Testdome Interview question - Mysql Stored Procedure

 Mysql Stored Procedure 
A company needs a stored procedure that will insert a new user with an appropriate type.

Consider the following tables:

TABLE userTypes
id INTEGER NOT NULL PRIMARY KEY, type VARCHAR(50) NOT  NULL
TABLE users
id INTEGER NOT NULL  PRIMARY KEY  AUTO_INCREMENT, email VARCHAR(50)NOT NULL, userTypeId INTEGER NOT NULL ,FOREIGN KEY(userTypeId) REFERENCES  user Types (id)
Finish the insertUser procedure so that it inserts a user, with these requirements:
• id is auto incremented.
• email is equal to the email parameter.
• userTypeld is the id of the userTypes row whose type attribute is equal to the type parameter.
DELIMITER $$
CREATE PROCEDURE insertUser(
    IN p_email VARCHAR(50),
    IN p_type VARCHAR(50)
)
BEGIN
    DECLARE v_userTypeId INT;
    -- Get userTypeId from userTypes table
    SELECT id INTO v_userTypeId  FROM userTypes WHERE type = p_type    LIMIT 1;
    -- Insert into users table
    INSERT INTO users (email, userTypeId)  VALUES (p_email, v_userTypeId);
END $$

Instead of scattering our component logic across various options like data, methods, computed, and watch, the Composition API encourages us to organize our logic into smaller, reusable functions called composition functions. One of the primary features of the Composition API is the setup() function. This function replaces the traditional options like data, methods, and others. Inside the setup() function, we can define reactive state using ref() and reactive() functions, set up lifecycle hooks using functions like onMounted(), and create computed properties and watchers using computed() and watch() functions. One significant benefit of the Composition API is better organization and reusability of code. By breaking our component logic into smaller funct...
