How to Link Tables in SQL Server 2008
When you’re using SQL Server 2008, one of the most common tasks that you’ll have to perform is linking tables. This process requires that you create a primary key, or URI, for each table in the database. Once you have this URI you can link these tables together. Linked tables always have up-to-date data because any changes made to one of them will automatically reflect in the other table.
VBA code can be used to link or relink tables. To link tables, you don’t need to use a specific version or edition of Access. You will need to set the Reference for the Microsoft DAO library (version 3.6 in Access 2000). As a result, you must ensure that the Linked Table source is installed on every machine where the VBA code will be used. Simply enter the URI in the text box, and then click OK.
Once the URI is added, you can use it in a query. To obtain different levels of information, you can use a system-stored procedure. When using a system stored procedure, you can select a specific set of parameters and pass them to the database. You can also use the openquery() method to make database queries. These are just a few examples of SQL Server 2008’s methods for linking tables.
If you’re using MS-Access, you can create linked servers using Visual FoxPro data sources. This way, your tables will have the same access to the SQL Server data. Another option is to add the ORIGINAL SQL Server database via a linked server. This is the best option for static data and read/write activity. Otherwise, you’ll need to refresh your data in SQL Server periodically. Once you’ve done this, you’ll be able to access the data on both servers.
Alternatively, you can create a relationship between two tables. A JOIN clause combines rows of two tables based upon a column that has a common attribute. If you have an “Orders”, and a “Customers”, the JOIN clause will return rows from both tables. A RIGHT OUTER JOIN, on the other hand, will return all rows from both left and right tables, even if one row is null.
Once you have your query results and result sets, you can join the two tables. The next step is to use an INSERT statement. You can download the AdventureWorks database sample for free if you are not familiar with SQL Server. This database includes sample results and is intended to help you understand the differences between the tables. If you have questions about joining tables in SQL Server 2008, you can view the AdventureWorks sample database on SQL Server to get a better grasp of the process.
