IGNORE 1 ROWS: It is used to ignore the first line of the CSV file, which has column headings that are not required to import into the table. LINES TERMINATED BY '\r\n': It is used to terminate each line of the CSV file. LOAD DATA INFILE 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/address_book.csv'įile Location: It specifies the location of the CSV file into the system.įIELD TERMINATED BY ',': It is used to indicate the field of the file, which is terminated by a comma.ĮNCLOSED BY '"': It is used to specify the field of the file enclosed by double quotation marks. For example, the below data structure explains it more clearly: The structure of the CSV file contains a list of data that is separated by a comma operator. ![]() ![]() A CSV file cannot allow saving formulas in this format. We can use the CSV file with a various spreadsheet program like MS Excel or Google Spreadsheets. This file is very beneficial when we need to export complex data from one application to a CSV file, and then import the file data into another application. Generally, it is used with the comma character to delimit (separate) data, but can also use other characters, like semicolons. Sometimes it is also called as character separated values. It is mainly used to exchange data between different applications. A CSV stands for comma-separated values, which is a plain text file that contains the list of data and allows us to save it in a tabular format. MySQL has a feature that allows us to import the CSV file into a database or table. Module.exports = ( sequelize, DataTypes) => else if ( → ← prev MySQL Import CSV File in Database/Table How can we import CSV files in MySQL database or table? Our table will have an auto-incrementing id and the book title. In the models’ folder create a file called books.js as we will be working with books’ data. Go ahead and delete the seeders and migrations folder, we don’t need that. In my case it looks as follows: you will have to change the values according to your SQL setup, but the host and dialect will be the same as mine. Now we have to replace the above values with correct values. Open the config/config.json file there will be a key called development, like this. I have called mine fakedb and, as you can see in the image below, it is empty for now. Open your MySQL workbench and create a database. Now we will be connecting to our database. Your folder should be looking like this now. Now run sequelize init in terminal to get started with sequelize. js If you see a message that the server started on port 3000, then you did everything right. After doing that we started the server on port 3000.Īnd now run nodemon app. ![]() Here we are importing the express module and initializing it with an app variable. Following lines are to make sure our app can parse the json dataĬonsole.log( 'Server started on port 3000') And write the following code in the file. Npm i express dotenv sequelize sequelize- cli mysql2Ĭreate a file called app.js in your project’s root folder. Now install some libraries that will be needed by typing the following: ![]() Setting up the project and database: Create an empty folder and run the command git init inside of it using your terminal. This means that no excess space will be needed to store the file. The important thing here is that we are not going to store the file anywhere on the system/server (other tutorials available online first need you to upload files to the server which does not scale well). Once our database and the API to create data are done, we will create some sort of functionality that will convert the CSV file to JSON. You can use whatever database paradigm you prefer. In this article I am going to use MYSQL, along with sequelize ORM, to create a project with an attached database. Data is then able to be parsed and saved to the database. Sometimes when a large number of rows are to be added to a database, instead of adding values one by one, websites provide the option to upload a CSV (comma-separated values) file.
