How to export / dump a MySql table into a text file including the field names (aka headers or column names)


In MySql's interpreter, it's very easy to dump a table to the screen along with its field names.

There seems to be no simple way to export a table to a tab-delimted or CSV outfile including its column headers.

I'm trying to do this using only SQL or the Linux command line, without writing a program in another language.

Thank you


Solution

  • Piping the query to the commandline client outputs a tab separated list with the column names as the first line
