splitfield

splitfield#

Split values in one column into new columns using a regular expression.

Note

This guide explains how to configure the splitfield instruction. To learn about another instruction, go back to the Custom scripts available in Adverity overview.

Introduction#

Use the splitfield instruction to split the values in one column into new columns. Use a regular expression to determine how the values are to be split.

Creating a custom script transformation using the splitfield instruction#

To create and configure a custom script using the splitfield instruction, follow these steps:

Create a custom script transformation.
In the Configuration step, select the splitfield instruction.
To configure the custom script instruction, fill in the required fields below, as well as any optional fields you require:

Field (required)

Enter the name of the column that contains the values to split.

Pattern (required)

Enter a regular expression used to split the values into new columns.

New fields (required)

Enter the names of the new columns to populate with the split values.

Include original

Select this field to keep the column from which the values are split.

Maxsplit

Enter a number for the maximum number of times a value can be split. Any values that can be split are left combined in the last column of the data extract (see the example below). Enter 0 to not provide a limit.

Flags

Enter a flag for the regular expression. A regular expression flag is used for global and case-insensitive searching.

Subtable

Enter the name for a subtable that you want to use within this custom script.

A subtable is a temporary table that only exists for this custom script. You can apply additional instructions within the same custom script to the subtable. However, the subtable cannot be used in any other custom scripts.

If a subtable does not exist for the current custom script, the transformation is applied to the data extract, and the enriched data is output into the subtable. If the subtable already exists for the custom script, the subtable is used as the input for the transformation and optionally as the output.
