Select In-DB Tool

Last modified: May 04, 2022

Use Select In-DB to select, deselect, rename, and reorder fields in an In-DB workflow.

Use the tool to limit the number of fields in an In-Database data stream. In many cases, limiting the amount of data passing through a workflow can significantly improve runtimes and performance. There are other common use cases for the Select In-DB tool as you can rename and reorder data fields, and change field data types.

In-Database enables blending and analysis against large sets of data without moving the data out of a database and can provide significant performance improvements over traditional analysis methods. For more about the In-Database tool category, visit In-Database Overview.

Configure the Tool

Use the table to modify the incoming data stream. Each row in the table represents a column in the data.

Select, Deselect, and Reorder Columns

To include a column in data, select the check box to the left of the column name. Deselect the check box to exclude the column.

To reorder the columns of data...

  1. Select to highlight a row, or drag down to highlight multiple rows.
  2. Use the up or down arrows, or right-click and drag, to move the rows to a new location.

The Unknown column is selected by default. It allows new columns in the data. Move the column to the location where you want a new column to be.

Rename a Column or Add a Description

  • To change the name of a column, select Rename and enter the new name.
  • To add a description, select Description and enter a description.
