A proof of the orthogonality relation for the Askey–Wilson polynomials is given by using a generating function for the Askey–Wilson polynomials and the uniqueness of a rational function expansion. We further use the orthogonality relation for the Askey–Wilson polynomials and a q q -series transformation formula to evaluate a general q q -beta integral with eight parameters. The integrand of this q q -beta integral is the product of two terminating 5 ϕ 4 _5\phi _4 series and the value is a 10 ϕ 9 _{10}\phi _9 series.
