Step-by-Step Guide

To create the query across multiple tables, follow these steps:

Step 1: Open the Query Wizard

Start Access and go to the database that contains the relevant tables. Click "Create" in the top menu, and then select "Query Wizard". This is the starting point for creating your query.

Step 2: Select the Query Type

A dialog box will appear asking you what type of query you want to create. Select "Select Query" as you will need specific data. The Select Query allows you to easily filter data.

Step 3: Choose the Relevant Tables

Now you can select the tables that are important for your query. You have a customer table, a driver table, and a trip table. Add all relevant tables to effectively link the data.

Step 4: Select Fields from the Customer Table

Start by selecting from the customer table. You will likely want to display the first name and last name of the customers. Select these fields and add them to the selection. This allows you to see the customer information in the query.

Step 5: Add Functions from the Trip Table

Switch to the trip table to display information about the trips. Here you can select the trip number, price, start and destination address, and other relevant fields. By adding this information, you can clarify the connection between customers and trips.

Step 6: Add Driver Information

Now switch to the driver table to integrate data about the drivers. Select the driver's first name. If you want, you can also add the driver's photo. This provides you with visual support.

Step 7: Select Car Information

Don't forget to also add information about the car. Important details such as the number of seats, the license plate, and whether it is a premium ride are relevant. This information helps increase the clarity of the query.

Step 8: Compile the Query

Once you have added all the desired fields, click "Next". Here you have the option to decide whether you want to display the details of each field or create a summary. Choose the desired option and click "Finish".

Step 9: Adjust the Data View

Now the query is displayed, containing all the fields you selected. You get an overview of the customers, their trips, the drivers, and all corresponding information in one place.

Step 10: Refine the Data in Design View

You have the option to switch to design view to further customize your query. Here you can add more fields, hide specific fields, or sort by relevant criteria, such as by trip number.
