The add column transformation creates a new column derived from existing columns using a simple expression.

When to Use

  • Concatenate first and last name into full_name.
  • Compute a value (e.g. total = quantity * price).
  • Add a constant (e.g. source_system = ‘erp’).
  • Extract part of a value (e.g. year from date).

Example

Add full_name as first_name + ' ' + last_name:
first_namelast_namefull_name
JohnDoeJohn Doe
JaneSmithJane Smith

Configuration

Specify the new column name and the expression. The expression can reference other columns. Syntax depends on the pipeline engine.
