m3Tol (Function)
This converts the input given in cubic meters into liters.
Syntax
<DOUBLE> unitconversion:m3Tol(<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 meters into liters. | INT LONG FLOAT DOUBLE | No | Yes |
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
.
