The structure of your databases is made up of tables.Tables contain the information that is entered into the database, and can be created to suit almost any data storage need.If you only have a few different entries to save, it's easy to create a table.The first step is to get started.
Step 1: You can open your database.
You must have a database to house a table.You can open your database by typing USE at the prompt.If you don't remember the name of your database, you can list it on the server.If you don't have a database yet, you can create one by typing.The database name can't contain spaces.
Step 2: Understand the basic data types.
A certain type of data is stored in the table.The ability to interact with them in different ways is provided by this.Depending on the needs of your table, the data types you use will be different.There are many more types than these, but you can use them to make a basic table.The total number of digits and the number after the decimal are used to define the data type.The numbers would be stored as "0000.00".The data type for text and strings is char.A limit for the number of characters is usually defined.VARCHAR can be used to vary the size.Phone numbers often contain symbols and do not interact with numbers, so they should be stored in this data type.Dates are stored in the format YYYY-MM-DD.If you need to store someone's age as opposed to their actual age, you can use this.
Step 3: You should create a table.
All of your fields will be created in one command to create your table in the command line.You use the CREATE TABLE command to create tables.To create a basic employee record, you need to use the following command.Each time, the number increases.You can easily reference employees with other functions.You can set a limit for VARCHAR so that the user can't input strings that are too large.First and last names are limited to 20 characters.The phone number entry is stored in VARCHAR so that symbols are handled correctly.
Step 4: Make sure your table was created correctly.
You will receive a message once you create your table.You can use the DESCRIBE command to make sure that all the fields you want are included.Refer to the chart that appears to check the structure of your table if you type DESCRIBE database.
Step 5: It is possible to create a table using a programming language.
You can use a simplePHP file to create a table if you want to administer your database through a website.The database is on your server.The following code will replace the connection information with your own."CREATE TABLE employees ( id NOT NULL PRIMARY KEY AUTO_ INCREMENT, lastname VARCHAR(20), phone VARThere is an error in the connection.
Step 6: You can add a single entry to your table.
From the command line, you can enter data into your table.You can use one command to enter all of the related fields.You need to make sure that each value has a single quote around it.
Step 7: Add more than one entry at once.
If you have all of the data in front of you, you can use one INSERT into command to insert multiple entries.If you want to separate the value sets, use a separator: INSERT into employees (id, last name, firstname, phone, dateofbirth) VALUES.
Step 8: You can display your table.
You can display your table to see how everything looks once you've inserted a few entries.You can see if you missed anything or if something is in the wrong place.You can display the table created above it by typing from employees.Adding filters to the search will allow you to perform more advanced displays.If you want to return the table sorted by date of birth, you can type SELECT last name, firstname, dateofbirth from employees and then reverse the order of the results.
Step 9: You can enter data using a form.
There are other ways to enter data.A form on a web page is one of the most common.This guide will show you how to create a basic form to fill out your table.
