transpose

Swap the positions of rows and columns in a data extract.

Introduction

Use the transpose instruction to swap the positions of rows and columns in a data extract. The values in the rows of the first column are used to name the transposed columns.

Creating a custom script transformation using the transpose instruction

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

1. Create a custom script transformation.

2. In the Instructions step, select the transpose instruction.

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

Row limit*

Enter the number of rows to be transposed. All rows after this limit are removed from the data extract.

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.
