Is there any way to get the correct conditions? Both options in MYSQL fail to achieve expected results

Question

SELECT cstmr_type FROM add_vehicle
WHERE cstmr_type = 'Visitor' AND cstmr_type = 'Hospital';

SELECT cstmr_type FROM add_vehicle
WHERE cstmr_type = 'Visitor' & 'Hospital';

Answer 1

Try to use the IN keyword

SELECT cstmr_type FROM add_vehicle WHERE cstmr_type IN ('访客', '医院')
