sort

Introduction

Use the sort instruction to sort data in the data extract. You can enter multiple columns to sort. The order in which you enter the columns is the order in which the columns are sorted. See the example below.

Creating a custom script transformation using the sort instruction

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

1. Create a custom script transformation.

2. In the Instruction step, select the sort instruction.

3. To configure the custom script instruction, fill in the following fields. Required fields are marked with an asterisk (*).

Key

Enter the name of the column to use to sort your data. Click to add another column to sort by, after sorting by the previous column(s).

Reverse

Select this field to sort the data in reverse. If left unselected, the data is ordered in ascending order.

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.
