In this guide, we’ll go over everything you need to know to get started with MySQL Workbench and create your first table through it.
We’ll explain how to install MySQL Workbench and get started with creating your first database and table, as well as how to use the tool to make sure your table structure is correct and can properly store the data you want it to store. Let’s get started!
In order to start working with databases, it is essential that you understand how tables work. In its most basic form, a table is composed of fields and records. Each field represents an attribute of data about your topic, for example, Name, Price, and Description.
Records are collections of related information that include information from different fields, such as Product Name and Price. In order to create tables using MySQL Workbench, you must have some knowledge of database basics; if you need help learning these skills, take a look at my beginner tutorial on understanding databases. You will also need some basic experience with PHP for creating your content management system (CMS) so that you can integrate it with your database.
If you’re not familiar with how to do so, I recommend taking an introductory course on making a CMS website before working through further tutorials. Once you’ve got these two essentials down, it’s time to move on to making a table! There are five steps involved in creating one: Define Field Types, Add Data Types, Define Primary Keys and Indexes, Apply Constraints and Validation Rules, and finally Generate Table Scripts/DDL Statements.
By going through each step one by one—and taking care not to skip any along the way—you should be able to successfully construct your very own tables!
Creating Your First Table In MySQL
Let’s create a table for storing employee information.
Click on SQL Editor on your left-hand menu
Type in: CREATE TABLE employees ( id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, name VARCHAR(255) NOT NULL, age DOUBLE PRECISION NOT NULL, department VARCHAR(20) DEFAULT ‘HR’ NOT NULL )
Then click on Execute SQL on your right-hand menu.
You can see here that I automatically created an integer column called id and gave it an auto-incrementing value.
Inserting Data into Tables
One of two things happens when you add data to your table: either you create new records or you update existing records. The quickest way to insert data into your table is by using auto-increment fields.
An auto-increment field is one where a number value will be automatically generated for each new record unless otherwise specified. To set an auto-increment value, select all columns that will be affected by that field and click on Properties under Edit Data. Set Values property if not already set, then click OK twice.
After entering data, you can preview it by clicking on View Data under any table’s name.
Editing Data in Tables
Once you’ve created your table, you can begin filling it with data. To edit records, simply double-click on any cell and start typing. Depending on what you type (for example, numbers only or letters only), MySQL Workbench will update that cell accordingly.
It’s important to note that adding new records is different from editing existing ones. You can add new records by clicking on rows and then entering new data into one or more cells (double-clicking also works).
Alternatively, you can double-click within an empty row between existing data points and enter new values for those fields. Once your data is typed into each cell, click OK to insert your entry. For example, if you need to add columns that contain last names, first names, and phone numbers, here’s how:
- Click on any blank row in column A
- Double-click on First Name
- Enter the first name
- Repeat step 3 for Last Name and Phone Number
Note that you only have one blank field—column C—and it will automatically expand once you type something into any of rows 2 or 3. You can then drag these fields into order by clicking on them as shown below
Deleting Data from Tables
When you need to delete rows or columns from a table, but don’t want or need to delete everything, you have a few options. You can use standard SQL statements, like DELETE, UPDATE, and TRUNCATE TABLE; you can use MySQL Workbench commands, or you can use third-party tools such as phpMyAdmin.
Whichever way you choose to remove rows from your tables depends on whether your data source is local (on your computer) or remote (on an online database). If it’s local, using phpMyAdmin is usually easier because it offers advanced search and sorting features.
If it’s remote, consider writing custom SQL code that includes two separate queries—one to retrieve deleted records and one to actually erase them.
Customizing the View of your Data
As you create your tables, you can choose from several different views that help you see and work with your data. This includes an editor view, which gives you an editable look at your data.
You can also choose to look at just one column of data as a list or table or create forms that make it easy for people who don’t know SQL (or want to learn) to query your database and get reports.
You might notice some differences if you’re using MySQL Workbench Personal Edition, but those differences aren’t significant enough that they’ll affect your ability to follow along with these steps. To start working with your tables, go ahead and select any table from inside Connectors Navigator. You can see all of your tables by clicking Data at the top of MySQL Workbench or by clicking Tables on Other Views.
How do I Query a Table in MySQL Workbench?
To view data from your database tables, select Tables > List Tables… from within Workbench. This will create a list of all tables and views in your database, including those created by other users on your server. Clicking on one of these entries will take you to its page in Details mode (below).
Alternatively, you can also click on an entry’s checkbox and use Ctrl+Down Arrow to navigate through them.
How do I get a list of tables in MySQL Workbench?
In order to open and create a new table, you must first get your list of tables. In order to do that,
- Click on Connection at the top of your screen
- Then select MySQL and click connect
- You will be prompted for your username, password, hostname, and database name
- Once you are connected you will see all of your databases listed in the MySql workbench as seen below
- Select which database you want and then scroll down until you see Tables. This will show you all of your tables inside of that specific database
- Click on the table name to open it and begin creating a new table
- You can right-click on top of any field or column and rename it if you wish.
Once you have created your new table, it will appear in the list so feel free to repeat steps 2-6 for each additional table that you want to create Briefly explain how a relational database is structured: Relational databases are composed of tables.
Tables are used to store data and their structure is designed around relationships between rows. A row can have many columns (aka fields) and one or more rows make up a table. Each column has specific data types, which define whether information should be stored as text or numbers.
Data should always be consistent with the data type assigned to it – if it is not, then an error message will occur when trying to insert data into that cell.
