List,

I have a 6-position column, bdate, in a text file that I am trying to SQL*Load formatted as yymmdd. When I use the following SQL operations I get the following results:

1. SQL Operation: (bdate POSITION(001:006) CHAR
   "TO_DATE(:bdate,'YYMMDD')")
   Result in the database: Next Century, e.g. '300223' becomes '23-FEB-2030'
2. SQL Operation (bdate POSITION(001:006) CHAR
   "DECODE(:bdate,NULL,NULL,TO_DATE('19'||:bdate,'YYYYMMDD'))")
   Result in the database: Next Century, e.g. '300223' becomes '23-FEB-2030'

but when I take out the DECODE in item 2, I get the correct century. I only use decode because there are null values in this column. Can somebody explain to me what I am missing here?

Thanks,

George
