我有一个函数，输入参数在将数据插入xch.xch_transmas_patient表后将数据插入xch.xch_transmas_patient表我试图通过编写更新语句将数据更新到lt_transmas_patient表中并且我已经写了我在func中的代码是这样的正确与否
UPDATE lt_transmas_patient p
SET patient_first_name=pa.patient_first_name,
patient_last_name=pa.patient_last_name,
patient_birthdate=pa.patient_birthdate,
patient_email=pa.patient_email,
patient_mobile=pa.patient_mobile,
patient_home_phone=pa.patient_home_phone,
patient_updated_by=pa.patient_created_by,
patient_updated_on=pa.patient_updated_on,
patient_salutation=pa.patient_salutation,
patient_maritalstatus=pa.patient_maritalstatus,
patient_education_level=pa.patient_education_level,
patient_blood_group=pa.patient_blood_group,
patient_mother_tongue=pa.patient_mother_tongue,
patient_identification_mark=pa.patient_identification_mark
FROM xch.xch_transmas_patient pa
join xch.xch_transmasmap_mpi_link m on m.mpi_lk_xch_mpi=pa.patient_mpi and m.mpi_lk_partner_id=2
where p.patient_mpi=m.mpi_lk_external_mpi
and pa.patient_mpi=_patient_mpi;
