EntityFrameworkCore.MySql.SimpleBulks

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

Overview

This library provides extension methods so that you can use with your EntityFrameworkCore DbContext instance DbContextExtensions.cs or you can use MySqlConnectionExtensions.cs to work directly with a MySqlConnection instance without using EntityFrameworkCore.

Nuget

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

Features

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

Direct Delete

Examples

EntityFrameworkCore.MySql.SimpleBulks.Demo

Update the connection string:

private const string _connectionString = "server=localhost;database=SimpleBulks;user=root;password=mysql;AllowLoadLocalInfile=true";

Build and run.

Using Lambda Expression

using EntityFrameworkCore.MySql.SimpleBulks.BulkDelete;
using EntityFrameworkCore.MySql.SimpleBulks.BulkInsert;
using EntityFrameworkCore.MySql.SimpleBulks.BulkMerge;
using EntityFrameworkCore.MySql.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.MySql.SimpleBulks.BulkDelete;
using EntityFrameworkCore.MySql.SimpleBulks.BulkInsert;
using EntityFrameworkCore.MySql.SimpleBulks.BulkMerge;
using EntityFrameworkCore.MySql.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.GetMySqlConnection())
	.WithColumns(row => new { row.Column1, row.Column2, row.Column3 })
	// or .WithColumns([ "Column1", "Column2", "Column3" ])
	.WithOutputId(row => row.Id)
	// or .WithOutputId("Id")
	.ToTable(dbct.GetTableInfor(typeof(Row)))
	// or .ToTable("Rows")
	.Execute(rows);
