IoT Time Series Aggregates Service – Selecting¶
Select Syntax¶
With the optional select
parameter one can define which data to return. The value of the select
parameter is a comma separated list of requested data. Each value in the list can either be a variable name or an aggregated field using a variableName.fieldName
syntax. The field name can be one of the following:
countgood
countuncertain
countbad
sum
average
mintime
minvalue
maxtime
maxvalue
firsttime
firstvalue
lasttime
lastvalue
sd
If no select
parameter is specified, all variables and fields are returned. If a variable is specified, but no field name, all the fields for that variable are returned. If a variable and field name are specified, only that field of the variable is returned. Variable names are case-insensitive.
