Can't query partitioned tables - Azure Synapse Link for Dataverse

Leo Milos 10

Hi, we have a problem with accessing partitioned tables in Azure Synapse Workspace that were previously created by ingesting tables from Power Platform via Azure Synapse Link for Dataverse. Snapshot folder and .csv files are normally created but can't be accessed via partitoned tables.

For some reason we get message : Invalid object name 'dataverse_********.dbo.opportunity_partitioned'.

Also there are no views created in Dataverse for Snapshot tables, we thought this should be automatically created when Creating Azure Synapse Link for Dataverse.

Thanks for the help!

Hello Leo Milos,

Welcome to the MS Q&A platform.

Can you please confirm if you have the issue on the specific partitioned or all partitioned tables?

Views supported to be created. Sometimes it will take time for the views to get created for the partitioned tables.

Hi,

we have an issue with all partitioned tables, they haven't been created and a couple of days passed since creating Synapse Link.

Hello Leo Milos,

I had a chat with the product group, and they are looking for workspace details like name, region, issue start time, etc., to troubleshoot the issue further.

If you have a support plan, please open a support case so the support engineer can collect these details and work with the PG.

If you don't have a support plan, please let me know so I can enable one-time free support for you to work on this.

I am looking forward to hearing from you.

I'm currently facing the exact same problem.
Setup: Dataverse synapselink standard configuration (in-place updates) // West-Europe

All files are created correctly (including the snapshot folders).
Near-realtime external table is working.
I also see an external table for the snapshot data. But when I try to query it, I get the same error.
I don't see any views in SSMS, so there seems to be something wrong there..

I unlinked and relinked again, but still have the same issue.

Hello Johan Hostens,

Thanks for your comment. It seems like there was an issue in the metadata sync process responsible for syncing data from DataVerse to the Serverless instance.

To troubleshoot the issue further, we need workspace details like name, region, issue start time, etc.

If you have a support plan, please open a support case so the support engineer can collect these details and work with the PG.

If you don't have a support plan, please let me know so I can enable one-time free support for you to work on this.

I am facing the exact same issue when querying partitioned tables, like what was mentioned by Johan Hostens. Has this issue being resolved?

I have the exact same problem, would really appreciate some help with this please?

I tried the "credential" solution below but this did not work.

We're able to query our non-partitioned tables fine, but the partitioned tables error with:

"Failed to execute query. Error: Invalid object name..."

Surely these should just work straight away as part of the Synapse link setup?

@Tzee Chen , This fixed the issue for me:

Check if Workspace System Assigned Managed identity has Storage Blob Data Contributor access on the Storage Account. --> This was ok in my case

Create a server-scoped credential on the master database for the storage account and container

--On master database CREATE CREDENTIAL [https://storageaccount.dfs.core.windows.net/container] WITH IDENTITY='Managed Identity'

--> After creating the server-scoped credential the partitioned tables started working.

Hmm can't get it to work.

I suppose I have to replace

storage account with my storage account

container with the container that is being used

and Managed Identity with the managed identity assigned to the Synapse workspace ?

Both of these are set for mine and still can't see the external tables.

Thank you for sharing this. I was running into the same issue and then it appears that creating the credential in the master database resolved it. Thank you very much for posting this.

Not for me. I can see them in Azure but not SSMS with same account. Must be something in addition that needs to be done.

Unfortunately for me it still does not work. I have created the credential like this (which works fine):

CREATE CREDENTIAL [https://mystorageaccount.dfs.core.windows.net/mycontainer]WITH IDENTITY='Managed Identity'

However when I try to query a partitioned table using the master databse int eh built-in serverless sql pool I get this error:

Content of directory on path 'https://presalestestusers.dfs.core.windows.net/dataverse-presalestest-unqf8fe93ad29b7471599034eb9c7323/logisticslocation/createdonpartition=/.csv' cannot be listed.

What am I doing wrong?
