将 azure sql 数据库还原到托管实例

Question

I am trying to do a daily restore from azure sql database (elastic pool) into a managed instance. I have tried to export and import the bacpac file but that failed with the following error:

TITLE: Microsoft SQL Server Management Studio

---

Could not import package.
Warning SQL72012: The object [XTP] exists in the target, but it will not be dropped even though you selected the 'Generate drop statements for objects that are in the target database but that are not in the source' check box.

Error SQL72014: .Net SqlClient Data Provider: Msg 102, Level 16, State 30, Line 1 Incorrect syntax near 'type'.
Error SQL72045: Script execution error. The executed script:

 CREATE USER [**************] WITH SID = 0x6B6F4FABE3FFA848BAFB6C956D9A7E9C, TYPE = E;

I have also tried to use the automation accounts to execute powershell but that also didn't seem to support the managed instance.

How can I restore these sql databases into the managed instance?

Answer 1

Congratulations you managed to get is work:

1. Create a copy of the DB
2. drop all AAD users from the database before exporting

This can be beneficial to other community members. Thank you.

Also what you can do is:

1. rename the .bacpac file to .zip and unzip it

2. go to model.xml file and find all entries that looks like:

    a) <Element Type="SqlRoleMembership"> b) <Element Type="SqlUser" Name=" c) <Element Type="SqlLogin" Name=" d) <Element Type="SqlExternalDataSource"

3. after that save the model.xml and run this powershell:

   $modelXmlPath = Read-Host "PAth to model.xml" $hasher =[System.Security.Cryptography.HashAlgorithm]::Create("System.Security.Cryptography.SHA256CryptoServiceProvider") $fileStream = new-object System.IO.FileStream ` -ArgumentList @($modelXmlPath, [System.IO.FileMode]::Open) $hash = $hasher.ComputeHash($fileStream) $hashString = "" Foreach ($b in $hash) { $hashString += $b.ToString("X2") } $fileStream.Close() $hashString

4. take the hash and substitute the actual checksum value at Origin.Xml

5. zip everything again and import anywhere (almost)
