select * from report_tt_storage_cost_record where customer_code = ADDS这条SQL语句写的对吗

这条SQL语句有问题。在SQL语句中,字符串需要使用单引号或双引号括起来,所以应该将ADDS用单引号或双引号括起来,例如:
```
select * from report_tt_storage_cost_record where customer_code = 'ADDS';
```
或者
```
select * from report_tt_storage_cost_record where customer_code = "ADDS";
```

请优化这段代码select * from ( select order_bill_id , counterfoil_no , counterfoil_amt , acceptor , company_id , cert_no , company_name , rate , expiry_date , transaction_amt , create_date , update_date , partner_id , partner_name , order_status_code , order_status_msg , transaction_date , tenant_id , platform_id , channel_id , share_profit , settle , row_number()over(partition by order_bill_id order by update_date desc )rn from (select * from dwd_mec_adds_order_bill_inc where dt='2023-06-07' union all select * from dwd_mec_adds_order_bill_inc where dt='2023-06-06')t )r where rn=1
这段代码可以进行如下优化:
1. 使用`UNION ALL`的语句可以合并为一个子查询,避免了多次扫描表的开销。
2. 在子查询中使用`WHERE`条件过滤查询日期,避免了查询全表的开销。
3. 可以使用具体的列名代替`SELECT *`,避免了不必要的数据传输开销。
综上所述,可以优化成如下代码:
```
SELECT order_bill_id, counterfoil_no, counterfoil_amt, acceptor, company_id, cert_no, company_name, rate, expiry_date, transaction_amt, create_date, update_date, partner_id, partner_name, order_status_code, order_status_msg, transaction_date, tenant_id, platform_id, channel_id, share_profit, settle
FROM (
SELECT order_bill_id, counterfoil_no, counterfoil_amt, acceptor, company_id, cert_no, company_name, rate, expiry_date, transaction_amt, create_date, update_date, partner_id, partner_name, order_status_code, order_status_msg, transaction_date, tenant_id, platform_id, channel_id, share_profit, settle, ROW_NUMBER() OVER (PARTITION BY order_bill_id ORDER BY update_date DESC) rn
FROM dwd_mec_adds_order_bill_inc
WHERE dt IN ('2023-06-06', '2023-06-07')
) t
WHERE rn = 1;
```
这样可以使代码更加简洁,同时也可以提高查询效率。
insert overwrite table discountdw.dwd_sd_adds_order_bill_inc partition(dt = '2023-06-06') select t1.order_bill_id, t1.counterfoil_no, t1.acceptor, date_format(to_utc_timestamp(cast(t1.expiry_date as bigint) ,'GMT-8'),'YYYY-MM-dd'), t2.company_id, t1.cert_no, t1.company_name, t1.third_order_id, t1.counterfoil_amt/10000, t1.transaction_amt/10000, t1.rate, '3bp' as service_tariffing, ((DATEDIFF(to_utc_timestamp(t1.expiry_date ,'GMT-8'),to_utc_timestamp(t1.transaction_date ,'GMT-8') ) + adjust_days)* 0.0003 *(counterfoil_amt))/ 360 as service_fee, 360 as total_days, DATEDIFF(to_utc_timestamp(t1.expiry_date ,'GMT-8'),to_utc_timestamp(t1.transaction_date ,'GMT-8') ) + adjust_days as modulation_date, t3.channel_type, t3.bank_name, date_format(to_utc_timestamp(cast(t1.transaction_date as bigint) ,'GMT-8'),'YYYY-MM-dd'), t1.order_status_code, t1.order_status_msg, t4.fee_amt, t4.status, t1.tenant_id, t5.revenue, to_utc_timestamp(cast(t1.create_date as bigint) ,'GMT-8'), to_utc_timestamp(cast(t1.update_date as bigint) ,'GMT-8') from (select * from discountdw.ods_adds_order_bill_inc where dt ='2023-06-06' and channel_id=101110004 )t1 left join (select * from mecdw.ods_company_full where platform_id='sdpjw')t2 on t1.cert_no=t2.cert_no and t1.tenant_id=t2.tenant_id left join discountdw.dim_adds_product_full t3 on t1.partner_id=t3.partner_id and t1.product_id=t3.product_id left join (select * from mecdw.dwd_sc_fee_record_full where dt='2023-06-06' and biz_type=2 ) t4 on t1.order_bill_id=t4.third_id left join (select * from discountdw.ods_sd_order_ext_inc where dt='2023-06-06') t5 on t1.order_bill_id=t5.order_bill_id left join sdpjwdw.dim_holiday_info_full t6 on date_format(to_utc_timestamp(t1.expiry_date ,'GMT-8'),'YYYY-MM-dd') = t6.civic_holiday ;
这是一条 SQL 语句,看起来比较长。以下是一些可以考虑优化的建议:
1. 将表名、字段名等缩短,以减少字符数和提高可读性。
2. 将复杂的表连接操作拆分成多个子查询,以降低查询复杂度。
3. 对于一些计算操作,可以考虑使用内置函数或自定义函数,以简化代码并提高可维护性。
4. 对于一些重复的操作,可以将其提取成变量或常量,以减少重复代码。
综上所述,优化后的 SQL 可能类似于以下代码(仅供参考):
