SQL判斷 一個字段為空時,取出另一個字段數據

 

table = db.exec_sql("""insert into dw.part_subject (
                                part_name,
                                part_type,
                                part_status,
                                reg_date,
                                source_id,
                                source) 
                            select 
                                case when iccard_name is not null then iccard_name else name end, '0',
                                '0',
                                create_datetime,
                                id,
                                '' 
                            from ods.sl_account_560;""")
