SQL doesn’t just select data; you can also use it to create tables and link them together with relationships. This blog shows you how!

- Creating a Table Programmatically in SQL
- Linking Tables (Foreign Keys and Relationships)
This blog is part of a much longer tutorial on programming in SQL. Alternatively, have a look at our classroom-based training courses in SQL.

Creating Databases using SQL
Tables that you create have to belong in a database, and you can create one of these in SQL. The command is:
So if you were creating a database to hold books and authors, you might run:
-- create a new database
CREATE DATABASE Literature
As always with SQL, you have to be careful to refresh your server in order to be able to see your new database:
|
|
| Right-click on Databases ... | ... to show your new one. |
You can also delete any existing database before creating a new one, to make sure you start with a clean slate:
-- try to delete the database
BEGIN TRY
DROP DATABASE Literature
END TRY
BEGIN CATCH
END CATCH
-- now create a new database
CREATE DATABASE Literature
Now that we've got a database, it's time to create a new table in it!
