I have 8 large, complex queries:

q1, q2, q3, q4, q5, q6, q7, q8

Each one queries its own respective table:

t1, t2, t3, t4, t5, t6, t7, t8

Suppose there are names as part of each table, composed of three fields ---
first_name, middle_name, last_name.

I want to know the name set(s) common to all the 8 query results.

I will alter the queries, incrementally (all 8 querries), until I get a full
name set collection totalling around 100 names.

In other words, what will emerge are 100 names common to all the query
results.

Any thoughts on how best to do this?

One approach would be to combine all the 8 queries into one single
super-large query.  Yikes.

Thanks,
Nicholas
