The table into which the data is loaded: I NTO TABLE countries.The file from which the data is loaded: LOAD DATA INFILE 'countries.csv'.Now we can load the countries table with the data from our CSV file. After completing these, we create a new table using the CREATE TABLE command. And the USE command followed by a schema name ensures that we work inside the newly created schema. The CREATE SCHEMA command followed by a schema name creates a new schema named data. Last, we’ll create a new table using the CREATE TABLE command. Then we’ll execute the USE command to make sure you are inside your newly created schema. So first let’s create a new schema using the CREATE SCHEMA command. Importing a CSV Fileīefore importing a CSV file, you need to create a table manually with proper data types for each column. Please note that both the MySQL Command Line Client and the standard command line tool provide the same mysql prompt. You can connect your database by executing the mysql -host=localhost -user=username -password command and providing a password: Connecting a DatabaseĪssuming that you have a working MySQL database installed on your computer, you can use the MySQL Command Line Client (shown below): Importing a CSV File into MySQL Using Command Lineįollow the steps below to import a CSV file into the MySQL database via the command line tool. One is to use a command line tool and another is to use a Graphical User Interface, or GUI. In the MySQL database, there are two options to import a CSV file. Importing a CSV File into a MySQL Database That’s why CSV files, despite their simple nature, play such a crucial role in data processing and analysis. It is much better than creating a table and inserting the data manually. The process of CSV file import is fast and straightforward. Hence, CSV is a very common file format for transferring data. Also, various online data resources and database tools offer data uploads and downloads in CSV format. We can export data in a CSV file format from one database and import it in this format into another database (e.g. Since then, CSV files have been used to transfer data between databases. Relational databases and CSV files were first developed around the same time in the 1970s. Please note that any value containing a comma character is enclosed in double quotation marks.Īnd here is a table based on the countries.csv file: idĬSV files use a simple text format to store data. The first row stores comma-separated column headers, and the following rows store comma-separated values. It might not be as clear as a table, but you can definitely see the pattern. Let’s look at a sample CSV file called countries.csv that we’ll later import into the MySQL database. For example, the value 12.34 goes without double quotation marks, but the value 12,34 must be written as "12,34" to prevent it from being considered as two values ( 12 and 34) instead of one value ( 12,34). It is treated as a special case: the value is wrapped in double quotation marks. Now you may wonder what happens if a value contains a comma character. Typically, the first row of a CSV file stores column headers and the following rows store data. Usually, the column values are separated by a comma (hence the name, comma-separated values), but you can use other separators, such as a semi-colon or a tab. Each row of a CSV file represents a row of a table. A CSV file is a text file that stores tabular data. About CSV FilesĬSV stands for “Comma-Separated Values”. So, let’s get started with our review of the CSV file format. It’s not necessary for either course, but having a MySQL database on your computer will give you something to practice on later.
