What is the easiest way to convert a string to a float in the Azure Stream Analytics job service query? Unfortunately, I'm quite new to SQL, but only need this conversion applied to the CSV data stream.
This is what I get from the Test option on the query page...
'DeviceID','Temperature'
'20','30.8'
'20','32.1'
'20','31.5'
'20','28.2'
'20','29.1'
...when I use...
SELECT *
INTO TempPowerBI
FROM Tempiothub
... but in Power BI, the numbers can't be displaced. Instead, the amount of data is counted. So I guess the Stream Analytics query is the best place to convert the data.
Thanks a lot in advance ~

You can utilize CAST()
. Try This:
SELECT DeviceID , CAST( Temperature AS float) as Temperature
INTO TempPowerBI
FROM Tempiothub
