NewLife.MySql.EntityFramework

NewLife.MySql — Pure C# High-Performance MySQL Driver

🌐 简体中文 | 繁體中文 | Español | Deutsch | 日本語 | Français | Português | Русский | 한국어 | العربية

NewLife.MySql is a pure C# MySQL client driver from the NewLife team. Built on the standard ADO.NET interfaces, it implements the MySQL protocol layer (Protocol Version 10) directly over TCP. It depends only on NewLife.Core, with zero third-party dependencies, true end-to-end async, and an MIT license for worry-free commercial use.

Its innovative Pipelined Batch Execution (Pipeline) delivers a 2×~3× speedup for batch writes in the tens-of-thousands-of-rows range (vs the row-by-row baseline), making it an ideal choice for big-data batch operations and domestic (信创) replacement scenarios.

Highlights

🚀 Pipelined Batch Execution (Pipeline)

An innovative pipelined mode based on the COM_STMT_PREPARE + COM_STMT_EXECUTE binary protocol:

• Phase 1: Build and send all EXECUTE packets in batch, flushing only the last packet
• Phase 2: Read all OK/Error responses in order in batch, accumulating the affected row count
• The TCP stack coalesces small packets (Nagle algorithm), so there is only one network round trip

Measured data (.NET 10 + MySQL 8.0.26 localhost, pipelining + transaction vs row-by-row baseline):

Scenario	Row-by-row baseline	Pipeline(tx)	Speedup
100-row INSERT	244ms	20ms	12.2×
1,000-row INSERT	2,473ms	70ms	35.3×
10,000-row INSERT	~70s¹	~0.7s¹	~98×

¹ The 10,000-row row-by-row figure without a transaction is extrapolated (2.4ms/row); the Pipeline figure is measured without a transaction. With a transaction, 10,000 rows take about 70ms.

Three-driver performance data (10,000-row batch operations):

Operation	NewLife Pipeline(tx)	MySql.Data Batch(tx)	MySqlConnector Batch(tx)
INSERT	899ms	1,927ms	1,906ms
UPDATE	710ms	2,265ms	2,041ms
DELETE	661ms	1,961ms	1,767ms

Thousands of rows already achieve a 35× speedup on a local LAN; the benefit is even greater across data centers. See the Performance Test Report for detailed data.

🔧 Six Batch Operation Options

Option	API	Use case
Dictionary parameter sets	ExecuteBatch	Dynamic parameters supplied by a collection
Value array binding	ExecuteBatchValues	Bulk import (MySqlBulkCopy internals), zero dictionary/parameter object allocations
Array binding	ExecuteArrayBatch	Large-volume DML, Oracle style
Pipelining	Pipeline=true	Tens of thousands / hundreds of thousands of rows, cross-data-center
Multi-row VALUES	Concatenated SQL	Pure INSERT batches
DbBatch (.NET 6+)	CreateBatch	Mixed batches of different SQL statements

🛡️ Zero Third-Party Dependencies

Depends only on NewLife.Core (also from the NewLife team), with no GPL licensing risk, an MIT license for worry-free commercial use, and suitability for 信创 environments and scenarios with strict security audits.

⚡ Extreme Performance Optimizations

• ArrayPool<T> + OwnerPacket for zero extra allocations
• Fully pooled Pool.StringBuilder / Pool.MemoryStream
• Full-chain async/await, with no sync-over-async anti-pattern
• Lean protocol parsing that reads only the necessary fields

🌐 Broad Compatibility

• Frameworks: net45 / net461 / netstandard2.0 / netstandard2.1 / net6.0 / net8.0 / net10.0
• NativeAOT: net8.0+ supports trimming and NativeAOT (IsAotCompatible, with an AotSmoke smoke test and a CI mainstream-RID matrix for regression protection; required win-x64 / linux-x64 / linux-arm64; LoongArch linux-la64 is covered by QEMU emulation (observation period: it runs, and failures do not block)), see AOT Compatibility Assessment
• MySQL: 5.5 ~ 9.0+, mysql_native_password + caching_sha2_password
• Compatible databases: OceanBase, TiDB, Doris (auto-detect), Aurora / CloudSQL (cloud databases), MariaDB (basic)
• Conditional compilation: automatically selects the optimal implementation per framework

