Question
This post we will talk about accumulation via millisec by using a unix timestamp transformation
In this use case, We will be working with a CData Elasticsearch ODBC driver and the client needs a way to accumulate a database of milliseconds.
Naively, we are unable to accumulate down to the millisec but with this work-around, we are able to do so.
Answer
This will be done upon data pull in from your data source where we will edit the query and transform it into a unix timestamp
Please keep in mind this is using a function from your native data source.
In this case, we are using ODBC CData and they support the function we needed for this transformation
By using the following function, we are able to bring in data and transform into unixts
Use this SQL code:
SELECT datediff('millisecond' ,DATEFROMPARTS(1970, 1,1),datetime)
FROM demosisense.testDate
After this has been completed, you can now go ahead and set the accumulation base off the new field we created. Following the regular Sisense function, we can then hide this field while doing an accumulative build on this.
And this will accumulate down to the millisec!
