Creating Tables

Now that we know how to read data from tables, we will now look at how to create new tables. There are fundamentally two ways to create tables: creating blank tables or using SELECT queries.

Creating Blank Tables

To create a new blank table, we use the CREATE TABLE statement. This statement takes the following structure:

CREATE TABLE {table_name} (
{column_name_1} {data_type_1} {column_constraint_1},
{column_name_2} {data_type_2} {column_constraint_2},
{column_name_3} {data_type_3} {column_constraint_3},
…
{column_name_last} {data_type_last} {column_constraint_last},
);

Here {table_name} is the name of the table, {column_name} is the name of the column, {data_type} is the data type of the column, and {column_constraint} is one or more optional keywords giving special properties to the column. Before we discuss how to use the CREATE TABLE query, we will first discuss column constraints.

Column constraints are keywords that...
