Dummies helps everyone be more knowledgeable and confident in applying what they know. In this section we will step through the process of creating a table. From the web page for these notes download and open the MyUniversity Database.
Microsoft Access Tutorial (Part : Design View, Field Properties, & Relationships
Suppose the University uses 3 and 4 character values for department codes. In this way we can limit the kinds of errors users make when they enter data and thus improve the overall quality of our database. Add a field, paperback, that can be used to indicate whether or not a book is a paperback. Now you will see how to enter such values – MS Access provides a box that is to be checked, or not. You can select (a ‘Yes’) using the mouse or by using the space bar. When users create an Access database, the data is stored in the table.

Also, you might find that you prefer to do certain tasks in Design View and other tasks in Datasheet View. Shantel has studied Data Operations, Records Management, and Computer Information Systems. Her goal is to become a Database Administrator or a System Administrator. Right-click the field that contains Address and selects Insert Rows.
Set the Field Properties for an Existing Table
Moreover, you can change each & every field’s properties. To create a column in the Design View, click an empty cell under Field Name and type the desired name. So now that we've established that Design View and Datasheet View are just two ways of looking at the same table, let's go ahead and create a table in Design View.
You might have noticed the little "key" icon to the left of the CustomerId field. A primary key ensures that the data in this column is unique - no two values can be the same. This is important for when you want to perform queries or run reports against the table, and it is vital for establishing relationships with other tables. Save the table and enter datasheet view so you can test out the datatype you have just created. You will notice the user sees a drop down list containing Male and Female, and so the user cannot enter/select an inappropriate value.

Validation rules and validation text are important features to assist database users. If a field will contain monetary values then the Currency data type should be chosen. This data type provides for numeric calculations that are accurate to 15 digits to the left of the decimal and 4 digits to the right of the decimal. You should still be in Design View for the Department table. Note that you can press the F1 function key to get help pertinent to the location of the mouse cursor. If your cursor is positioned on a Field Name and you press F1 you will see a window pop open that displays suggestions from MS Access regarding how you should name fields.
When individuals want to add Fields to their table, they usually add fields in the Design view. The Design View allows you to design and set up the database. The Design View is where you configure your table, forms, reports, etc. You can see that we have configured just two of many options in this pane.

Its attributes will be about thecharacteristics of the specific recordings in your collection. Well, there’re two views available while working with the tables in MS Access, one is the Design view & another is the Datasheet view. However, if you want to switch from Datasheet view to design view or vice-versa then click on a down arrow that you can see next to a View button on a toolbar.
You can, via the New Values property, arrange the numbers to be generated sequentially or randomly. Often control numbers for things like orders, invoices, registrations, etc. are numeric and we can leave it to the system to generate a next value for us. If a field is used for storing values that are used in numerical calculations (e.g. quantity ordered) then Number is appropriate. The Field Size property (properties are discussed later) can be used to limit the number of storage locations used per value. Creating a table in MS Access using a query is not an easy task as you think it is. To make it simpler, we have below discussed the complete steps for how to create table in MS Access using query.
Design View is a more flexible method for creating a new table, in which you directly enter information about each field in the table. We will use this method for the rest of the tables of our database. Strictly speaking, it is possible to have linked fields with non-matching data. You could allow this by disabling the Enforce Referential Integrity option on the Edit Relationships screen while setting up the relationship. So go ahead and create two more tables using the same steps you used to create the first table. Click the View icon to return to Datasheet view, and we'll look at the options for adding data to our table.
The Format property tells Access what format to store the data in. By using General Date, we tell Access to store this field in a general date format. When you click on a field, the field’s properties will be displayed in the bottom frame. You'll also see that the Ribbon now has a DESIGN tab with a new set of design-related options.
Ken Cook is a professional database developer, instructor, and author. The two experts have teamed to write the previous three editions of Access For Dummies. Get it right the first time and you’ll save yourself a lot of aggravation down the road.
If this happens you must view the table in Datasheet View and find the duplicated value and make necessary changes. To set a primary key the table must be open in Design View. You must first select the field (or combination of fields) and then click the Primary Key icon. This is straightforward for the Department table, but not for the Course table because its’ primary key comprises two fields. Because the PK involves more than one field we say this primary key is composite. Consider the firstName and lastName fields in the Member table of the Library database.
The Text data type provides for values that have fewer than 256 characters. You might remember that the fields with the little key icon are called primary keys (they are the unique identifier for the table). Well, the fields that link to those are called foreign keys. A Table is anentity (thing) that has attributes (fields) that fit together.
Though by following the simple steps mentioned below in this post, you can add a new table in design view in a hassle-free manner. If you specify that a field has the Text data type then Access will permit any characters to be placed in that field in a row of the table. This is a common choice when the data will not be used in calculations.
However, creating a table in Design View mode is an outdated method. So, if you want to create a table in this era, then it is suggested to create a table in Datasheet view. The Field properties will help you to specify the default value for each field, create the input mask and even stipulate whether it is an essential field, etc. Now, the properties shown in a bottom pane will be changed, it is completely depending on a file type of a selected field.
