    Your statement seems to be incomplete, it should contain ‘where’ clause to identify which record you want to update. Without it mysql may try to insert given values to all the rows of the table, which can lead to a primary key conflict.

    Try this and update id information which is mentioned in comment:

    def update(self):
    conn = mysql.connector.connect(host='localhost', user='root',
                                   password='root', database='pathology'
                                   )
    my_cursor = conn.cursor()
    my_cursor = conn.cursor(prepared=True)

    sql_update_query = """update pathology set num=%s, receivedate=%s, patientname=%s, pathologynum=%s, gender=%s, age=%s, inspechospital=%s, casenum=%s, specimenclass=%s, bed=%s, diagnosis=%s, clinicaldiagnose=%s, inspecdoctor=%s, pathologydoctor=%s, sampledate=%s, reportdate=%s where id = %s"""

    data_tuple = (
        self.var_sys_num.get(),
        self.var_rec_date.get(),
        self.var_patient_name.get(),
        self.var_path_num.get(),
        self.var_gender.get(),
        self.var_age.get(),
        self.var_sub_hospital.get(),
        self.var_case_num.get(),
        self.var_specimen_level.get(),
        self.var_bed.get(),
        self.var_diagnosis.get(),
        str(contents),
        self.var_submit_doctor.get(),
        self.var_simple_date.get(),
        self.var_path_doc.get(),
        self.var_report_date.get(),
        # your id/column info against which you want to update
    )

    my_cursor.execute(sql_update_query, data_tuple)
