The SQL statement for the query is as follows: The designer window should look like this: Click OK to return to the Designer Window, and add the fields.Only those records from ‘Orders’ where the joined fields are equal.” In this case, we want option #2: “Include ALL records from ‘Customers’ and Notice that this shows the name of the Left table and the Right table, and lets you choose Double click on the line to open the Join properties.The Join line isĪutomatically added to join. In the Designer Window, add the Customers and the Orders tables.We can use a Left Outer Join to accomplish this.įollow these steps to design the query interactively (or paste the Query SQL instead): In this scenario, we want to see customers with orders AND customers without The following examples use the Customers and Orders tables from the Northwind 2007.accdb sample database to demonstrate these scenarios.Īssume that we want a list of all customers, and if they have any Orders, we want Troubleshooting Missing Data (Orphaned Rows).Finding Records that Exist in One Table, but Not in a Query (subset of another table).Finding Records in One table that Don't Exist in Another Table (the Not-In Query).Showing All Records from One Table with Fields from a Second Table If Linked Records Exist.There are several scenarios where Outer Joins should be used: These Joins can also be used to only retrieve the record values that exist in one table and not the other. RIGHT JOIN returns all records from the second table, even if there are no matching records in the first table. ![]() LEFT JOIN returns all records from the first table, even if there are no matching records in the second table.JOIN or the RIGHT JOIN syntax depending on which table is referenced first in the query: Simply use an Outer Join to generate "Not In" results. It turns out we can do this without any programming since it's part of the query SQL syntax. But what if we need to find records that exist in one table but not the other? Records with values that exist in both tables. When querying data from multiple tables in Microsoft Access or SQL Server, we usually use Inner Joins to link Microsoft Access Outer Join Query: Finding All Records in One Table but Not Another and Creating "Not In" Queries Provided by Molly Pell, Senior Systems Analyst
