# SQL Server

SQL Server is a relational database management system developed by Microsoft. CAP has supported SQL Server as persistent.

## Configuration

To use SQL Server storage, you need to install the following extensions from NuGet:

    Install-Package DotNetCore.CAP.SqlServer

Next, add configuration items to the `ConfigureServices` method of `Startup.cs`.

    public void ConfigureServices(IServiceCollection services)
    {
        // ...

        services.AddCap(x =>
        {
            x.UsePostgreSql(opt=>{
                //SqlServerOptions
            });
            // x.UseXXX ...
        });
    }

#### SqlServerOptions

## Publish with transaction

### ADO.NET with transaction

    private readonly ICapPublisher _capBus;

    using (var connection = new SqlConnection("ConnectionString"))
    {
        using (var transaction = connection.BeginTransaction(_capBus, autoCommit: false))
        {
            //your business code
            connection.Execute("insert into test(name) values('test')",
                transaction: (IDbTransaction)transaction.DbTransaction);

            _capBus.Publish("sample.rabbitmq.mysql", DateTime.Now);

            transaction.Commit();
        }
    }

### EntityFramework with transaction

    private readonly ICapPublisher _capBus;

    using (var trans = dbContext.Database.BeginTransaction(_capBus, autoCommit: false))
    {
        dbContext.Persons.Add(new Person() { Name = "ef.transaction" });

        _capBus.Publish("sample.rabbitmq.mysql", DateTime.Now);

        dbContext.SaveChanges();
        trans.Commit();
    }