---

Quick Start

Connection String

Server=localhost;Port=3306;Database=mydb;User Id=root;******;

Parameter	Aliases	Default	Description
Server	DataSource, Data Source	-	Server address
Port	-	3306	Port number
Database	-	-	Database name
UserID	Uid, User Id, User	-	Username
Password	Pass, Pwd	-	Password

Opening a Connection

using var conn = new MySqlConnection("Server=localhost;Database=mydb;User Id=root;******;");
conn.Open();
// The connection is closed automatically and returned to the pool when the using scope ends

Querying a Result Set

using var conn = new MySqlConnection(connStr);
conn.Open();

using var cmd = new MySqlCommand(conn, "SELECT id, name, age FROM users WHERE age > 18");
using var reader = cmd.ExecuteReader();

while (reader.Read())
{
    var id = reader.GetInt64(0);
    var name = reader.GetString(1);
    var age = reader.GetInt64(2);
    Console.WriteLine($"{id}: {name}, {age}");
}

Querying a Scalar

using var cmd = new MySqlCommand(conn, "SELECT COUNT(*) FROM users");
var count = cmd.ExecuteScalar();

Executing DML

using var cmd = new MySqlCommand(conn, "INSERT INTO users(name, age) VALUES('Tom', 25)");
var affectedRows = cmd.ExecuteNonQuery();

// Shortcut
var rows = conn.ExecuteNonQuery("DELETE FROM logs WHERE created < '2024-01-01'");

---

Parameterized Queries

Use the @parameter-name syntax to bind parameters; values are escaped automatically to prevent injection:

using var cmd = new MySqlCommand(conn, "SELECT * FROM users WHERE name = @name AND age > @age");
cmd.Parameters.AddWithValue("name", "Tom");
cmd.Parameters.AddWithValue("age", 18);

using var reader = cmd.ExecuteReader();
while (reader.Read())
{
    Console.WriteLine(reader.GetString(0));
}

// Parameterized insert
using var cmd = new MySqlCommand(conn, "INSERT INTO users(name, age, created) VALUES(@name, @age, @dt)");
cmd.Parameters.AddWithValue("name", "Alice");
cmd.Parameters.AddWithValue("age", 30);
cmd.Parameters.AddWithValue("dt", DateTime.Now);
cmd.ExecuteNonQuery();

// Passing NULL values
cmd.Parameters.AddWithValue("email", DBNull.Value);

Supported parameter types:

.NET Type	SQL Literal Example
String	'hello' (special characters escaped automatically)
Int32 / Int64 and other numeric types	42
Boolean	1 or 0
DateTime	'2025-07-01 12:30:00'
Byte[]	X'CAFE'
MySqlGeometry	WKB-format geometry data
Guid	'01234567-89ab-cdef-...'
Enum	Converted to a number
null / DBNull.Value	NULL

---

Transactions

using var conn = new MySqlConnection(connStr);
conn.Open();

using var tr = conn.BeginTransaction();
try
{
    conn.ExecuteNonQuery("INSERT INTO orders(product, qty) VALUES('Widget', 10)");
    conn.ExecuteNonQuery("UPDATE inventory SET qty = qty - 10 WHERE product = 'Widget'");
    tr.Commit();
}
catch
{
    tr.Rollback();
    throw;
}

Four isolation levels are supported: ReadUncommitted / ReadCommitted / RepeatableRead (default) / Serializable

using var tr = conn.BeginTransaction(IsolationLevel.ReadCommitted);

If a transaction is disposed without being committed or rolled back, it rolls back automatically.

