Azure Sql Server 12.0.2000.8

• Import Database (from blob) UI
• az sql db import (from blob)
• SSMS 18.4, SSMS 18.12.1, SSMS 19.1 (Using Import BACPAC - local file system) from above indicated Windows machines

Steps to Reproduce:

Context: We are using Azure DevOps release pipelines leveraging SqlPackage to automate the export of an on-prem database as a bacpac into Azure Blob storage to enable manual (Azure UI) and eventually automated import of the bacpac into Azure Sql Server instances.

1. SSMS Task: Export Data Tier Application (Windows Server)
   _ Export to Azure Blob (Must be done in SSMS 18, this feature is currently broken in SSMS 19.1)
   _ Export to Local File System => AZ Copy to Blob
2. Import from Blob to Azure Sql Server

• Import Database (from blob) UI (works)
• az sql db import (from blob) (works)
  (These base cases would tend to indicate no underlying issues with the source database)

3. Windows Server => SqlPackage => Export to local file system
4. Windows Server, Windows 10 => SqlPackage => Import from local file system

• Targets
• -Local Sql Server (Works)
• • Azure Sql Server (Works)
    (These base cases would tend to indicate there is no corruption with the SqlPackage generated bacpac)

5. Windows Server, Windows 10 => SSMS (any version) => Import Data Tier Application (FAILS w/ Error Message below)
6. Azure Sql Server

• Import Database (from blob) UI (FAILS w/ Error Message below)
• az sql db import (from blob) (FAILS w/ Error Message below)

Error Messages from Azure UI Import or az cli import

---

The package file provided was not able to be opened. Please run SqlPackage locally to ensure that the file is not corrupt and please ensure that it uploaded to Azure Storage completely.

---

Based on where the stack trace in the error, a web searches show a possible issue that might be related whereby:
ZipIOLocalFileBlock validation reports corrupted file while System.IO.Compression does not

Lack of useful documentation and useful error reporting has not allowed me to conclude if there is a resident issue with the source database at fault, a database/server/source/target version or framework mismatch combability issue, or if the failing use cases noted above are representative of bugs in sqlpackage or ssms/azure cli api.

Did this occur in prior versions? If not - which version(s) did it work in?

This was not a regression (for us) as this is the first attempt at executing the above work flows that are failing.
All SqlPackage/SSMS versions used are detailed above

Tracking down the 140 version of SqlPackage has mitigated the error detailed in the OP.
It appears a compat issue between standard and core versions of sqlpackage and their mating compatability to current ssms/azure implementations or bacpac import. It is still unclear if this is an actual bug, or a poorly handled compatibility issue. It is none the less problematic that core versions of this product produce (apparently valid) bacpacs that cannot be imported via ssms or azure api's.

Hi @bryanhunwardsen This issue resides in the System.IO.Packaging library and we have opened an issue dotnet/runtime#94899

[zijchen]

There are a few compatibility issues with packages generated from .NET Core and the .NET Framework version of DacFx. The recommendation is to use the same version for both import/export. SSMS uses the .NET Framework so if you would like to use it for import, please use the sqlpackage.exe installed from the MSI.

Worth noting that SSMS doesn't always use the latest version of DacFx so there might be some issues with using an older version for import. Ideally we recommend just using the same sqlpackage for both operations.

@zijchen, We use SqlPackage to automate the export of an on prem db followed by azopy to Azure Storage.
We need to automate the import of the bacpac from Azure Storage into an Azure Sql Server.
This cannot be done with SqlPackage(to the best of my understanding) as it does not support Azure Blob as a source target for import. Until then, we are forced to rely on the Import implementation exposed via the AZ Cli (Short of re-copying the bacpac to an Azure VM whereby it can be targeted for Import via a version matched SqlPackage installation - This work-around is sufficiently un-desired as to be only a last case scenario). It would be preferable for the bug fix, so that we may avail ourselves of the current development benefits: in our case the Core version is operating 3x faster on export and import than MSI version, if for no other reason.

Updating here to acknowledge that this has been added to documentation as a known issue:

• https://learn.microsoft.com/en-us/azure/azure-sql/database/database-import?view=azuresql&branch=main&tabs=azure-powershell
• https://learn.microsoft.com/en-us/sql/tools/sqlpackage/release-notes-sqlpackage?view=sql-server-ver16

We are working towards a solution such that bacpacs created with the SqlPackage CLI and other .NET applications can be imported by .NET Framework variants (including the Import/Export capabilities of the Azure portal, Azure PowerShell, and SSMS). Because of the dependency on a fix in .NET, I wanted to be transparent that leveraging a workaround is advised. I'm happy to chat 1:1 with folks on specifics to your environment to find the least ugly solution. (you can reach me on this topic at drskwier@microsoft.com)

this is fixed in .NET SDK 8.0. Please install the latest runtime v8.0.7 and install sqlpackage with dotnet tool. dotnet tool install -g Microsoft.SqlPackage if you import database with sqlpackage now, the new package can be exported using sqlpcakge that is installed with the MSI
