The Expression Editor also displays the following functions:
  • Transformation language functions.
    SQL-like functions designed to handle common expressions.
  • User-defined functions.
    Functions you create in PowerCenter based on transformation language functions.
  • Custom functions.
    Functions you create with the Custom Function API.
