Aggregate Column Attributes
The attributes for the Aggregate Column element are described below:
Aggregate Column

Aggregate Function |

- Average
- Concat (see section below)
- Count
- Distinct Count
- Max
- Median
- Min
- Mode
- Std Deviation
- Sum
Columns with Null values are excluded by default. If you want them to be included, create the constant rdCalculationsIncludeNulls and set it to True. |
ID |
(Required) The unique element ID for the Aggregate Column element.
|
Concat Separator |
The character used to separate concatenated text values, if any. Default: comma |
Data Type | The data type of the column named in the Aggregate Column attribute value. |

The Concat Function
The Concat function builds a string of concatenated values by taking all the text in the specified data column and concatenating it together using the default (a comma) or specified separator character.
This can be useful for a variety of purposes, including creating default values for select lists.
