Some tips and tricks.
Exporting data from DB2 to files in linux (I like EXPORT but you also can use UNLOAD or a simple SELECT and the redirection >):
$ db2 EXPORT TO “/tmp/unload.txt” OF del MODIFIED BY COLDEL, CHARDEL* SELECT * FROM MYTABLE
This command will export the table MYTABLE to the file /tmp/unload.txt formatting the fields like *COL1*,*COL 2*,*COL NUM 3*,…,*COL N*
In MacOSX formatting the files from UTF-8 format to ISO-8859-1 format (because the special spanish chars áéíóúñ…):
$ iconv -f UTF-8 -t ISO-8859-1 unload.txt > unload_8859.txt
