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.
Nuget
https://www.nuget.org/packages/EntityFrameworkCore.SqlServer.SimpleBulks
EntityFrameworkCore.SqlServer.SimpleBulks supports:
- Bulk Insert
- Bulk Update
- Bulk Delete
- Bulk Merge
Examples
-
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,
new [] { "Column3", "Column2" });
dbct.BulkUpdate(compositeKeyRows,
new [] { "Column3", "Column2" });
dbct.BulkMerge(rows,
"Id",
new [] { "Column1", "Column2" },
new [] { "Column1", "Column2", "Column3" });
dbct.BulkMerge(compositeKeyRows,
new [] { "Id1", "Id2" },
new [] { "Column1", "Column2", "Column3" },
new [] { "Id1", "Id2", "Column1", "Column2", "Column3" });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,

using EntityFrameworkCore.SqlServer.SimpleBulks.BulkUpdate;

connection.BulkDelete(rows, "Rows", "Id");
connection.BulkDelete(compositeKeyRows, "CompositeKeyRows", new [] { "Id1", "Id2" });Using Builder Approach in case you need to mix both Dynamic & Lambda Expression:
