Answer 1

To get the versions history fields via SQL

• Open SQl Management Studio > Connect to your SharePoint server.
• Navigate to Content database like [WSS_Content].
• Create a new query from > right click Design Query in Editor > Select [dbo].[AllDocVersions] table inner join [AllDocs] table on Doc ID, select your required fields to show.

the Query should look like with your required fields

SELECT        AllDocVersions.Id, AllDocVersions.UIVersion, AllDocs.DirName, AllDocs.LeafName
FROM            AllDocs INNER JOIN
                         AllDocVersions ON AllDocs.Id = AllDocVersions.Id

Output:

Note:

Microsoft does not support any changes from the database , so it's heavily recommended to avoid any changes via the database.

[update]

Below is a PowerShell code which can be used to export version history to Excel Ref

# ******* Variables Section ******************
#Define these variables
$WebURL="http://sharepoint.crescent.com/sites/Sales/"
$ListName ="Invoice"
$ReportFile = "D:\Invoice_VersionHistory.csv"
# *********************************************

#delete file if exists
If (Test-Path $ReportFile)
 {
 Remove-Item $ReportFile
 }

#Get the Web and List
$Web = Get-SPWeb $WebURL
$List = $web.Lists.TryGetList($ListName)

 #Check if list exists
 if($List -ne $null)
 {
  #Get all list items
  $ItemsColl = $List.Items

  #Write Report Header
  Add-Content -Path $ReportFile -Value "Item ID, Version Lable, Created by, Created at, Title"

  #Loop through each item
  foreach ($item in $ItemsColl)
  {
   #Iterate each version
      foreach($version in $item.Versions)
       {
    #Get the version content
    $VersionData = "$($item.id), $($version.VersionLabel), $($version.CreatedBy.User.DisplayName), $($version.Created), $($version['Title'])"
    #Write to report
    Add-Content -Path $ReportFile -Value $VersionData
   }
  }
 }
Write-Host "Version history has been exported successfully!"
