Schema: create table student (stuid varchar, fname varchar, lname varchar, PRIMARY KEY (stuid)); create table member_of_club (clubid varchar, stuid varchar, PRIMARY KEY (clubid)); create table club (clubname varchar, clubid varchar, PRIMARY KEY (clubname))
SQL: select count(distinct t1.clubname) from club as t1 join member_of_club as t2 on t1.clubid = t2.clubid join student as t3 on t2.stuid = t3.stuid where t3.fname = "eric" and t3.lname = "tai"
