mlTol (Function)

This converts the input given in milliliters into liters.

Syntax

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

Query Parameters

Name	Description	Default Value	Possible Data Types	Optional	Dynamic
p1	The value that needs to be converted from milliliters into liters.		INT LONG FLOAT DOUBLE	No	Yes

Example 1

SELECT unitconversion:mlTol(1000) AS liters;

This query uses the unitconversion:mlTol() function to convert the value of 1000 milliliters into its equivalent value in liters. The conversion result is 1 liter.

Example 2

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

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

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

The volumeConversionQuery processes events from the InputStream. It uses the unitconversion:mlTol() function to convert the volume_ml 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 milliliters and the converted volume in liters for each event to the OutputStream.
