How to export data from a MySQL table to a CSV file with custom delimiters?

To export data from a MySQL table to a CSV file with custom delimiters, you can use the following SQL query:

1

5
SELECT *
INTO OUTFILE '/path/to/filename.csv'
FIELDS TERMINATED BY '|' -- Use a custom delimiter, in this case '|'
LINES TERMINATED BY '\n' -- Use a custom line terminator
FROM your_table_name;


Replace /path/to/filename.csv with the path and filename where you want to save the CSV file. Replace your_table_name with the name of the table from which you want to export data.


This query will export the data from the specified MySQL table into a CSV file where columns are separated by the custom delimiter | and each row is terminated by a new line character \n.


Make sure that the MySQL user account you are using has the FILE privilege in order to write the file to the specified location.


What is the difference between exporting data from a MySQL table to a CSV file and an Excel file?

The main difference between exporting data from a MySQL table to a CSV file and an Excel file is the format in which the data is stored.

  • CSV file (Comma-Separated Values): CSV is a simple file format used to store tabular data, such as a spreadsheet or database. Each line of the file represents a single row in the table, with each value separated by a comma. CSV files are plain text files and can be easily opened and edited with a text editor or spreadsheet program.
  • Excel file (XLSX): Excel is a spreadsheet program developed by Microsoft. When exporting data to an Excel file, the data is stored in a proprietary binary format specific to Excel. Excel files can contain multiple sheets, formatting options, and functions, making them more versatile for complex data analysis and visualization.


In summary, exporting data to a CSV file is simpler and more lightweight, while exporting to an Excel file allows for more advanced features and functionality.


How to export data from multiple MySQL tables to a single CSV file?

To export data from multiple MySQL tables to a single CSV file, you can use a query that retrieves data from each table and then use the INTO OUTFILE statement to export the results to a CSV file. Here is an example of how you can achieve this:

  1. Connect to your MySQL database using a tool such as MySQL Workbench or the MySQL command line.
  2. Write a query that selects the data you want to export from each table. For example:


SELECT column1, column2 FROM table1 UNION SELECT column1, column2 FROM table2;

  1. Add the INTO OUTFILE statement at the end of the query to specify the path and filename of the CSV file where you want to export the data. For example:


SELECT column1, column2 FROM table1 UNION SELECT column1, column2 FROM table2 INTO OUTFILE '/path/to/outputfile.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n';

  1. Execute the query to export the data from the multiple tables to the specified CSV file.
  2. Check the CSV file to verify that the data has been successfully exported.