---

Stored Procedures

using var cmd = new MySqlCommand { Connection = conn, CommandType = CommandType.StoredProcedure };
cmd.CommandText = "my_proc";
cmd.Parameters.AddWithValue("p_id", 1);

var outParam = new MySqlParameter { ParameterName = "p_result", Direction = ParameterDirection.Output };
cmd.Parameters.Add(outParam);

cmd.ExecuteNonQuery();
var result = outParam.Value; // Output parameter value

---

Prepared Statements

Use Prepare() to compile the SQL on the server; subsequent executions use the binary protocol:

using var cmd = new MySqlCommand(conn, "INSERT INTO users(name, age) VALUES(@name, @age)");
cmd.Parameters.AddWithValue("name", "Tom");
cmd.Parameters.AddWithValue("age", 25);

cmd.Prepare(); // Server-side prepare

cmd.ExecuteNonQuery(); // First execution

// Execute again after changing parameters (no recompilation needed)
cmd.Parameters[0].Value = "Jerry";
cmd.Parameters[1].Value = 30;
cmd.ExecuteNonQuery();

You can also enable it globally through the connection string, so that every parameterized query uses the binary protocol automatically:

UseServerPrepare=true;

---

Batch Operations

Option A: Dictionary Parameter Sets

Execute the same SQL with multiple sets of parameters bound; prepared internally and automatically:

using var cmd = new MySqlCommand(conn, "INSERT INTO users(name, age) VALUES(@name, @age)");
cmd.Parameters.AddWithValue("name", "");
cmd.Parameters.AddWithValue("age", 0);

var paramSets = new List<IDictionary<String, Object?>>
{
    new Dictionary<String, Object?> { ["name"] = "Alice", ["age"] = 25 },
    new Dictionary<String, Object?> { ["name"] = "Bob", ["age"] = 30 },
    new Dictionary<String, Object?> { ["name"] = "Charlie", ["age"] = 22 },
};
var totalAffected = cmd.ExecuteBatch(paramSets);
// or await cmd.ExecuteBatchAsync(paramSets);

Option B: Array Binding (Oracle style)

Set parameter values to arrays and specify the execution count:

using var cmd = new MySqlCommand(conn, "INSERT INTO users(name, age) VALUES(@name, @age)");
cmd.Parameters.AddWithValue("name", new[] { "Alice", "Bob", "Charlie" });
cmd.Parameters.AddWithValue("age", new[] { 25, 30, 22 });

var totalAffected = cmd.ExecuteArrayBatch(3);
// or await cmd.ExecuteArrayBatchAsync(3);

Option C: Pipelined Execution

Enable Pipeline=true in the connection string to send in batch and receive in batch with only one network round trip:

var connStr = "Server=localhost;Database=mydb;User Id=root;******;Pipeline=true;";
using var conn = new MySqlConnection(connStr);
conn.Open();

using var cmd = new MySqlCommand(conn, "UPDATE users SET age=@age WHERE name=@name");
cmd.Parameters.AddWithValue("age", agesArray);    // Int32[10000]
cmd.Parameters.AddWithValue("name", namesArray);   // String[10000]
var totalAffected = cmd.ExecuteArrayBatch(10000);

Pipelining works for INSERT / UPDATE / DELETE and can be combined with dictionary parameter sets or array binding. The higher the network latency (for example, across data centers), the greater the benefit.

Option D: Multi-row VALUES

var sql = "INSERT INTO users(name, age) VALUES('Alice', 25), ('Bob', 30), ('Charlie', 22)";
conn.ExecuteNonQuery(sql);

Option E: DbBatch API (.NET 6+)

var batch = conn.CreateBatch();
batch.BatchCommands.Add(new MySqlBatchCommand("INSERT INTO users(name, age) VALUES('X1', 10)"));
batch.BatchCommands.Add(new MySqlBatchCommand("INSERT INTO users(name, age) VALUES('X2', 20)"));
batch.BatchCommands.Add(new MySqlBatchCommand("UPDATE users SET age = age + 1 WHERE name = 'X1'"));

using var reader = batch.ExecuteReader();

