Connector MS SQL Server - sp output variable

zsery 3 years ago in Studio / Variables updated by Elmo 3 years ago 3

Variable is declared (stored procedure) as output only. Studio needs declare as input too, why?
Response exists but MS SQL connector does not retrieve value in this variable (response  empty), why?

Generate mapping functionality generate only recordset mapping, it is correct< Is not missing mapping for output variable from stored procedure?

SignalR Connector

Anonymous 5 years ago in Studio / Variables updated by Gandalf 5 years ago 6


I have a SignalR hub with some data that I want to set into warewolf variables and then use this variable value either to store or call other services/web api as a trigger.
Do I need to create a connector to accomplish this behavior?

In order to monitor this variable value, do I need to put this variable within a loop?

Hi victor

Make the call to the URL of the service (Look above the workflow for this). Something like this:

In this example I have a folder called Examples with a workflow called Handler in it which is the workflow you can see on the design surface. In the Variables list on the right, I have set the two variables I want to use as Input so they can be accepted by the workflow. After that, I just use them, as in the decision.

Hope that helps.

Not a bug

Recursive Evaluation

Anonymous 6 years ago in Studio / Variables updated by Gandalf 5 years ago 5
After reading about how the Datalist caters to recursive evaluation I thought this was interesting and wanted to try it out.
From the technical documentation page:
"i.e. [[hello[[world]]]] would be recursively evaluated as [[hellobob]] where [[world]] had the value of “bob” and then [[hellobob]] as “my name is bob” where [[hellobob]] had the value “my name is bob” stored in it.

I decided to test this out myself. I created a variable [[hellobob]] and assigned the string "my name is bob" Then I created a variable [[world]] and assigned "bob". Finally I created a variable [[result]] and assigned [[hello[[world]]]]. To my disappointment I received a parse error.

I went back and added the variable [[hello]] and assigned "hello"
And then changed my assignment of [[result]] to [[[[hello]][[world]]]]
This produced the expected result. In the debug window it read my assignment as Variable [[result]] = New Value [[hellobob]] with the string "my name is bob" as its value.

I don't know if this is technically a bug since it did behave in a recursive manner when I tried the second time, but perhaps the documentation is wrong. When I set [[result]] to [[hello [[world]]]] It returned [[hello bob]] an unassigned variable. But with no space there, [[hello[[world]]]] results in a parse error.

As part of our architecture framework for WareWolf development, I need to come up with a set of naming conventions for variables(inputs or outputs) in WareWolf workflows.

Can you suggest a naming convention for WareWolf workflow variables(below are my thoughts):

-For input variables (eg . WorkflowName_In_Variablename)

-For output variables (eg . WorkflowName_Out_Variablename)

-For variables from other workflows that kick off other work flows (eg . WorkflowNameParent_WorkflowName_In_Variablename)

most languages have keywords / built in functions.
getdate() for SQL or DateTime.Now for c#
How can I get the current time when processing an activity/decision/etc
Also Im sure there are other common things Im going to want todo. Be great to have this somewhere

Hi Paul

Warewolf is a Flow based language. Think about a typical coded function being a workflow and each service or tool in that workflow being a line or action.

So, if you are after the time, we need to execute a tool to get the time into a variable and then use it.

There are a few ways to get the current system time:
1. The calculate tool has all the MS Excel funcitons so you can just tupe: now() and then put that result into a variable.
2. The Assign tool can act like a Calculate tool if you start the assign value with an = so you can just type: =now()
3. The Gather System Information Tool has a Date & Time option
4. Date and Time Tool: If you leave the Input blank and the Input format blank, by default the tool will return the current system time in the system format.

I hope I have answered your question.
