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 without using EntityFrameworkCore.

Nuget

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

Features

Bulk Insert
Bulk Update
Bulk Delete
Bulk Merge
Bulk Match
Temp Table
Direct Insert
Direct Update
Direct Delete

Examples

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

dbct.BulkMerge(rows,
    "Id",
    [ "Column1", "Column2" ],
    [ "Column1", "Column2", "Column3" ]);
dbct.BulkMerge(compositeKeyRows,
    [ "Id1", "Id2" ],
    [ "Column1", "Column2", "Column3" ],
    [ "Id1", "Id2", "Column1", "Column2", "Column3" ]);

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

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