在 SQL Server 中,分庫分表通常通過以下步驟實現:
CREATE DATABASE db1;
CREATE DATABASE db2;
USE db1;
CREATE TABLE table1 (
id INT PRIMARY KEY,
name VARCHAR(50)
);
USE db2;
CREATE TABLE table2 (
id INT PRIMARY KEY,
description TEXT
);
CREATE PARTITION FUNCTION MyPartitionFunction (INT)
AS RANGE LEFT FOR VALUES (100, 200, 300);
CREATE PARTITION SCHEME MyPartitionScheme
AS PARTITION MyPartitionFunction
TO (db1, db2, db1, db2);
CREATE EXTERNAL DATA SOURCE RemoteDataSource
WITH (
TYPE = RDBMS,
LOCATION = 'remote.server.com',
DATABASE_NAME = 'remote_db'
);
CREATE EXTERNAL TABLE [dbo].[table1]
(
id INT,
name VARCHAR(50)
)
WITH
(
DATA_SOURCE = RemoteDataSource
);
以上是一些常見的方法來實現 SQL Server 的分庫分表,可以根據具體的需求和數據規模選擇合適的方式來進行數據分隔和管理。
