Aggregates / maxDate

maxDate(dataset, columnIndex OR date, date...)

Finds and returns the maximum date in the given column of the given dataset, or the max value in a series of dates specified as arguments. When looking up the max date in a dataset, the column may be specified as an index or as a column name. Any null values in the column are ignored. If there are no rows in the dataset, null is returned.

 

For example, suppose you had a Table with this dataset in it:

AlertTime

Path

Severity

2010-01-08 7:28:04

Tanks/Tank5/TempHiAlert

4

2010-01-08 10:13:22

Tanks/Tank38/LoLevel

2

2010-01-08 13:02:56

Valves/Valve2/

2

 

You could use this expression to get the date and time for the most recent alert:

maxDate({Root Container.Table.data}"AlertTime")
