create table in sql

The SQL syntax for CREATE TABLE is

CREATE TABLE "table_name"
("column 1" "data_type_for_column_1",
"column 2" "data_type_for_column_2",
... )

So, if we are to create the customer table specified as above, we would type in

CREATE TABLE customer
(First_Name char(50),
Last_Name char(50),
Address char(50),
City char(50),
Country char(25),
Birth_Date date)

Sometimes, we want to provide a default value for each column. A default value is used when you do not specify a column's value when inserting data into the table. To specify a default value, add "Default [value]" after the data type declaration. In the above example, if we want to default column "Address" to "Unknown" and City to "Mumbai", we would type in

CREATE TABLE customer
(First_Name char(50),
Last_Name char(50),
Address char(50) default 'Unknown',
City char(50) default 'Mumbai',
Country char(25),
Birth_Date date)
