How Do I Access a Linked Server Database?

You can access a linked server database by using a SELECT statement in your primary database, referencing the linked server and the desired table.

Here's a basic example:

SELECT * 
FROM LinkedServerName.DatabaseName.SchemaName.TableName;

Explanation:

• LinkedServerName: This refers to the name you gave the linked server during its creation.
• DatabaseName: The name of the database on the linked server.
• SchemaName: The schema containing the table you want to access.
• TableName: The name of the table you want to query.

Practical Insights:

• You can also specify specific columns instead of using *.
• You can apply filters and joins within the SELECT statement to retrieve specific data.
• Ensure you have the necessary permissions to access the linked server and its databases.

Additional Methods:

• OpenQuery: This function provides a more structured way to access linked server data. You can use it to execute queries directly on the linked server.
• Linked Server Objects: You can directly access linked server tables and views using the OPENROWSET function.

Example Using OpenQuery:

SELECT * 
FROM OPENQUERY(LinkedServerName, 'SELECT * FROM DatabaseName.SchemaName.TableName');

Example Using Linked Server Objects:

SELECT * 
FROM OPENROWSET('LinkedServerName', 'DatabaseName.SchemaName.TableName');

Remember: Before using any of these methods, ensure the linked server is configured correctly and you have the necessary permissions.
