@prithvi.sriramprasad - Thanks for the question and using MS Q&A platform.
If your query fails with the error File cannot be opened because it does not exist or it is used by another process and you're sure that both files exist and aren't used by another process, serverless SQL pool can't access the file. This problem usually happens because your Microsoft Entra identity doesn't have rights to access the file or because a firewall is blocking access to the file.
By default, serverless SQL pool tries to access the file by using your Microsoft Entra identity. To resolve this issue, you must have proper rights to access the file. The easiest way is to grant yourself a Storage Blob Data Contributor role on the storage account you're trying to query.
For more information, see:
- Microsoft Entra ID access control for storage
- Control storage account access for serverless SQL pool in Synapse Analytics
For more details, refer to Troubleshoot serverless SQL pool in Azure Synapse Analytics.
