SQL MI Restore with valid SAS key failing with Operating System Error 86
We will provide details about a workaround for resolving the "Operating System Error 86" encountered during database restoration from Azure Storage on SQL Managed Instance. In this scenario, the Storage Account was not behind firewall and the credential already had a valid SAS token.
Azure SQL Database idle sessions are killed after about 30 minutes when "Proxy" connection policy
Let's see how the connection policy affects the idle sessions on our Azure SQL Database connections.As we will see, the Azure SQL Gateways will kill idle sessions after 30 minutes when "Proxy" connection policy is set.How to Change Collation of an Azure SQL Managed Instance When There Are Dependency Errors
In this article, I will explain how to change the collation for your Azure SQL Managed Instance when the following scenario is encountered: You try to change the database collation with the following T-SQL: USE [master] GO ALTER DATABASE [testdb] COLLATE SQL_Latin1_General_CP1_CS_AS GO And it fails with the following message: Msg 5075, Level 16, State 1, Line 24 The column 'tablex.colx' is dependent on database collation. The database collation cannot be changed if a schema-bound object depends on it. Remove the dependencies on the database collation and then retry the operation. Steps in brief: Export the database to bacpac using SQLPackage. Modify the collation by editing the model.xml file. Import the database using SQLPackage and overriding the model.xml path. Change the database name or modify app connection string to use the new database. Considerations: Schedule a maintenance window for your application during the process and stop the workload to prevent data loss. Ensure you have the latest SQLPackage version: Download and install SqlPackage - SQL Server | Microsoft Learn Review the different connection strings depending on the connection method outlined in these examples: SqlPackage Export - SQL Server | Microsoft Learn This article applies to Azure SQL DB and Azure SQL Managed Instance. Steps in details: Start the maintenance window for your application. Export the database using SQLPackage: sqlpackage.exe /Action:Export /ssn:tcp:<ServerName>.database.windows.net,1433 /sdn:<DatabaseName> /su:<UserName> /sp:<Password> /tf:<TargetFile> Rename the *.bacpac file to *.zip so you can open it with the file explorer: Copy the model.xml to a local folder “C:\Temp\model.xml”. Edit the “C:\Temp\model.xml” with the desired collation and save the file. For example: <Property Name="Collation" Value="Thai_CI_AS" /> Rename the file extension modified in step 3 from *.zip back to *.bacpac. Run the import using sqlpackage.exe. Use the flag /ModelFilePath:C:\Temp\model.xml tooverride the model.xml in the .bacpac file. sqlpackage.exe /Action:Import /tsn:<server>.database.windows.net /tdn:<database> /tu:<user> /tp:<password> /sf:"C:\Temp\database.bacpac" /ModelFilePath:<path>model.xml When the import operation is completed, change the database name, or modify the application connection string to use the new database name. You can also check the new collation setting in the database properties using SSMS: Stop the maintenance window for your application and run the workload. Ensure that the application is working as expected.Export Azure SQL Database | Advanced Scenarios
Introduction: Export Azure SQL Database is a common request for Azure SQL DB customers, in this article we are going to list down some advanced scenarios, on how this can be achievable through various tools not limited to Azure Portal, Azure CLI and PowerShell. In addition, this article will provide alternative methods when it comes to private endpoints and deny public access. Scenarios: In this section, we are going through the scenarios and provide a thoughtful insight on each one. Note: - Import Export using Private Link now in public review, more information at blog article: Import Export using Private Link now in Preview - Microsoft Tech Community Export via Azure Portal to Storage Account This can be a seamless solution to do the database export when the SQL server allows the public access, untoggled the Deny public access option on SQL DB Azure portal, otherwise you might get error like: An unexpected error was returned by the SQL engine while preparing the operation inputs. Error: 47073, State: 1. To overcome such error, you canTEMPORARYset deny public access to NO during the export operation. Note: -You don’t need to worry, if you set “Deny public access” to “No” it doesn’t mean that everyone will be able to connect from outside; you still can restrict the access using the database firewall. You can find more information at: Connectivity settings for Azure SQL Database and Azure Synapse Analytics - Azure SQL Database and Azure Synapse Analytics | Microsoft Docs Export via REST API You can use Export REST API to export the database, this can be done programmatically, or from tools like Postman, Also you can try this from Azure Documentation using the >try it button, More information can be found at:Databases - Export - REST API (Azure SQL Database) | Microsoft Docs Here is an example using postman: Request Body: { "storageKeyType": "StorageAccessKey", "storageKey": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx= =", "storageUri": https://xxxxxxxxxxxxxxxxx.blob.core.windows.net/testc, "administratorLogin": "xxxxxxxxxxxx", "administratorLoginPassword": "xxxxxxxxxxxxxx", "authenticationType": "Sql", "networkIsolation": { "sqlServerResourceId": "/subscriptions/xxxxxxxxxxxxx/resourceGroups/customer/providers/Microsoft.Sql/servers/xxxxxxxxx", "storageAccountResourceId": "/subscriptions/xxxxxxxxxxx/resourceGroups/customer/providers/Microsoft.Storage/storageAccounts/xxxxxxxxx" } } Below error may occur if the Deny public access is enabled, the solution is to enable the public accesstemporarily {"error":{"code":"ResourceNotFound","message":"The specified resource 'https://management.northeurope.control.database.windows.net/modules/AzureResourceManager.dsts/subscriptions/<yoursubscriptionid>/resourceGroups/customer/providers/Microsoft.Sql/servers/<servername>/databases/<dbname>/export?api-version=2021-02-01-preview' was not found."}} Note:-networkisolation setting, this feature is currently under development and not ready for public consumption. More information can be found at: New-AzSqlDatabaseExport with network isolation · Discussion #13937 · Azure/azure-powershell · GitHub Error when calling New-AzSqlDatabaseExport with UseNetworkIsolation on $true · Issue #13964 · Azure/azure-powershell · GitHub Export via SQLPackage This can be a best bet solution for many scenarios to overcome limitations on the database size and also to export SQL DB via private endpoint through a VM running in the same VNET. Note:- you can export to local disk or Azure File Share, but you cannot use Azure Blob, for details can be found atLesson Learned #25: Export/Import Azure SQL Database using Azure File Service? - Microsoft Tech Community Therefore, you can export the .bacpac locally/File share on the VM in the same VNET as the private endpoint of the SQL Server using SQLPackage.exe/SSMS then copy the bacpac to Azure blob (if required). For example:Using SQLPackage to import or export SQL Server and Azure SQL DB - Microsoft Tech Community Export viaSQL server Management Studio :Export using SSMS from the VM running in the same VNET as a private endpoint from SQL to blob storage/ file share You can make use SQL Server Management Studio Export data-tier application wizard to export the Azure SQL database to a .bacpac file. The .bacpac can be stored into Azure blob storage or file share. Right click on the SQL Database on logical SQL Server from SSMS --> Tasks --> Select 'Export data-tier application' wizard. Select the location to store the BACPAC file You can select the subset of the tables from export setting in Advance tab --> Click Next to view the summary of export. One you click finish. And up on completion of the process you will be able to view the BACPAC file in the specified destination.

Make a note that you have to enable public access to export the database via this method.With Deny public access set to YES, you might encounter below error. PowerShell command to export the database.
