ADF - Function to generate a new GUID

Question

I have a requirement to get a new GUID for every run of the pipeline. Is there any inbuilt ADF function which can generate a new guid for me ?

Thanks,
Kothai

Answer 1

I see guid() function that generates unique GUID documented in in below. Please try it -

ADF - control-flow-expression-language-functions

I also responded to your previous post here - adf-support-for-generating-a-new-guid.html

Have you seen the UUID function, available in a dataflow?

Answer 3

In Azure Data Factory (ADF), there is no built-in function specifically designed to generate a new GUID for every run of the pipeline. However, you can achieve this requirement by using an expression within ADF.

Here's an example of how you can generate a new free GUID using an expression in ADF:

1. Open your ADF pipeline in the Azure portal.
2. Select the activity where you want to generate the GUID, such as a copy activity.
3. In the properties pane on the right, find the field where you want to assign the new GUID.
4. Click on the field to open the expression builder.
5. Use the expression @guid() to generate a new GUID.

For example, if you want to generate a new GUID for a pipeline parameter named "runId", you can set the default value using the expression guid
