Set Octopus output variable from sql script

Question

I created octopus ranbook and one of the steps is run sql script. I need get result from sql procedure and set it to output variable which value I need to use on second step. When I try set output variable like Set-OctopusVariable -name "Name" -value $result right after sql script it fails because octopus try execute it like sql. I use SQL - Execute Script template and looks like I can't mix sql code and Set-OctopusVariable together. Can someone help with this issue

Tried use Set-OctopusVariable. Sql script works correctly, I logged results and it's ok, but I can't get it on another step of ranbook

The variable values are passed back from the task log to the server via an Octopus service message.

You can just use the PRINT command to write a formatted message, however, the values passed to the service message need to be base64 encoded.

Create a sql function to convert the values to base64:

CREATE FUNCTION ConvertToBase64 (@Input VARCHAR(MAX))
RETURNS NVARCHAR(MAX)
AS
BEGIN
   RETURN (
       SELECT CONVERT(VARBINARY(MAX),@Input) FOR XML PATH(''), BINARY BASE64
       );
END

Then in your sql script you can write the service message:

DECLARE @name NVARCHAR(MAX) = (SELECT [dbo].ConvertToBase64('varname'))
DECLARE @value NVARCHAR(MAX) = (SELECT [dbo].ConvertToBase64('varvalue'))

PRINT '##octopus[setVariable name=''' + @name + ''' value=''' + @value + ''']'

As long as the sql execution output is currently being written to STDOUT it will end up in the task log and should produce a variable output.
