CREATE TABLE authors (authid NUMBER, lname CLOB, fname CLOB)
CREATE TABLE inst (instid NUMBER, name CLOB, country CLOB)
CREATE TABLE papers (paperid NUMBER, title CLOB)
CREATE TABLE authorship (authid NUMBER, instid NUMBER, paperid NUMBER, authorder NUMBER)

Which paper has the most authors? Give me the paper title.
SELECT t2.title FROM authorship AS t1 JOIN papers AS t2 ON t1.paperid = t2.paperid WHERE t1.authorder = (SELECT MAX(authorder) FROM authorship)
SELECT "t2"."title" FROM "authorship" "t1" JOIN "papers" "t2" ON "t1"."paperid" = "t2"."paperid" WHERE "t1"."authorder" = (SELECT MAX("authorder") FROM "authorship")
