MySQL Create Table

MySQL uses Tables to store and Manage Data, and this article shows how to Create Tables with an example. Here, we will use both the command prompt and Workbench for the Create Table statement.

The table is a combination of Rows and Columns. We have to use the Create Table Statement to create a new one.

MySQL Create Table Syntax

The basic syntax to create a table is as shown below:

    Column_Name1 Data_Type(Size) [NULL | NOT NULL],
    Column_Name2 Data_Type(Size) [NULL | NOT NULL],
    Column_NameN Data_Type(Size) [NULL | NOT NULL]

Let us see the individual items from the MySQL Create table syntax:

  • TableName: Please provide a Unique name. It throws an error if the name already exists.
  • Column_Names: Unique or distinct Column Names required.
  • Data Type: A valid Data type for every individual column. For example, Int, Varchar, float.
  • Size: Please provide a valid integer number here
  • NULL or NOT NULL: If the NULL option is selected, the column accepts both normal values and NULL values. Otherwise, it throws an error stating the Column should not be empty.

Create Table using Command Prompt

Before we start creating a table in Company Database, Let us see the list of existing ones inside the database. To get this information, use the following command.


The below screenshot shows the available ones in the MySQL database.

Available ones in Command Prompt 1

As you see, the company Database had no existing ones. For the demo purpose, we constructed a new called sales using MySQL create table statement.

   Product_Name VARCHAR(100) NULL,
   Product_Description TEXT

From the below screenshot, see that the Command was executed successfully.

Now, let’s see the list of available ones in the company database. And notice the sales name in the list.

Workbench Example

This time, we use the below-shown code to create Customers tbl inside the Company Database.

USE company;
CREATE TABLE customers (
    First_Name VARCHAR(50) NULL,
    Last_Name VARCHAR(50) NULL,
    Education VARCHAR(50) NULL,
    Profession VARCHAR(50) NULL,
    Yearly_Income INT NULL,
    Sales FLOAT(10, 2) NULL,

NOTE: Before you start creating a new one, It is always advisable to check if it exists or not.

Workbench Example 4

In the above code, we declared 7 Columns in our newly created table in MySQL:

  • Our first column is CustID of Integer data type, and it won’t allow NULL values. We also defined this column as Auto Incremental. (This is optional If you want, You can delete the Auto_Increment portion)
  • FirstName, LastName, Education, and Profession columns belong to the Varchar data type, and it won’t allow NULL values. We also assigned the size to 50. It means these columns accept up to 50 characters
  • The sixth column is the Yearly Income of INT data type, and it allows NULL values.
  • Sales columns belong to float data type, and it allows NULL values.

From the below screenshot, see that the command was executed successfully. Now, you can see the Newly created one under the Tables folder.

Available under the Database Schema Navigator 5

TIP: If you didn’t find the newly created table, Please click on the refresh button beside the SCHEMAS

How to find Table Definition?

If you want to find the existing definition, right-click on the name and select the Table Inspector option from the context menu.

Inspector Option in workbench 6

Once you select that option, a new tab opens with all the information. Please go to the DDL tab to see the definition.

Check whether the Table name exists or not.

Let us see what happens if we create a table in MySQL with an existing name. From the below screenshot, you can see it is throwing an error saying: TableSales already exists.

USE company;
    Name VARCHAR(50) NULL,
    Country VARCHAR(50)    
Already Exists Error 1050

NOTE: It is always advisable to check whether the table name exists already or not

If you have the privilege to see the list of available ones in a database, then use the SHOW TABLES command. If it is not the case, use the below option.

The following statement only executes MySQL Create Table Statement if the sales are not available in the company database.

USE company;
    Name VARCHAR(50) NULL,
    Country VARCHAR(50)    
If Not Exists Create Command 20

Try different names using create table command

USE company;
    Name VARCHAR(50) NULL,
    Country VARCHAR(50)
