These are the steps to create a table in a SQL
Server 2014 database using SQL Server Management Studio (SSMS).
Ensuring you have the correct database expanded (in
our case, the TaskTracker database), right click on the Tables icon
and select Table... from the contextual menu:
A new table will open in Design view. While you
have this screen open, do the following:
Using the values in the screenshot, complete the
details in the Column Name column, the Data Type column,
and Allow Nulls column.
Make the TaskId column a Primary Key
field by right-clicking the button next to TaskId (i.e. the same area
where the key appears in the following screenshot) and selecting Set
Primary Key.
Make the TaskId column an identity
column by setting Is Identity to Yes (you can find
this option under theIdentity Specification section in the bottom pane).
Note that to set values in the bottom pane, you need to select the column name
in the top pane first. We're setting this column to be an auto-number column -
it will automatically generate a new number for each record that is created.
Set the Default Value of the DateCreated column
to (getdate()). (This will automatically insert the current date into that
field for each new record).
What we are doing is creating the column names,
specifying the type of data that can be entered into them, and setting default
values. Restricting the data type for each column is very important and helps
maintain data integrity. For example, it can prevent us from accidentally
entering a task name into a field for storing the current date. SQL Server will
prevent data from entering tables where the data doesn't adhere to the rules
that we've set for each column.
Save the table by selecting File > Save
Table_1 or by right-clicking on the Table's tab and selecting Save
Table_1 from the contextual menu:
When prompted, name your table (we'll call it Tasks):
Your New Table
Now that you've created a new table, it will appear
under your database in the Tables section. If you don't see it
immediately, try refreshing the Object Explorer. You can do this by right-clicking
on Tables and clicking Refresh from the contextual menu:
Here's a screenshot of the table with the Columns folder
expanded:
