Important Points:

The general syntax of the INSERT statement is INSERT INTO table_name (column1, column2, …) VALUES (value1, value2, …);
We can use the PRIMARY KEY keyword to convert a column into a primary key;
The AUTO_INCREMENT keyword is used to make a column automatically assign incremented values to new rows. This can only be applied to columns that are INT or INT-based data types.

1. Which of the following are correct for creating a table with a primary key which auto increments?

2. What is the correct syntax for inserting new rows into an existing table?

Which of the following are correct for creating a table with a primary key which auto increments?

Select the correct answer

CREATE TABLE example (id PRIMARY KEY AUTO_INCREMENT);

CREATE TABLE example (id FLOAT PRIMARY KEY);

CREATE TABLE example (id INT PRIMARY KEY AUTO_INREMENT);

CREATE TABLE example (id INT AUTO_INCREMENT);

What is the correct syntax for inserting new rows into an existing table?

Select the correct answer

ADD ROW INTO TableName VALUES (value1, value2, ...);

INSERT INTO TableName (Column1, Column2, ...) VALUES (value1, value2, ...);

UPDATE TableName SET Column1 = value1, Column2 = value2, ...;

CREATE ROW IN TableName VALUES (value1, value2, ...);

Var allt tydligt?

Hur kan vi förbättra det?