EF Core Support

The NewLife.MySql.EntityFrameworkCore package provides an EF Core database provider supporting .NET 6 / .NET 8 / .NET 10.

dotnet add package NewLife.MySql.EntityFrameworkCore

public class AppDbContext : DbContext
{
    public DbSet<User> Users { get; set; } = null!;

    public AppDbContext(DbContextOptions<AppDbContext> options) : base(options) { }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<User>(entity =>
        {
            entity.ToTable("users");
            entity.HasKey(e => e.Id);
            entity.Property(e => e.Name).HasMaxLength(100).IsRequired();
        });
    }
}

var options = new DbContextOptionsBuilder<AppDbContext>()
    .UseMySql("Server=localhost;Database=mydb;User Id=root;******;")
    .Options;

using var context = new AppDbContext(options);

Supported features:

Feature	Description
Type mapping	Int / Long / String / DateTime / Decimal / Guid / Boolean / Byte[]
Query translation	LINQ → MySQL syntax (backticks, LIMIT/OFFSET)
Method translation	Contains / StartsWith / EndsWith / ToUpper / ToLower / Trim / Replace / Substring / Length
Member translation	DateTime.Year / Month / Day / Hour / Minute / Second
Migration support	CreateTable / AlterColumn / AddColumn / DropColumn / RenameTable / CreateIndex / DropIndex
Value generation strategy	AUTO_INCREMENT identity primary keys

---

SSL/TLS Encrypted Connections

// Encrypt if the server supports it, otherwise use plaintext
var connStr = "Server=localhost;Database=mydb;User Id=root;******;SslMode=Preferred;";

// Require encryption; throw if the server does not support it
var connStr2 = "Server=localhost;Database=mydb;User Id=root;******;SslMode=Required;";

SslMode	Behavior
None / Disabled	Do not use SSL (default)
Preferred	Prefer encryption, fall back to plaintext if unsupported
Required	Force encryption

---

Schema Information Queries

var databases = conn.GetSchema("Databases");  // Database list
var tables = conn.GetSchema("Tables");         // Table list
var columns = conn.GetSchema("Columns");       // Column information
var indexes = conn.GetSchema("Indexes");       // Index information

---

Async Methods

All core operations support asynchronous versions:

using var conn = new MySqlConnection(connStr);
await conn.OpenAsync();

using var cmd = new MySqlCommand(conn, "SELECT * FROM users");
using var reader = await cmd.ExecuteReaderAsync();

while (await reader.ReadAsync())
{
    Console.WriteLine(reader.GetString(0));
}

---

Tracing (OpenTelemetry)

The driver has built-in ActivitySource instrumentation (source name NewLife.MySql), emitting four kinds of spans: Open (connection), Execute (command, covering the reader lifetime), Commit / Rollback (transactions). Attributes follow the OpenTelemetry stable database semantic conventions (db.system.name / db.query.text / server.address / error.type, etc.). The OpenTelemetry SDK is supplied by the consumer; the driver adds no dependencies:

using var tracerProvider = Sdk.CreateTracerProviderBuilder()
    .AddSource("NewLife.MySql")
    .AddOtlpExporter()
    .Build();

• Scope: net6.0 and above; on lower versions and with no subscribers it is a zero-overhead no-op
• Privacy note: db.query.text records the command text; prefer parameterized queries so literals do not enter telemetry

---

Connection Pool

The connection pool is enabled by default with no extra configuration needed. Each unique connection string maps to its own independent pool.

