Select In-DB Tool
The Select In-DB tool selects, deselects, renames, and reorders fields in an In-DB workflow.
Use the Select In-DB tool to limit the amount of fields in an In-Database data stream. In many cases, limiting the amount of data passing through a workflow can significantly improve performance. Other common use cases for the Select In-DB tool include renaming and reordering columns.
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, see In-Database Overview.
