Write and execute a SQL query to list all patient numbers and encounter ids which do not have any data (missing rows) in VisitSummary table. Order the result by patient number, encounter id. Write and execute a SQL query to list all patients whose information about race or gender has changed during their future visits. A future visit is defined as T1.encounter_id < T2.encounter_id. Your output should have patient number, old and new race values, old and new gender values, and the encounter ids. Write and execute a SQL query to list all the patient data for all encounters. Even if patient data is missing in other tables, you still need to list the patient_nbr and encounter_id in your output.
