What is the use of normalizer in Informatica?

The Normalizer transformation is an active transformation that transforms one incoming row into multiple output rows. When the Normalizer transformation receives a row that contains multiple-occurring data, it returns a row for each instance of the multiple-occurring data.

How do I add a port to normalizer?

To add multiple occurring ports in Normalizer transformation, double-click on the Normalizer transformation, and click on Normalizer. Add the columns in the Normalizer tab. You need to add the single and multiple occurring ports in the Normalizer tab.

How do I convert multiple rows to single row in Informatica?

Solution:

  1. Create a new mapping.
  2. Drag the source into the mapping.
  3. Create an expression transformation.
  4. Drag the ports of source qualifier into the expression transformation.
  5. Create the below additional ports in the expression transformation and assign the corresponding expressions:

What is Gcid and GKID in normalizer transformation?

The normalizer transformation has a generated column ID (GCID) port for each multiple-occurring column. The GCID is an index for the instance of the multiple-occurring data. For example, if a column occurs 3 times in a source record, the normalizer returns a value of 1,2 or 3 in the generated column ID.

Can we convert rows to columns using normalizer?

What is GK value in normalizer transformation?

What is normalizer set?

Is normalizer a subgroup?

Definition. Given a subset S of (the underlying set of) a group G, its normalizer N(S)=NG(S) is the subgroup of G consisting of all elements g∈G such that gS=Sg, i.e. for each s∈S there is s′∈S such that gs=s′g.

What is VSAM normalizer transformation?

The VSAM Normalizer receives a multiple-occurring source column through one input port. Pipeline Normalizer transformation. A transformation that processes multiple-occurring data from relational tables or flat files. You create the columns manually and edit them in the Transformation Developer or Mapping Designer.

What is GKID and Gcid in Informatica?

The GKID is used as a Sequence Generator. Therefore if there are three source rows, then the GKID will have values 1, 2 and 3. The GCID_* acts as a sequence generator for the fields with the occurs clause.

What is normalizer transformation in Informatica?

How many times does the normalizer return the data?

The Normalizer returns Hdr_Data and Store_Data once per row. The Normalizer transformation passes all columns to the Router transformation. It passes Detail_Data data four times per row, once for each occurrence of the Supplier_Info columns.
