Generated keys

Generated keys

The Normalizer transformation generates key values for normalized data.
Generated keys fields appear on the
Normalized Fields
tab when you configure the field to have more than one occurrence.
The
mapping
task generates the following fields for normalized data.
Generated Key
A key value that the transformation generates for the first group-level field or the first multiple-occurring field. The transformation also generates a key value for all multiple-occurring groups with at least one multiple-occuring child group or field.
The naming convention for the Normalizer generated key is GK_<redefined_field_name>.
When the first normalized field is a multiple-occuring group that contains a multiple-occuring child field or group, the Normalizer transformation generates two key values for the parent group. The transformation appends the second generated key with "_1"
The generated key is not applicable in advanced mode.
Generated Column ID
A column ID value that represents the instance of the multiple-occurring data. For example, if an Expenses field that includes four occurs, the task uses values 1 through 4 to represent each type of occurring data.
The Normalizer transformation uses a generated column ID for each field configured to occur more than one time.
The naming convention for the Normalizer generated key is GCID_<redefined_field_name>.
An
advanced cluster
processes the generated column ID field as a bigint. The Data Integration Server processes the ID as an integer.
