Description |
|---|---|
|
skip |
An integer number of matching rows to skip before returning any rows. Defaults to 0, meaning no rows are skipped. |
|
onCollect |
This parameter can be set to yes or no. If this parameter defaults to yes, only points that are currently being collected are returned. If this parameter is set to no, all points that have been placed on collect are returned. However, the name of points that have been recently placed on collect (new points) are not returned. This is because data for new points does not yet exist in the Historical database. |
