SQL-Server和MySQL的互操作性? [英] SQL-Server and MySQL interoperability?

问题描述

我们正在从SQL-Server 2008后端过渡到MySQL后端. SQL-Server和MySQL之间的互操作性是什么?

We're going from a SQL-Server 2008 backend to a MySQL backend. What's the interoperability between SQL-Server and MySQL?

我们将能够运行引用服务器中数据库中的表的SQL查询吗?

Will we be able to run SQL Queries that reference tables from databases across the servers?

例如，是否可能这样:伪代码

For example, is this possible: pseudo code

SELECT * 
FROM 
      [SQL2008Server].[databaseA].[DBO].[table1] as t1 
  INNER JOIN 
      [MySQLServer].[databaseB].[dbo].[table2] as t2 
          ON t1.id = t2.fkid

如果没有，您可以推荐哪些选项来跨SQL Server 2008和MySQL集成数据?

If not, what options can you recommend for integrating data across SQL-Server 2008 and MySQL?

LINQ在合并来自SQL Server和MySQL的数据方面是否可以提供任何帮助?

Would LINQ provide any relief in regards to combining data from SQL-Server and MySQL?

推荐答案

可以将MySQL服务器作为链接服务器添加到SQL Server中.

It is possible to add a MySQL server into SQL Server as a linked server.

• HOWTO:设置SQL Server将服务器链接到MySQL

设置完成后，您可以使用OPENQUERY进行查询，如下所示:

Once you have set it up you can query using OPENQUERY like this:

SELECT t1.colA, t2.colB
FROM SQLdbName.dbo.tablename AS t1
INNER JOIN OPENQUERY(MySQLlinkedservername, 
                     'SELECT colA, colB FROM tablename') AS t2
ON t1.colA = t2.colA
