This step calculates checksums for one or more fields in the input stream and add this to the output as a new field.
The Add a Checksum step has the following options:
|Step name||Specify the unique name of the Add a Checksum step on the canvas. You can customize the name or leave it as the default.|
Specify the type of checksum you want to calculate. The available types include:
If you specified MD5, SHA-1, or SHA-256 in the Type option above, you can select one of these result types:
|Result field||Specify the name of the field that contains the checksum.|
|Compatibility Mode||Select for backward compatibility of the step with transformations created before PDI version 4.2.0 and its inherent hexadecimal encoding issue.|
|Old Checksum Behaviour Mode||
If checked, the incoming fields will be treated as strings
NoteA binary field type will produce the string representation of a byte array.
If unchecked, all incoming fields will be treated as byte arrays.
|Field||In the table, specify which fields you want read into the transformation from the CSV file.|
|Get Fields||Click Get Fields to have the step populate the table with fields derived from the source file. All fields identified by this step will be added to the table.|
