> I have several large fixed record length files that I'm trying to load into a new db. My plan is to use a temporary table with one CHAR column to load the file, then use a second staging table to parse the fields and set appropriate data types. When I use the COPY command to load the temporary table I only get part of the record. When I encounter a FILLER column, which appears to be a NULL value, the rest of the record starting with the Filler doesn't load. Total record size is 455, at position 61 is the first filler field, defined as PIC X(1) from the legacy system. I'm able to load all the records in the file into the temporary table, but only for positions 1 through 60. When I looked at the flat file in TextPad, TextPad lists a special character at position 61 with a value as "NUL (^@ = 0 = 0x0)".

The COPY command does allow you to define the NULL character using the
WITH NULL AS attribute.
WITH NULL AS 'null string';
