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.
Can Tables Be Created in The Datasheet View and The Design View?
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.

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.
Set the Field Properties for an Existing Table
If some value for a field is very common then you should consider setting a default value. For example, if most courses are 3-credit hour courses then the value 3 can be set as the default for all new courses. This data type restricts possible values to yes or no. If you choose AutoNumber MS Access will generate a value for you when a row is inserted into the table.

You may have noticed the little key icon next to the CustomerId field. A primary key is a unique identifier field for the table. No two records can contain the same value in their primary key field. This becomes crucial when establishing relationships between tables. You can use Design View to create a tables, set up data types for each field, specify default values, specify how data should be entered and displayed, and more.

We have just set a default value for the DateCreated field. This means that, whenever a new record is entered, this field will automatically be populated with the current date and time. We have also specified a format for all dates that are stored in this field. Design view enables you to design and set up your database (kind of a "behind the scenes" view of your database).
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.
Then, click the field updates from a bottom sheet with properties for a specific field. First of all, you have to click on Table Design option (from a Create tab).

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.
Modify the caption for these fields to be First Name and Last Name respectively. You will see these captions at the top of their respective columns. Consider the deptName field of the Department table. If a user enters data for a new department then it is unreasonable for the deptName field to not have a value. To ensure there will be a value we make the field required – i.e. we choose Yes for the Required property.
After that, choose a view that you wish from a drop-down list. Input masks are type of expression that allows you to specify exactly how data should be entered into a field. For example you could set it up so that users can only enter dates in a certain format, phone numbers in a certain format, etc. If MS Access rejects your primary key then you must examine the values you previously entered for deptCode – there must be some duplicated value.
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.
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.
The first time you do this, you will be prompted to provide a name for your table. Laurie Ulrich Fuller is a professional technology author and trainer. She's created training materials that cover Microsoft Office and Adobe Creative Suite.
