What's Dapper Plus?

Like Dapper,

Dapper Plus is a NuGet library that you can add to your project that will extend your IDbConnection and IDbTransaction interface with high efficient Bulk Actions Helpers (Insert, Update, Delete, and Merge).

It can be used with or without Dapper, and it's compatible with all other Dapper packages.

Example

// CONFIGURE & MAP entity
DapperPlusManager.Entity<Order>().Table("Orders").Identity(x => x.ID);

// CHAIN & SAVE entity
connection.BulkInsert(orders)
          .AlsoInsert(order => order.Items);
          .Include(order => order.ThenMerge(order => order.Invoice)
                                 .AlsoMerge(invoice => invoice.Items))
          .AlsoMerge(order => order.ShippingAddress);

Mapper

Dapper Plus Mapper allows to map the conceptual model (Entity) with the storage model (Database) and configure options to perform Bulk Actions.

DapperPlusManager.Entity<Order>().Table("Orders")
                                 .Identity(x => x.ID)
                                 .BatchSize(200);

Bulk Actions

Bulk Actions allow to perform a bulk insert, update, delete or merge and include related child items.

connection.BulkInsert(orders, order => order.Items)
          .BulkInsert(invoices, invoice => invoice.Items)
          .BulkMerge(shippingAddresses);

Also Bulk Actions

Also Bulk Actions allow to perform bulk action with a lambda expression using entities from the last Bulk[Action] or ThenBulk[Action] used.

connection.BulkInsert(orders)
          .AlsoInsert(order => order.Items)
          .AlsoInsert(order => order.Invoice)
          .AlsoInsert(order => order.Invoice.Items);

Then Bulk Actions

Then Bulk Actions is similar to Also Bulk Actions but modify entities used for the next bulk action using a lambda expression.

connection.BulkInsert(orders)
          .AlsoInsert(order => order.Items)
          .ThenInsert(order => order.Invoice)
          .ThenInsert(invoice => invoice.Items);

Include Actions

The Dapper Plus Include method allow resolving issues with multiple "ThenBulk[Action]" method.

connection.BulkInsert(orders)
          .Include(x => x.ThenInsert(order => order.Items)
                         .ThenInsert(orderItem => orderItem.Metas))
          .Include(x => x.ThenInsert(order => order.Invoice)
                         .ThenInsert(Invoice => invoice.Items));   	

Transaction

All Dapper Plus extension methods are also available on the IDbTransaction interface

transaction.BulkInsert(orders)
          .Include(x => x.ThenInsert(order => order.Items)
                         .ThenInsert(orderItem => orderItem.Metas))
          .Include(x => x.ThenInsert(order => order.Invoice)
                         .ThenInsert(Invoice => invoice.Items));
