PX Sequential Files

Fixed width

[ray.wurlod]

Then, as noted earlier, any null field value that you supply must have the same width as the field would if it contained a non-null value. For example if the field is Char(4), then an acceptable null field value might be "####" or something of that kind (even four spaces). The null field value property informs DataStage when reading this file that, if the indicated value is encountered, to import NULL. Or, when writing to the file, when NULL is received on the input link, to write this value into the field.
