Example 1


In this example, the unitconversion:kgToST() function converts a value of 1000 kilograms into its equivalent value in US short tons. The conversion result is approximately 1.10 short tons.

Example 2

CREATE STREAM InputStream (mass_kg double);
CREATE SINK STREAM OutputStream (mass_kg double, mass_st double);

@info(name = 'massConversionQuery')
INSERT INTO OutputStream
SELECT mass_kg, unitconversion:kgToST(mass_kg) AS mass_st
FROM InputStream;

In this example, an input stream called InputStream is created with a single attribute, mass_kg, representing mass values in kilograms. Then, an output stream called OutputStream is defined, which will contain the original mass in kilograms as well as the converted mass in US short tons.

The massConversionQuery processes events from the InputStream. It uses the unitconversion:kgToST() function to convert the mass_kg attribute from the InputStream into its corresponding value in US short tons, and this value is assigned to the mass_st attribute in the OutputStream.

The query outputs the original mass in kilograms and the converted mass in US short tons for each event to the OutputStream.
