So, you may ask, "What is wrong with this query? Well, it all comes down to what I mentioned earlier: Access will load the entire data set prior to filtering the data and returning the results. Now if you run the query as-is (via either selecting Query | Run from the menu bar or by clicking on the button the following results are displayed. The Access Query Designer should look something like this: Select to sort the results by 'Company Name' and to limit the results to only those where the Ship Country is 'USA'. The Access Query Designer is very similar to the one you find incorporated into SQL Server.ĭouble-click the fields as follows in order to load them into the query:
I have altered the tables' graphical placement and size for presentation purposes, but your screen should be similar. What you will see next is a query screen that looks something like what is presented below. Next, click the 'Add' button to begin designing the query. Once the 'Show Table' interface displays, then select the three tables: dbo_Orders, dbo_Customers, and dbo_Employees. Select the 'Create query in Design view' option on the right pane of the window. You should see a form similar to what is displayed below. Select 'Queries' under the 'Objects' menu on the left side of the main Access interface. Let's take a minute to create a basic Access query against the dbo_Orders, dbo_Customers, and dbo_Employees tables first. The 'Tables' listing should look something like what you see below.

When querying a linked table, Access will return/load the entire table into Access before parsing the WHERE or HAVING clauses. At this point you can use the linked tables as you would any other native Access table.

Thus far in this tips series on Access and SQL Server we have created an ODBC Data Source Name (DSN) using the OLEDB driver, created a System DSN for the new SNAC (SQL Native Client) driver and created linked tables in Access by using the SNAC DSN.
