For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
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.
