min( )

Refines a WixDataAggregate to only contain the minimum value from each aggregation group.

The min() function refines a WixDataAggregate to contain the minimum value from the specified property for each aggregated group or from the whole collection if no group is defined.

When the aggregation is run, the returned WixDataAggregateResult object contains an item for each group with the following key:value pairs:

• If a value was passed for the optional projectedName, the key is named using that value. Otherwise, the key is named using the following format: "propertyNameMin", where propertyName is the name of the specified property.
• The value is the minimum value found in the specified property.

The following types of properties can be compared to determine a minimum value:

• Number: Compares numerically.
• Date and Time: Compares JavaScript Date objects.
• Text: Compares lexicographically, so "text" is greater than "Text".
• Rich Text: Compares HTML source as text.
• URL: Compares as text.
• Image: Compares image source as text.
• Video: Compares video source as text.
• Document: Compares document source as text.
• Reference: Compares by the ID of the referenced item as a String.
