Custom Group Banding Count Method

Custom Group Banding Count Method is an advanced property that is hidden by default. For information on how to display this property, see Viewing and Changing Advanced VLDB Properties.

The Custom Group Banding Count Method helps optimize custom group banding when using the Count Banding method. You have the following options:

Treat banding as normal calculation (default): Select this option to allow the MicroStrategy Analytical Engine to perform the custom group banding.
Use standard case statement syntax: Select this option to utilize case statements within your database to perform the custom group banding.
Insert band range to database and join with metric value: Select this option to use temporary tables to perform the custom group banding.

Levels at Which You Can Set This

Database instance, report, and template

Examples

The following SQL examples were created in MicroStrategy Tutorial. The report contains a Custom Group "Customer Value Banding", which uses the Count method and the Revenue metric. The SQL for each of the three settings for this property is presented below. All three options start with the same SQL passes. In this example, the first six passes are the same. The remaining SQL passes differ depending on the Custom Group Banding Count Method setting selected.
