REST API ExecuteQueries

ExecuteQuery.png

Hi ...I am new to BI & DAX . Please help me to have a better understanding. I have the a data table (given above) from which I should retreive the latest single record based on SensorId through API's. The POST ExecuteQuery API with below body gives me a list of values. How can I get only a single latest  record ?  TIA
"queries": [
{
"query": "EVALUATE FILTER(ALL(usecase[Time],usecase[Telemetry],usecase[SensorName],usecase[SensorType],usecase[SensorID]),usecase[SensorID] = 475601) ORDER BY usecase[Time] desc"
}
],
"serializerSettings": {
"includeNulls": true
}
}

Hi @Anonymous ,

If you want to get only the latest value you can use TOPN in your query
e.g. 
EVALUATE TOPN(1,FILTER(ALL(usecase[Time],usecase[Telemetry],usecase[SensorName],usecase[SensorType],usecase[SensorID]),usecase[SensorID] = 475601) ORDER BY usecase[Time] desc)

I hope this post helps to solve your issue and if it does consider accepting it as a solution and giving the post a thumbs up!
