You’ll notice that this output in the total_time column is rather long and difficult to read.
This data type combines both date and time in one string, and its format is a combination of those of DATE and TIME: ( YYYY-MM-DD HH:MM:SS).Ĭreate the table by running the CREATE TABLE command: end_time: uses the TIMESTAMP data type to track the runners’ times at the end of the race.In this case, decimal specifies a precision of three with a scale of one, meaning that any values in this column can have three digits, with one of those digits being to the right of the decimal point. total_miles: shows the total mileage for each race using the decimal data type since many of the total miles per race are not whole numbers.This data type follows a 24-hour clock format, such as 15:00 for the equivalent of 3:00 pm. start_time: represents the race start time with the TIME data type by hours, minutes, and seconds ( HH:MM:SS).This data type adheres to the following parameters: four digits for the year, and a maximum of two digits for the month and day ( YYYY-MM-DD). start_day: uses the DATE data type to track the date of a specific race by year, month, and day.race_name: holds the types of races with the varchar data type at a maximum of 20 characters.runner_name: uses the varchar data type with a maximum of 30 characters for the names of the two racers, Bolt and Felix.race_id: displays values of the int data type and serves as the table’s primary key, meaning each value in this column will function as a unique identifier for its respective row.This table will hold the following seven columns: For this tutorial’s example, we’ll create a table that holds two runners’ results for various races they’ve run in the span of a year. If the database was created successfully, you’ll receive the following output:Īfter selecting the database, create a table within it. Next, open the MySQL prompt, replacing sammy with your MySQL user account information: If your SQL database runs on a remote server, SSH into your server from your local machine: Connecting to MySQL and Setting up a Sample Database This tutorial will refer to this sample database and table throughout.

If you do not have one ready to insert, you can read the following Connecting to MySQL and Setting up a Sample Database section to learn how to create a database and table. To practice using date and time in this tutorial, you’ll need a database and table loaded with sample data. Although the commands outlined in this tutorial will work on most RDBMSs, the exact syntax or output may differ if you test them on a system other than MySQL. Note: Please note that many relational database management systems use their own unique implementations of SQL. This guide assumes you’ve also set up a non-root MySQL user, as outlined in Step 3 of this guide.

Follow our How To Install MySQL on Ubuntu 20.04 guide to set this up. MySQL installed and secured on the server.Follow our Initial Server Setup with Ubuntu 20.04 to get started. A server running Ubuntu 20.04, with a non- root user with sudo administrative privileges and firewall enabled.To complete this tutorial, you will need: Then you’ll practice by running queries on sample data, and you’ll learn how to implement the CAST function to make the output more digestible to read. You’ll begin by performing arithmetic and using various functions with dates and times using only the SELECT statement. In this tutorial, you will learn how to use dates and times in SQL. For instance, you may need to calculate the total hours spent on a certain activity, or perhaps you need to manipulate date or time values using mathematical operators and aggregate functions to calculate their sum or average. When working with relational databases and Structured Query Language (SQL), there may be times when you need to work with values representing specific dates or times.
