Add Columns

The Add Columns tool can be used to add a new column, based on an expression or formula.

Input, Output

Drag an Add Columns tool to your workflow canvas. Connect a downstream tabular-data output to the input of your Add Columns tool. Click it once to see the tool preview. Click it again to open and configure the tool.

Input	Output
Any single table	A single table with all original input columns and any new expression-based columns

Navigating Columns

On the right side, you will see your results table, it represents the output of the tool. On the left side, is the configuration panel. Column name is the desired column name of your output results. The plus sign allows you to add more than one new column.

Add a New Column

To add a new column from the results table, replace the default in the column name field, or you can leave it as the default of "New Column". You may also add a column description.

The Expression Builder, sits below the column description, this allows you to write custom expressions to create your new column.

Adding derived columns is key to advancing an analysis. The Expression Builder, baked into the Add Columns tool, is ideal for this task. It's potential is capped only by your imagination (and maybe your source data).

Use Expression Builder to:

• Write an expression based on the columns from the input table, in a simple math formula (as in the example above). See a list of Expression Operators supported by Analytics.

• Mark an entire column a Boolean True or False.

• Tag an entire column with a Text String or a Date Time.

• Reference a Parameter on your canvas.

• Write a Function, from wide selection of functions, including: Aggregate, Conversion, Datetime, Logical, Math, Table, and Text functions.

Hint: Use Enter to save and calculate anything you have written in Expression Builder. Be sure to save your expression before exiting the Add Columns tool.
