I have several databases that are used to collect data for different
client-projects. My intention was to collect the data, and administer
mySQL so each client could see only their data. Each of these
databases used to collect data have the same tables. There are other
databases which are available to all the users which contain common
information.

The command "show databases" lists all of the databases (visible to
the particular user) and not the one's I would like to display (the
databases used to collect data). Is there a way to nest a single
mySQL command to show only the databases that have the same particular
table?

yes, potentially you can write a stored procedure to do this. you'll save the
procedure in each database separately of course.

You mean something like this?

SELECT DISTINCT TABLE_SCHEMA FROM information_schema.TABLES WHERE
TABLE_NAME = 'the_table_name_you_look_for'

Except that will show tables not databases.

Of course it shows databases, TABLE_SCHEMA contains the name of the
database.
