Is there a way to stop SQL Release dropping tables? Or do we have to create a manual review step to check this?

    SQL Release will always drop tables if they aren't being source controlled. But you do have some ways to stop it.

    The simplest way is to add a filter that ignores the tables that are being dropped (https://documentation.red-gate.com/disp ... QL+Release), this works if the tables that are being dropped are always the same ones.
    Alternatively you can check all tables into Source Control.

    You can add a manual review step or interrogate the warnings with powershell and stop if there is a table drop:
    $ErrorActionPreference = "Stop"
    $db = New-DlmDatabaseConnection -ServerInstance .sql2012 -Database northwind
    $scripts = "C:Northwind"
    $release = New-DlmDatabaseRelease -Source $scripts -Target $db
    if ($release.Warnings.Details -match "The table S* is being dropped") {
        throw "Table being dropped"

    If you mean you want to rename instead of Drop/create you can use Migrations for this https://documentation.red-gate.com/disp ... on+scripts
