![]() This only works if the data types are characters. However, there are a few issues with this: This would mean your column headings would be shown in the file: "id","first_name","last_name" So, your query would look like this: SELECT 'id', 'first_name', 'last_name' One commonly-mentioned way is to use a UNION ALL to select the column headings and the data. How can you get column headings to display? Unfortunately, there’s no easy option you can enable. You might have noticed that there are no column headings in the output file. You just add the INTO OUTFILE keyword to the end of a SELECT query and specify some parameters. So that’s how you can generate a CSV or text file in MySQL. The text in the file is: "1","John","Smith" If we run this statement, we can check the file, which will look like this: LINES TERMINATED BY: this indicates the character(s) that are used to end a line and start a new line.įor example, to select the data to a CSV file and enclose each field in a double quote: SELECT id, first_name, last_name.ENCLOSED BY: this indicates the character(s) that will be used to surround each field.FIELDS TERMINATED BY: this indicates the character(s) that are used to end a field.You can change the parameters of this INTO OUTFILE keyword to change how the file is written. This is the default behaviour, but it can be changed.Ĭhanging Parameters to Set Comma Separated Values I’ll explain more about resolving this later in this guide.įor now, assuming you can run the statement to generate the file, it will look like this:Īs you can see, the fields are separated by tabs. The MySQL server is running with the –secure-file-priv option so it cannot execute this statement What happens if you get this error (like I did)?Įrror Code: 1290. This will create a new file called myoutput.txt that contains the results of this query, in a folder called temp. We simply add the words INTO OUTFILE, followed by a filename, to the end of the SELECT statement.įor example: SELECT id, first_name, last_name There’s a built-in MySQL output to file feature as part of the SELECT statement. We could copy and paste them, but that’s slow and manual. ![]() We may see these results in the output of our command line or in the IDE, such as MySQL Workbench. Let’s use a simple example of a SELECT statement for this. You can do this using an IDE or the command line, using a built-in MySQL command. Do you need to save your results from a MySQL query to a CSV or text file? ![]()
