EntityFrameworkCore.SqlServer.SimpleBulks

A very simple .net core library that can help to sync a large number of records in-memory into the database using the SqlBulkCopy class.  

Overview

This library provides extension methods so that you can use with your EntityFrameworkCore DbContext instance: DbContextExtensions.cs or you can use SqlConnectionExtensions.cs to work directly with a SqlConnection instance.

Nuget

https://www.nuget.org/packages/EntityFrameworkCore.SqlServer.SimpleBulks

EntityFrameworkCore.SqlServer.SimpleBulks supports:

• Bulk Insert
• Bulk Update
• Bulk Delete
• Bulk Merge

Examples

• Refer EntityFrameworkCore.SqlServer.SimpleBulks.Demo

• Update the connection string:

  private const string _connectionString = "Server=.;Database=SimpleBulks;User Id=xxx;Password=xxx";

• Build and run.

DbContextExtensions:

Using Lambda Expression:

using EntityFrameworkCore.SqlServer.SimpleBulks.BulkDelete;
using EntityFrameworkCore.SqlServer.SimpleBulks.BulkInsert;
using EntityFrameworkCore.SqlServer.SimpleBulks.BulkMerge;
using EntityFrameworkCore.SqlServer.SimpleBulks.BulkUpdate;

// Insert all columns
dbct.BulkInsert(rows);
dbct.BulkInsert(compositeKeyRows);

// Insert selected columns only
dbct.BulkInsert(rows,
    row => new { row.Column1, row.Column2, row.Column3 });
dbct.BulkInsert(compositeKeyRows,
    row => new { row.Id1, row.Id2, row.Column1, row.Column2, row.Column3 });

dbct.BulkUpdate(rows,
    row => new { row.Column3, row.Column2 });
dbct.BulkUpdate(compositeKeyRows,
    row => new { row.Column3, row.Column2 });

dbct.BulkMerge(rows,
    row => row.Id,
    row => new { row.Column1, row.Column2 },
    row => new { row.Column1, row.Column2, row.Column3 },
    options =>
    {
        //options.WithHoldLock = true;
    });
dbct.BulkMerge(compositeKeyRows,
    row => new { row.Id1, row.Id2 },
    row => new { row.Column1, row.Column2, row.Column3 },
    row => new { row.Id1, row.Id2, row.Column1, row.Column2, row.Column3 },
    options =>
    {
        //options.WithHoldLock = true;
    });
                        
dbct.BulkDelete(rows);
dbct.BulkDelete(compositeKeyRows);

Using Dynamic String:

using EntityFrameworkCore.SqlServer.SimpleBulks.BulkDelete;
using EntityFrameworkCore.SqlServer.SimpleBulks.BulkInsert;
using EntityFrameworkCore.SqlServer.SimpleBulks.BulkMerge;
using EntityFrameworkCore.SqlServer.SimpleBulks.BulkUpdate;

dbct.BulkUpdate(rows,
    new [] { "Column3", "Column2" });
dbct.BulkUpdate(compositeKeyRows,
    new [] { "Column3", "Column2" });

dbct.BulkMerge(rows,
    "Id",
    new [] { "Column1", "Column2" },
    new [] { "Column1", "Column2", "Column3" },
    options =>
    {
        //options.WithHoldLock = true;
    });
dbct.BulkMerge(compositeKeyRows,
    new [] { "Id1", "Id2" },
    new [] { "Column1", "Column2", "Column3" },
    new [] { "Id1", "Id2", "Column1", "Column2", "Column3" },
    options =>
    {
        //options.WithHoldLock = true;
    });

Using Builder Approach in case you need to mix both Dynamic & Lambda Expression:

new BulkInsertBuilder<Row>(dbct.GetSqlConnection())
	.WithData(rows)
	.WithColumns(row => new { row.Column1, row.Column2, row.Column3 })
	// or .WithColumns(new [] { "Column1", "Column2", "Column3" })
	.WithOuputId(row => row.Id)
	// or .WithOuputId("Id")
	.ToTable(dbct.GetTableName(typeof(Row)))
	// or .ToTable("Rows")
	.Execute();

SqlConnectionExtensions:

Using Lambda Expression:

using EntityFrameworkCore.SqlServer.SimpleBulks.BulkDelete;
using EntityFrameworkCore.SqlServer.SimpleBulks.BulkInsert;
using EntityFrameworkCore.SqlServer.SimpleBulks.BulkMerge;
using EntityFrameworkCore.SqlServer.SimpleBulks.BulkUpdate;

// Register Type - Table Name globaly
TableMapper.Register(typeof(Row), "Rows");
TableMapper.Register(typeof(CompositeKeyRow), "CompositeKeyRows");

connection.BulkInsert(rows,
           row => new { row.Column1, row.Column2, row.Column3 });
connection.BulkInsert(compositeKeyRows,
           row => new { row.Id1, row.Id2, row.Column1, row.Column2, row.Column3 });

connection.BulkUpdate(rows,
           row => row.Id,
           row => new { row.Column3, row.Column2 });
connection.BulkUpdate(compositeKeyRows,
           row => new { row.Id1, row.Id2 },
           row => new { row.Column3, row.Column2 });

           row => row.Id,
           row => new { row.Column1, row.Column2 },
           row => new { row.Column1, row.Column2, row.Column3 },
           options =>
           {
               //options.WithHoldLock = true;
           });
