The best I've been able to come up with involves some shell scripting.
If you're running Linux, using unpacked MyISAM tables, and have some
scripting ability from whatever language you're writing your application
in, you can run this in your MySQL directory:
strings -f *.MYD | grep <search string> | cut -f1 -d'.' | sort
-u
It will give you back the table names that have that string somewhere
inside them. Then in your scripting language you can check the columns
on just the tables that the shell script returned. Note that it is NOT
fast at all. My 1.7GB of database takes about 10 minutes to crunch
through the data.
If you're going to do something like this make sure you understand the
security ramifications of running shell scripts with user input and how
to secure it in your language of choice.
