How Can I Include Column Headers When Using MySQL's INTO OUTFILE?

Handling Headers in MySQL INTO OUTFILE

While using MySQL's INTO OUTFILE feature to export data to a file, it's possible to encounter a limitation where the resulting file doesn't include column headers. This can be inconvenient if you need to retain the column names after export.

Hardcoding Headers

The issue with INTO OUTFILE is that it doesn't automatically include headers. However, there's a workaround you can use to manually include them. You can hardcode the headers as the first row of your data like this:

SELECT 'ColName1', 'ColName2', 'ColName3'
UNION ALL
SELECT ColName1, ColName2, ColName3
FROM YourTable
INTO OUTFILE '/path/outfile'

In this example, we first select the column headers as a hardcoded string. Then, we use UNION ALL to combine it with the actual data from the YourTable. By doing so, the resulting file will now include the column names as the first line.
