OriginalWhat's Dapper Plus?
Like Dapper, Dapper Plus is a NuGet library where 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
// @nuget: Z.Dapper.Plus
using Z.Dapper.Plus;
// 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);

Dapper Plus - Mapper
Mapper
Dapper Plus Mapper allows to map the conceptual model (Entity) with the storage model (Database) and configure options to perform Bulk Actions.
// @nuget: Z.Dapper.Plus
using Z.Dapper.Plus;
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.
// @nuget: Z.Dapper.Plus
using Z.Dapper.Plus;
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.
// @nuget: Z.Dapper.Plus
using Z.Dapper.Plus;
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 modifies entities used for the next bulk action using a lambda expression.
// @nuget: Z.Dapper.Plus
using Z.Dapper.Plus;
connection.BulkInsert(orders)
.AlsoInsert(order => order.Items)
.ThenInsert(order => order.Invoice)
.ThenInsert(invoice => invoice.Items);
Include Actions
The Dapper Plus Include method allows resolving issues with multiple "ThenBulk[Action]" methods.
// @nuget: Z.Dapper.Plus
using Z.Dapper.Plus;
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
// @nuget: Z.Dapper.Plus
using Z.Dapper.Plus;
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));
