Hi,
the question is not really clear. Do you mean the following?
a = 'test'; % input from user, e.g., by GUI or input
% use the variable a as database name:
d = database(a, ...);
This works fine as long as the user passes a "known" database name ...

The tables are specified when you read data, e.g.
tableName = 'customers';
curs = exec(['SELECT * FROM ' tableName]);
