I'm using this: COPY( select field1, field2, field3 from table ) TO 'C://Program Files/PostgreSql//8.4//data//output.dat' WITH BINARY To export some fields to a file, one of them is a ByteA field. Now, I need to read the file with a custom made program. How can I parse this file? BTW: I cannot export as CSV, because the binary data is modified when I do that. -- Leonardo M.
