sql條件統計

select

count(distinct pmsinfo.id,pmsinfo.categoryid = 127 or null) msaj,
-- count(distinct pmsinfo.id,pmsinfo.categoryid = 128 or null) xsaj,
count(distinct pmsinfo.id,pmsinfo.causeofactionid in (2,3,4,5,6,7,8,9,10,11,12,13,14) or null) whgj_cause,
count(distinct casecustomer.id,casecustomer.identitycategoryid = 46 and customerfeature.featureid = 99  or null) wcnr_id,
-- count(distinct casecustomer.id,casecustomer.identitycategoryid = 46 and customerfeature.featureid = 100  or null) cjr_id,
-- count(distinct casecustomer.id,casecustomer.identitycategoryid = 43 or null) gsqy_id,
-- count(distinct casecustomer.id,casecustomer.identitycategoryid = 44 or null) jgdw_id,
(case when pmsinfo.categoryid = 135 then consultsum.amount else casesum.amount end) amount,
officebase.officename
from
pms_info pmsinfo
left join office_base officebase on pmsinfo.tenantid = officebase.id
left join fms_case_summary casesum on pmsinfo.id = casesum.infoid
left join fms_consult_summary consultsum on pmsinfo.id = consultsum.infoid
left join crm_case_customer casecustomer on pmsinfo.id = casecustomer.infoid
left join crm_case_customer_feature customerfeature on casecustomer.id = customerfeature.customerid
where pmsinfo.isdeleted = false and pmsinfo.tenantid = 5 and pmsinfo.typeid = 0
and pmsinfo.statusid in (1,2,3,4,5,6,7,12,13)
group by statistictime

結果：

(case when pmsinfo.categoryid = 135 then consultsum.amount else casesum.amount end) amount,

(case when pmsinfo.categoryid = 135 then date_format(consultsum.createtime,'%y%m%d') else date_format(casesum.createtime,'%y%m%d') end) statistictime

如果不等於，取casesum表的amount 和 casesum表的createtime。並取別名

date_format(consultsum.createtime,'%y%m%d') ：將日期格式化，例：（2019-01-10 00:00:00）—>20190110

count(pmsinfo.categoryid = 127 or null) msaj,      == 127時統計，注意加or null 不加不管用

count(pmsinfo.causeofactionid in (2,3,4,5,6,7,8,9,10,11,12,13,14) or null) whgj_cause,    等於後邊括號內任意乙個時統計，注意加or null 不加不管用

count(casecustomer.identitycategoryid = 46 and customerfeature.featureid = 99  or null) wcnr_id,    = 46 且 customerfeature.featureid = 99 時統計，注意加or null 不加不管用

count(distinct casecustomer.id,casecustomer.identitycategoryid = 46 and customerfeature.featureid = 99  or null) wcnr_id,

//根據casecustomer.id去重，並且當casecustomer.identitycategoryid = 46 和customerfeature.featureid = 99時統計

sql 條件判斷

case具有兩種格式。分支結構case語句和條件判斷case語句。分支結構case語句，類似於switch select case user name when 張三 then zhangsan when 李四 then lisi when 王五1 then wangwu else 找不到對應 en...
