------------------------------------------------------------------------------
      if I execute: hive -e "select * from  BANK_TABLE where 
card_no='2323423232323' " ‍
---------------------------------------------------------------------------------------
       The result is nothing owning to I forget to trim the column: card_no 
when I write sql to import data to hive.
       So I wonder is there a good way for sqool or for hive to do the 'trim' 
automatically?

Thank you all!
