CALCULATE NEW COLUMN(S)

Category: Transform / Basic

Description

This action calculates one or more new columns using expression(s). One expression creates one column.

Use cases

Creating a calculated result from numeric values in two (or more) other columns.
Concatenating text values from two (or more) other columns.
Creating a full-column list of the same text or numeric value.

Action settings

Setting	Description
New column name	Enter the name of the new column.
Expression or Value	Options: It's an expression or It's a text or number. Enter the expression used to calculate the new column values, or, enter the text or numeric value that will be repeated for all values.
Position	Choose where the new column(s) will appear in the dataset. Options: Rightmost, Leftmost, or After column (and select the column the new column(s) will appear after).
If column already exists	Choose how EasyMorph reacts if the new column name already exists in the dataset. Options: Rename new column (a sequential number is appended to the column name), Do not create new column (the column is not created and the workflow continues), or Fail (the action displays an error and the workflow stops).

Remarks

The expression is calculated for every row. Other column values in the same row can be referred to by column names in square brackets. It's not possible to refer to other rows or tables.

Instead of an expression, this action can insert a full column of static text or numeric values.

Subsequent expressions can reference columns previously created within the same Calculate new column(s) action. (See example, below)
