The CREATE TABLE
command creates a new table in the database.
The following SQL creates a table called "Persons" that contains five columns: PersonID, LastName, FirstName, Address, and City:
CREATE TABLE Persons (
PersonID int,
LastName varchar(255),
FirstName varchar(255),
Address varchar(255),
City varchar(255)
);
The following SQL creates a new table called "TestTables" (which is a copy of two columns of the "Customers" table):
CREATE TABLE TestTable AS
SELECT customername, contactname
FROM customers;
