这是一个 SQL 查询语句,它的作用是查询在指定时间段内投保且未退保、未作废、有分期计划的保单对应的未出账单的缴费计划信息。具体来说,它会先在 gupolicymain 表中查找在指定时间段内投保且未退保、未作废、有分期计划且创建者不是邮箱形式的保单号,然后在 gupolicypaymentplan 表中查找对应保单号的缴费计划信息,其中满足计划日期早于指定日期且未出账单。

select c.* from upiccore.gupolicypaymentplan c where c.policyno in (select m.policyno from upiccore.gupolicymain m where m.inputdate > to_date('2022-04-12 00:00:00', 'yyyy-mm-dd hh24:mi:ss') and m.flowid in (select p.program_id from upiccore.c_program p where p.create_user not like '%@%') and m.validind = '1' and m.surrenderind='0' and m.cancelind='0' and m.installmentno is not null) and c.plandate < to_date('2023-05-12 00:00:00', 'yyyy-mm-dd hh24:mi:ss') and c.billno is null; 优化下
这个 SQL 查询语句可以进行优化,可以使用 JOIN 进行优化,如下所示:
```
SELECT c.*
FROM upiccore.gupolicypaymentplan c
JOIN upiccore.gupolicymain m ON c.policyno = m.policyno
JOIN upiccore.c_program p ON m.flowid = p.program_id
WHERE m.inputdate > to_date('2022-04-12 00:00:00', 'yyyy-mm-dd hh24:mi:ss')
AND p.create_user NOT LIKE '%@%'
AND m.validind = '1'
AND m.surrenderind = '0'
AND m.cancelind = '0'
AND m.installmentno IS NOT NULL
AND c.plandate < to_date('2023-05-12 00:00:00', 'yyyy-mm-dd hh24:mi:ss')
AND c.billno IS NULL;
```
在这个优化过的查询语句中,使用了 JOIN 连接三个表,避免了使用子查询,可以更加高效地执行。同时,将一些条件的判断移到 JOIN 的 ON 子句中,也可以提高查询效率。
select a.InsuredAddressCountry, a.insuredaddressstate, a.insuredaddresscity, a.insuredaddressdistrict, a.policyno, c.countrycode as 国家, c.regioncode as 省, c.area as 市, c.clientdistrict 区县, a.endorseqno, a.insuredcode, a.insuredtype from guPolicyCopyRelatedParty a, GSClientCorporate c where (((a.insuredaddresscity is not null and a.insuredaddressstate is not null and (select b.upperareacode from ggcountry b where b.countrycode = a.insuredaddresscity and b.arealevel = '3' and b.upperareacode = a.insuredaddressstate) is null) or (a.insuredaddressstate is not null and a.insuredaddresscountry is not null and (select b.upperareacode from ggcountry b where b.countrycode = a.insuredaddressstate and b.arealevel = '2' and b.upperareacode = a.insuredaddresscountry) is null) or (a.insuredaddressdistrict is not null and a.insuredaddresscity is not null and (select b.upperareacode from ggcountry b where b.arealevel = '4' and b.countrycode = a.insuredaddressdistrict and b.upperareacode = a.insuredaddresscity) is null)) or (a.insuredaddresscountry is null and (a.insuredaddressstate is not null or a.insuredaddresscity is not null or a.insuredaddressdistrict is not null)) or (a.insuredaddresscity is not null and a.insuredaddressstate is null) or (a.insuredaddressdistrict is not null and (a.insuredaddressstate is null or a.insuredaddresscity is null))) and a.insuredtype in ('2', '4') and a.insuredcode = c.clientcode order by a.insuredaddresscountry,a.insuredaddressstate,a.insuredaddresscity,a.insuredaddressdistrict; 此sql如何根据where后的条件进行判断给自定义的返回结果赋值
您可以在 SELECT 语句中使用 CASE 表达式来根据条件返回自定义结果。例如,以下 SQL 将根据 where 条件中的查询条件返回不同的结果:
```
SELECT a.InsuredAddressCountry, a.insuredaddressstate, a.insuredaddresscity, a.insuredaddressdistrict, a.policyno, c.countrycode as 国家, c.regioncode as 省, c.area as 市, c.clientdistrict as 区县, a.endorseqno, a.insuredcode, a.insuredtype,
CASE
WHEN (a.insuredaddresscity IS NOT NULL AND a.insuredaddressstate IS NOT NULL AND (SELECT b.upperareacode FROM ggcountry b WHERE b.countrycode = a.insuredaddresscity AND b.arealevel = '3' AND b.upperareacode = a.insuredaddressstate) IS NULL) OR (a.insuredaddressstate IS NOT NULL AND a.insuredaddresscountry IS NOT NULL AND (SELECT b.upperareacode FROM ggcountry b WHERE b.countrycode = a.insuredaddressstate AND b.arealevel = '2' AND b.upperareacode = a.insuredaddresscountry) IS NULL) OR (a.insuredaddressdistrict IS NOT NULL AND a.insuredaddresscity IS NOT NULL AND (SELECT b.upperareacode FROM ggcountry b WHERE b.arealevel = '4' AND b.countrycode = a.insuredaddressdistrict AND b.upperareacode = a.insuredaddresscity) IS NULL) THEN '条件1'
WHEN a.insuredaddresscountry IS NULL AND (a.insuredaddressstate IS NOT NULL OR a.insuredaddresscity IS NOT NULL OR a.insuredaddressdistrict IS NOT NULL) THEN '条件2'
WHEN a.insuredaddresscity IS NOT NULL AND a.insuredaddressstate IS NULL THEN '条件3'
WHEN a.insuredaddressdistrict IS NOT NULL AND (a.insuredaddressstate IS NULL OR a.insuredaddresscity IS NULL) THEN '条件4'
ELSE '其他条件'
END AS 自定义结果
FROM guPolicyCopyRelatedParty a, GSClientCorporate c
WHERE a.insuredtype IN ('2', '4')
AND a.insuredcode = c.clientcode
ORDER BY a.insuredaddresscountry, a.insuredaddressstate, a.insuredaddresscity, a.insuredaddressdistrict;
```
在上述查询中,当符合条件1时,返回“条件1”,当符合条件2时,返回“条件2”,以此类推。您可以根据自己的需求修改条件和返回值。
