Master Database Skills: How to Merge Two Queries in Access?

In Microsoft Access, queries are important components that allow users to retrieve specific data by filtering & sorting records based on defined criteria. But sometimes, users need to merge two queries in the database to create complete reports or analyze data more efficiently. Well, this blog covers the step-by-step process of how to merge two queries in Access.

So, let’s get started…

Things To Be Considered Before Merging Two Queries in Access

Before performing any tasks whether it is running queries, merging tables/queries, or any other, it is important to know what you need to do or what not to do. The same applies to the query merging process.

Here, are some of the important things that you should remember before you combine two queries in Access:

1. Avoid Duplicates Records- In the Access database, if you don’t want duplicate records, then you must use the “UNION” option instead of “UNION ALL”.
2. Confirm Field Compatibility- It is vital to ensure that the fields you are merging have the same data types. As incompatibility in the data type can lead to errors or issues.
3. Check Twice Before Finalizing- Check the merged query twice to confirm that the data is accurate & complete.

Now, let’s scroll down this webpage to learn how to combine two queries in Access in easy steps.

How to Merge Two Queries in Access?

It seems very difficult to join two queries in Access without having proper knowledge regarding the database. But in this section, we will guide you on how to merge two queries in Access with ease and a hassle-free manner by using the UNION Query feature.

So, let’s see how to use the union query feature to accomplish this task:

• First of all, create a new query that owns the left outer join on a field that you need to use for the full outer join.
• Then, navigate to a Home tab, under the Views category.
• Now, click on the View >> SQL View.

• After that, press the CTRL+C keys together to copy an SQL code.
• Next, remove the semicolon from an end of a FROM clause >> hit ENTER.
• Enter the UNION, and press ENTER key.

• After this, press the CTRL+V keys simultaneously to paste a copied SQL code.
• Under the pasted code, change the LEFT JOIN to RIGHT JOIN.
• Now, remove the semicolon from the end of a FROM clause >> hit ENTER.
• At this time, add the WHERE clause that stipulates that a value of a join field is (NULL) in the first table itemized in the FROM clause (the left table).

As, if the FROM clause is:

FROM Products RIGHT JOIN [Order Details] ON Products.ID = [Order Details].[Product ID]

Then you would add the below WHERE clause:

WHERE Products.ID IS NULL

• Now, type the semicolon (;) in the end of a WHERE clause to specify the end of a union query.
• Go to a Design tab, under a Results group, you have to click Run option.

This will combine two queries in one.
