sp_MSdropconstraints is not available on Azure SQL Database

[aurelienhayet]

Hi,

When configuring Wolverine with the UseSqlServerPersistenceAndTransport and AutoProvision options, and then connecting to an Azure SQL Database, EXEC sp_MSdropconstraints commands are failing because of the unavailability of the sp_MSdropconstraints stored procedure.

Perhaps you can find alternative commands, or allow to opt-out the sp_MSdropconstraints commands ?

PS : Great great work by the way, congrats ;) !

Meh, that's in Weasel, not Wolverine. For the moment, you'll have to turn off AutoProvision and export the SQL through the command line. dotnet run -- db-dump [file path] and apply it manually. Might have to tweak the scripts to remove that call

Thanks Jeremy for your advice, that's what I did in order to unlock myself.
I apologize for the wrong location of the issue. I hesitated but as AutoProvision() was part of the wolverine project and was the root cause of this issue, I opted for it.
But you're right, it would be more relevant in Weasel.

Same happens with IMessageStore.Admin.MigrateAsync.

What am I doing wrong when I run 'dotnet run -- db-dump [path] -i`, when only an empty sql file is generated?

Code:

var builder = WebApplication.CreateBuilder(args);
builder.Host.ApplyOaktonExtensions();
builder.Host.UseWolverine((context, opts) => 
{
    var connectionString = context.Configuration.GetConnectionString("sqlserver")!;
    opts.UseSqlServerPersistenceAndTransport(connectionString, schema: "wolverine",
        transportSchema: "ppstransport");
    opts.AutoBuildMessageStorageOnStartup = false;
});
var app = builder.Build();
return await app.RunOaktonCommands(args);

For those who have the same problem: As a workaround, I created the stored procedure sp_MSdropconstraints via SQL Server Management Studio with the following code. After that, the app service starts without errors and the Wolverine tables are created.

Will be fixed by upgrading to the very latest Weasel after some work that @mysticmind just did. Does the polyfill just like @jnkb suggested -- and thanks for that tip!
