For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Saving a MySQL query results to your local disc for Excel

Do you want to run a database query on a remote server and save the results into a text file on your LOCAL disc - i.e. the disc of the computer at which you're seated and not the disc of the server that's in a remote location?

It's not as easy as you think it should be. Because of the security risks involved, you cannot save to LOCAL OUTFILE from a SELECT in MySQL, even though you can read from LOCAL INFILE in a LOAD. Reading in known data is OK, but saving what could be malicious or confidential information away from the server is quite a different kettle of fish.

Solution?

One possibility is to wrap your query in a web page, and allow your browser's facilities to store the result set locally. In other words, to put up a form and have the user enter his query in that. When submitted, the user's browser deals with the security issues of saving the data locally using the security preferences already set up by the user for his browser..

I've written a sample script to demonstrate the saving of a query result to a local .csv file. You could change the comma to a tab separator for your own use and that way you'll get a page that save a databases to your local system suitable for import to spreadsheets such as Excel.

UPDATE - Summer '07. See also additional comments about the header() function and changes needed to the original script for new PHP versions!. Thank you.