• Connections are taken from the pool automatically when opened
• Connections are returned automatically when closed (the TCP connection is not dropped)
• Invalid connections are removed automatically
• New connections are created on demand
• Automatic reconnect after network disconnection: retries automatically when a dropped connection is detected, improving stability in long-lived scenarios

Connection Pool Parameters

Parameter	Default	Description
MinPoolSize	0	Minimum number of connections
MaxPoolSize	100	Maximum number of connections
ConnectionLifeTime	0	Connection lifetime (seconds); 0 means never expire
ConnectionIdleTime	300	Idle timeout (seconds); connections are reclaimed after it elapses
ValidationInterval	30	Idle validation interval (seconds)

var connStr = "Server=localhost;Database=mydb;...;MinPoolSize=5;MaxPoolSize=50;ConnectionLifeTime=3600;";

---

XCode ORM Integration

Auto-registered as the MySQL driver for XCode through MySqlClientFactory:

using XCode.DataAccessLayer;

DAL.AddConnStr("mysql", "Server=localhost;Database=mydb;User Id=root;******;", null, "MySql");

var dal = DAL.Create("mysql");
var tables = dal.Tables;

---

Switching Databases

ChangeDatabase (recommended)

using var conn = new MySqlConnection("Server=localhost;Database=db1;...");
conn.Open();
conn.ChangeDatabase("db2"); // Internally Close + Reopen

⚠️ Switching in the middle of a transaction is not supported (the transaction is lost); create an independent connection for each database.

SqlClient.SetDatabaseAsync (low-level API)

await conn.Client.SetDatabaseAsync("information_schema"); // COM_INIT_DB

Does not close the connection; only switches the server-side current database, suitable for temporary query scenarios.

---

OceanBase / TiDB Support

The driver detects the database type automatically from the version string in the handshake packet; the connection method is exactly the same as for MySQL:

// OceanBase
var connStr = "Server=oceanbase-host;Port=2881;Database=test;User Id=root;******;";
using var conn = new MySqlConnection(connStr);
conn.Open();
Console.WriteLine($"Database type: {conn.DatabaseType}");  // OceanBase

// TiDB
var connStr2 = "Server=tidb-host;Port=4000;Database=test;User Id=root;******;";
using var conn2 = new MySqlConnection(connStr2);
conn2.Open();
Console.WriteLine($"Database type: {conn2.DatabaseType}");  // TiDB

Basic SQL, transactions, parameterized queries, and batch operations are all compatible.

---

Target Frameworks

Framework	Description
net45 / net461	.NET Framework, compatible with legacy projects
netstandard2.0 / netstandard2.1	Cross-platform compatibility, supports async Dispose
net6.0	Additionally supports the DbBatch API
net10.0	Latest .NET, optimal performance

---

NativeAOT Deployment

With the net8.0+ target frameworks, the driver has passed real NativeAOT publish validation (local measurements and CI on win-x64 and linux-x64; all 26 smoke scenarios passed with 0 ILC warnings). Publishing native binaries requires no caller-side patches; CI continuously guards against regressions across a mainstream-RID matrix (win-x64 / linux-x64 / linux-arm64 / win-arm64 / osx-x64 / osx-arm64 / musl, plus a QEMU-emulated smoke test for LoongArch linux-la64 during the observation period, which is non-blocking):

<PropertyGroup>
  <PublishAot>true</PublishAot>
</PropertyGroup>

dotnet publish -c Release -r linux-x64

Item	Content
Scope	net8.0+; net6.0 requires an experimental switch, and earlier frameworks are not supported
Verified capabilities	Connection/authentication (including handshake connection attributes), sync and async queries, server-side prepare, batch (dictionary/array/value-array/pipelined), transactions, stored procedures, Schema metadata, DbDataSource, DataAdapter, MySqlBulkCopy, compression protocol, binlog subscription, tracing
Notes	The MySqlDataAdapter Fill/FillSchema/Update family carries RequiresUnreferencedCode annotations; trimmed applications declare the preservation responsibility at the call site per System.Data semantics
Detailed assessment	AOT Compatibility Assessment

---

Notes

1. MySQL version: 5.x and above supported, 8.0+ recommended
2. Character encoding: UTF-8 by default
3. ChangeDatabase: implemented via Close/Reopen; switching in the middle of a transaction is not supported, so use an independent connection
4. Pipelined execution: only for batch DML operations, not for SELECT queries
