Dive into MySQL, a powerful database system for developers handling complex data structures. Learning MySQL equips you with skills for diverse applications, from web development to advanced data analysis, enhancing your ability to manage and manipulate data efficiently.

This course starts with MySQL Shell basics, leading to exploring data types and mastery of SQL statements. You will learn about user-defined variables and table expressions and delve into JSON and XML data handling. The course also covers spatial data management and advanced techniques like recursive queries and window functions. Each module builds upon the last, ensuring a comprehensive understanding of MySQL’s capabilities.

After completing this course, you will have a solid grasp of MySQL and be ready to solve intricate data problems. This expertise opens doors to advanced database roles and opportunities, elevating your career in the tech industry.

Mastering Advanced SQL Techniques with MySQL

**(Select all that apply.)** What are valid literal syntax formats to specify a `DATE`?

(Select all that apply.) What are valid literal syntax formats to specify a <code>DATE</code>?

Besides the time of the day, `TIME` can also represent elapsed time, which can span more than the hours of the day.

The first of the three digits is necessary to represent the sign of the hours.

This is a design specification of MySQL that lacks further reasoning.

Through this, `TIME` supports precise calculations down to milliseconds.

Why does `TIME` allow to specify three digits for the hour part, i.e., `hhh`?

Why does <code>TIME</code> allow to specify three digits for the hour part, i.e., <code>hhh</code>?

**(Select all that apply.)** What characters can the date and time in `DATETIME` be separated with?

(Select all that apply.) What characters can the date and time in <code>DATETIME</code> be separated with?

There is no remarkable difference between the two data types. They're just two ways to represent the same type of value.

While both represent dates associated with a time, `TIMESTAMP` restricts the time to the hours of the day, the date to years between 1970 and 2038, and associates the stored value with time zone information.

`DATETIME` represents a date associated with a time, while `TIMESTAMP` just stores a time.

`DATETIME` stores time up to milliseconds, while `TIMESTAMP` stores time up to nanoseconds.

What is the remarkable difference between `DATETIME` and `TIMESTAMP`?

What is the remarkable difference between <code>DATETIME</code> and <code>TIMESTAMP</code>?

`YEAR-01-01` where `YEAR` is the value to be converted to a `DATE`.

A syntax error since `YEAR` does not contain the information necessary to create a corresponding value of type `DATE`.

`YEAR-12-31` where `YEAR` is the value to be converted to a `DATE`.

What value will a conversion from `YEAR` to `DATE` result in?

What value will a conversion from <code>YEAR</code> to <code>DATE</code> result in?

Not at all, it’s not possible in MySQL.

Using the `CAST` operator with the target data type `YEAR`.

Using the `CAST` operator with the target data type `DATETIME`.

To extract the year from a `DATETIME` value, use the function `GET_YEAR()`.

How can you extract the year from a value of type `DATETIME`?

How can you extract the year from a value of type <code>DATETIME</code>?

The `CAST` operator does not permit `TIMESTAMP` as a target data type.

`DATE` does not contain information about the time necessary to create a value of type `TIMESTAMP`.

A value of type `TIMESTAMP` cannot hold the information about the date from `DATE`.

Why does attempting to convert a value of type `DATE` to a value of type `TIMESTAMP` using the `CAST` operator result in a syntax error in MySQL?

Why does attempting to convert a value of type <code>DATE</code> to a value of type <code>TIMESTAMP</code> using the <code>CAST</code> operator result in a syntax error in MySQL?
