Question

interpret the following SQL create table persons (person I'd int, last name varchar (255) first name varchar (255) address varchar (255) city varchar (255)​

Answer 1

Kindly check explanation

Step-by-step explanation:

The SQL statement above could be interpreted as follows :

create table command is used to create a table named 'persons' with five columns which are labeled :

person I'd : whose data type is an integer

last name column with a variable character data type with maximum length of 255

first name column with a variable character data type with maximum length of 255

address column with a variable character data type with maximum length of 255

city column with a variable character data type with maximum length of 255

The VARCHAR data type is ideal since we expect the column values to be of variable length.
