Set Output Variable in Azure CLI task on VSTS

I am getting crazy to achieve this very simple task. I need to set an Output Variable in an Azure CLI task on Visual Studio Team Services, because next task in the Release definition will be executed according to the value of this variable.
I wrote this simple code

call az extension add --name azure-cli-iot-ext
call echo ##vso[task.setvariable variable=iotEdgeExists;]$(az iot hub query -n $(iotHub) -q "select * from devices.modules where devices.deviceId ='$(iotEdge)'")

which works, but not as exepected, in fact when I read the Ouput Variable in the next Azure CLI task and I try to print it on the screen I get the command string instead of the output...

call echo"$(az iot hub query -n <IOT_HUB> -q "select * from devices.modules where devices.deviceId ='<IOT_EDGE>'")"

What am I doing wrong?

If using Azure CLI version 2.* , you can use a powershell command rather than batch script wizardry. Microsoft's documentation found here

For example if you needed access token to update azure database it would look like so:

$token= & az account get-access-token --resource=https://database.windows.net --query accessToken
Write-Output("##vso[task.setvariable variable=sqlToken;]$token")

Don't forget to login first if testing locally:

az login

I've got some trouble (error code 255) with 

    FOR /F “tokens=* USEBACKQ” %%F IN (`az account get-access-token --resource=https://database.windows.net/ -query accessToken`) DO (
SET var=%%F
)
echo ##vso[task.setvariable variable=sqlToken;]%var%

So I used this (and that work for me)

for /f "tokens=1 USEBACKQ" %%F in (`az account get-access-token --resource=https://database.windows.net/ --query accessToken`) do echo ##vso[task.setvariable variable=sqltoken;]%%F

Inspired from the answer above but with some variation.

Works in an Azure CLI task on a Hosted Ubuntu agent in Microsoft DevOps as of July 2019.

This example runs an az command to fetch the full resource name of a storage account and sets it in the variable _StorageAccountNameVar for use in another pipeline task.

myvar=`az storage account list -g MyResourceGroup --query "[?contains(name, 'config')].name" -o tsv`
echo $myvar
echo "##vso[task.setvariable variable=_StorageAccountNameVar;]$myvar"

Refer to this code below:

call {your command}>tmpFile1
set /p myvar= < tmpFile1 
echo "##vso[task.setvariable variable=testvar;]%myvar%"

or 

FOR /F "tokens=* USEBACKQ" %%F IN (`{your command}`) DO (
SET var=%%F
)
echo "##vso[task.setvariable variable=testvar;]%var%"
