EntityFrameworkCore.SqlServer.SimpleBulks

This is a very simple .net core library that can help to work with large number of records 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.

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.

Using Dynamic String:

dbct.BulkInsert(rows, "Rows",
    new string[] { "Column1", "Column2", "Column3" });
dbct.BulkInsert(rows.Take(1000), "Rows",
    typeof(Row).GetDbColumnNames("Id"));
dbct.BulkInsert(compositeKeyRows, "CompositeKeyRows",
    new string[] { "Id1", "Id2", "Column1", "Column2", "Column3" });

dbct.BulkUpdate(rows, "Rows",
    "Id",
    new string[] { "Column3", "Column2" });
dbct.BulkUpdate(compositeKeyRows, "CompositeKeyRows",
    new string[] { "Id1", "Id2" },
    new string[] { "Column3", "Column2" });

dbct.BulkMerge(rows, "Rows",
    "Id",
    new string[] { "Column1", "Column2" },
    new string[] { "Column1", "Column2", "Column3" });
dbct.BulkMerge(compositeKeyRows, "CompositeKeyRows",
    new string[] { "Id1", "Id2" },
    new string[] { "Column1", "Column2", "Column3" },
    new string[] { "Id1", "Id2", "Column1", "Column2", "Column3" });

dbct.BulkDelete(rows, "Rows", "Id");
dbct.BulkDelete(compositeKeyRows, "CompositeKeyRows", new List<string> { "Id1", "Id2" });

Using Lambda Expression:

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

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