I am using C# Dapper with MYSQL.

I have a list of classes that i want to insert into MySQL table.

I used to do it using TVP in MS SQL, how do we do it in MySQL.

This project is not free but supports MySQL and offers all bulk operations:

• BulkInsert
• BulkUpdate
• BulkDelete
• BulkMerge

And some more options such as outputting identity values:

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

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