m3Tol (Function)

This converts the input given in cubic meters into liters.


<DOUBLE> unitconversion:m3Tol(<INT|LONG|FLOAT|DOUBLE> p1)

p1The value that needs to be converted from meters into liters.INT LONG FLOAT DOUBLENoYes

Example 1

SELECT unitconversion:m3Tol(1) AS liters;

This query uses the unitconversion:m3Tol() function to convert the value of 1 cubic meter into its equivalent value in liters. The conversion result is 1,000 liters.

Example 2

CREATE STREAM InputStream (volume_m3 double);
CREATE SINK STREAM OutputStream (volume_m3 double, volume_l double);

@info(name = 'volumeConversionQuery')
INSERT INTO OutputStream
SELECT volume_m3, unitconversion:m3Tol(volume_m3) AS volume_l
FROM InputStream;

In this example, an input stream called InputStream is created with a single attribute, volume_m3, representing volume values in cubic meters. Then, an output stream called OutputStream is defined, which will contain the original volume in cubic meters as well as the converted volume in liters.

The volumeConversionQuery processes events from the InputStream. It uses the unitconversion:m3Tol() function to convert the volume_m3 attribute from the InputStream into its corresponding value in liters, and this value is assigned to the volume_l attribute in the OutputStream.

The query outputs the original volume in cubic meters and the converted volume in liters for each event to the OutputStream.
