I have written a script whose end task is to insert data into a postgreSQL database. I am having trouble trying to insert a null date value when the field type is date and there is no date listed in that record's field. I've tried to construct an if/else statement, but the word null seems to wreck things. I tried using undef and the script did not run using it.

I've tried it this way (including omitting the length):

$flds[6] = (length($flds[6]) == 0) ? 'NULL';"\'$flds[6]\'";

and I've also tried it this way (including adding length):

if ($flds[6] eq '')
  {
    $flds[6] = NULL;
  }
else
  {
    $flds[6] = $flds[6];
  }

My error message either says bad external date representation or there is a syntax error near null. I've tried changing the quotes around and using upper and lowercase letters.

Any help would be greatly appreciated. Please let me know if I haven't provided enough information
