To verify if the data was imported correctly, press on the table header while holding CTRL SHIFT. Next, you can modify the settings for date, columns (you can choose if what columns to load) and more. First, you have to access the Data Importer from the top menu Data Tools > Import Data From File.įrom the data importer you can select the file, the schema and the table. With DbSchema, importing a CSV file is way more easier. To check if the data was imported correctly, execute: SELECT * FROM table_name 2.Using DbSchema IGNORE 1 ROWS tells the database to ignore the first row from the document, the one that specifies column names.FIELDS TERMINATED BY ‘,’’ specifies that the comma is the delimiter.LOCAL tells the database that the file is expected to be found locally.Now, let’s break this query to understand better what’s happening: If everything worked, you can now execute the query that will import the data from the file: LOAD DATA LOCAL INFILE 'C:/Temp/product.csv' If you want to see what tables are in the database, execute SHOW TABLES.Then, execute USE database_name to select the desired database.Execute SHOW DATABASES in order to see all your databases.Open the command line by typing cmd in Start Įxecute the next query: mysql.exe -u root -pĪfter you insert the password you are ready to import your The first row contains the column names and the rest product properties.įirst of all, you have to enter the MySQL shell and select the database. This file contains 3 items for the product table and it looks like this: product_id,name,price At the moment I am using the following SQL command: LOAD DATA LOCAL INFILE filename. In this example I will use a file stored in C:/Temp, named product.csv. I then need to skip the next two columns in the CSV file and then map column 11 of CSV file to column 9 of MySQL table. In this article, I’m going to show you two ways to do this. -fields-enclosed-by: same as FIELDS ENCLOSED BY.Importing a csv file to your MySQL database is very simple.-fields-terminated-by: same as FIELDS TERMINATED BY.-lines-terminated-by: same as LINES TERMINATED BY.Practically, as I explained previously, this is useful to ignore header line. -ignore-lines=N: ignore first N lines in CSV file.testdb: replace it with the database you want to import CSV file into.Default to 3306, replace it with your server configuration. Try this one: mysqlimport -h localhost -P3306 -u root -p testdb -ignore-lines=1 -lines-terminated-by="\n" -fields-terminated-by="," -fields-enclosed-by="\"" -c title,author,created_at "/home/petehouston/data/articles.csv" The utility is created for one purpose, to handle import external data into MySQL.Īgain, you will get confused by looking at its documentation, too many options, and which are what, you ask? Phew…a lot of words just to explain a simple query! 2. So the next line: SET created_at = '%Y-%m-%d %H:%i:%s')is to convert time string into Date object and assign to created_at field in table. If there is a sign column name, it means the value of field is saved into that variable, and it’s a variable.īy using variable, we can transform CSV field data right before inserting into table. Next part of the query is the list of column names to import into table. On the other hand, if there is no header, you don’t need to add that query part. If there are headers, the first line in CSV file, then we should ignore it, and that is done through IGNORE 1 ROWS. LINES TERMINATED BY: to specify when row is complete.Especially, when you have string-type fields. ENCLOSED BY: to denote that value of field being put inside this pair of character.FIELDS TERMINATED BY: to tell SQL the character used for field separation.You need to pass CSV absolute file path right after INFILE, and the name of table to get imported after INTO TABLE. Take a look at following example: LOAD DATA INFILE '/home/petehouston/data/articles.csv' This is done by making use of LOAD DATA syntax.ĭon’t get confused about the complicated syntax definition. ) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=utf8mb4 `updated_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP, The table to get imported from CSV file has following structure: CREATE TABLE `articles` ( "Backup and restore MySQLDB","Pete Houston"," 12:15:32" It should be an easy task for any developer.įollowing is the CSV file that I use in this article. Hmmm…the 3rd method looks out of scope for this article, because you can use any programming language to write code to parse CSV file and import into MySQL database. Okay, get back to our task, that is, to import CSV file into MySQL, there are basically three methods. Take some time to read about CSV format if you don’t know it.
