Using conditions, loops and parallel execution allows developers to implement much more complex Enterprise Integration scenarios using Azure Logic Apps. All those actions are available through Control Actions group which we will learn all about Today.
In this episode I will cover basics of Logic Apps Control Actions with live demo of parallel execution, conditions, loops as well as terminate and scope actions.

Hey Adam, one of the things I love the most about your video is that you create all logic aps from scratch every time! and you also show step by step every time. This allow us to learn by repetition! Very good method. I can't wait to see the new videos you'll be creating!

@AdamMarczakYT 4 года назад

I appreciate that!

@arulmouzhiezhilarasan8518 4 года назад

Thanks Adam! Your valuable explanations with step by step demo, really makes us much more easy to understand and working with Azure. I have tried each things that you have explained in this video practically and it really helped me to thing in many ways for problem solving in Azure.

@harshit7577 2 года назад

Hi Adam, I understood the concept, It is really helpful. I have another scenario that how one logic app performs multiple action one by one, how to achieve it? so for example LA first calls to Parsing Azure function (that azure function can call another azure function ) and pass the result to LA and 2) step LA need to validate the data and if it is ok than 3) step need to store in blob so how to achieve this? your gaudiness? Thanks!

@sindhukontham6993 Год назад

Hey Adam, i have a doubt..when we wanna delete any blob in parallel or conditional execution, instead of list of file name why we are selecting list of file path? actually i tried with list of file name first and ended up failing. Wanna know the explanation behind it please.

@techwithazam6992 4 года назад

Great content Adam and very precise explanation! I have a use case in which I want to create a trigger on a collection of blobs created in a specific container, since generally even if we upload 3 files in a container, 3 triggers will be fired... i want to get one trigger fired, so that, in logic apps, I can read file names and addresses of all those files (let's suppose 3), and then to pass on these file names to data factory which reads these files and inserts in a database. Kindly let me know how such a multi-blob trigger can be created! Thanks

@AdamMarczakYT 4 года назад

Thanks. For batch processing simply click on the three dots "..." on the trigger and unselect spliton option. Once you do it trigger will return a list of blobs instead of one.

@mohanreddygottam9535 4 года назад

The video is very good and helpful. Thank You Are multiple conditions possible in Switch? I mean, while using switch how we can provide multiple conditions ( Ex: A=B or A=C and A=D)

@AdamMarczakYT 4 года назад

Thanks! Try doing parallel branches and checking in the branch for conditions. Switch always chooses only 1 path, not multiple ones. It works like that in all programming languages too.

It returns globally unique string. Check function reference for details: docs.microsoft.com/en-us/azure/logic-apps/workflow-definition-language-functions-reference#guid

@sibymathew1802 4 года назад

Hi Adam, 4 clarifications : - In parallel executions, would there be a race condition when trying to delete a blob and use the same entity variable to create a log in parallel ? Would there be any benefit in assigning these values to a variable before using it in parallel ? - You had copy/pasted guid() directly into the field at 11:41 . I think this will not work if its not added to the "Expression". Am i right ? - In the "Until" control there is an option: "Count" within settings. By default this value is 60 and should be increased if our loop goes beyond that. - I suppose "Scope" would not be transactional, in the sense reverting any change if an entity has failed within ? Thanks again for your wonderful videos..

@AdamMarczakYT 4 года назад

Variables are globally scoped so you shouldn't use them in parallel or in parallel loops. If you need local variables use 'compose or parse json' actions or simply call separate logic apps in parallel. Expressions that are pasted directly into the field must be properly formatted. As an excersise copy guid() expression from a field and paste it into notepad, you will see that text was escaped via expression brackets like so @{guid()}. Count in until i maximum amount of loops to ensure you won't do infinite loops by mistake. Scope is just like try/catch in a programming language. Scope is a try block.

@sibymathew1802 4 года назад

@@AdamMarczakYT Thanks for the clarification.. so you mean even though you pasted guid() inside the field it would work..?

@AdamMarczakYT 4 года назад

I think this no longer works like that. You need to paste either "guid()" string into expression box or paste full escaped expression into the field "@{guid()}".

Adam, from my personal account, can I create App Registration and use it in Azure Logic Apps to communicate with Azure Analysis Service. Or do I have to have a tenant of my own?

@satyateja688 4 года назад

Adam, very well explained. I have scenarios like multiple approval processes using logic apps. I have 2 approvers everyone should approve. if anyone has rejected, the request got rejected. I have been tried for single approval it is working fine. could you give me some inputs for the multi approval process?

@AdamMarczakYT 4 года назад

Logic App approval flows are very simplistic. You need to built that logic yourself. I probably would use parallel action block and send two approval emails. If they both complete then it's approved. If one of them is completed I'd check if it was rejected, in which case I'd finish the run earlier. It can be done.

@tipums123 3 года назад

Nice video Adam! Can I use "When a file is added or modified" to check multiple folders for a new file?

@AdamMarczakYT 3 года назад

Blob storage doesn't have folders. It's a flat hierarchy of files in a container. If your file name consists slashes like /demo/test/myfile.csv then demo and test will be displayed as folders but they are not folders, just virtual ones. So setting when file is added or modified then it will work for all files and virtual folders in the container. Thanks for watching :)

Hi, I am struggling to create logic app, which is having http request and in request we need to decide whether to read request or write request

@AdamMarczakYT 4 года назад

What kind of issue are you having?

@snehalgawari4258 4 года назад

@@AdamMarczakYT Hello Adam, thank you so much for reply, Request which we are going to make to http are : 1. Read from Db 2. Write to Db For now passing one element which checks json element RequestType, -Read or -write At payload I have passed json for write request So true part is getting executed At false part I am expecting to execute read json but as payload is different it is throwing bad request which is obvious .. Still finding out ways

@AdamMarczakYT 4 года назад

You can supply JSON schema to HTTP request body so that RequestType is available in later steps as variable or use TriggerBody() expression and get RequestType from it. It would probably be something like TriggerBody()?['RequestType'] (typing from memory so might be incorrect). And then simply do condition on it. Best of luck!

@gopinathrajee 4 года назад

Just so that others are also aware. The Logic App UI is not good at simple error checking. The different emails allowed are Office365 and Outlook. Outlook here means either outlook.com or hotmail.com. I was testing with my hotmail id and later had to switch to gmail to play with send and recieve ids. It took me quite sometime to figure out the app is not working because I had my gmail account. The app even did not error when I added the gmail account and when it executed. I spent several hours troubleshooting only to realize my silly mistake!!

@AdamMarczakYT 4 года назад

Yea! A common mistake indeed :) I think this one was returning unauthorized issue which indeed is a not so well descriptive. Thanks for sharing your case with others here ;)

@@AdamMarczakYT From the Output, how do we capture various parts of it into variables that can be further used in the next step? The next step is a an Email Action step that would send out emails mentioning that it connection succeeded or failed. If it succeeds, in the output portion of the window, I get a status code of 200 along with a some json string in the Body section. Is there a way to capture these two and use them in the email step?

@AdamMarczakYT 4 года назад

To parse outputs into variables use Parse JSON action or initialize variable action, parse json is more suited to your scenario. To build your own objects (complex types) use compose action.
