BIRT 报告：Oracle 查询：如何获得一个 Personid 的单行输出

Question

表：LABORCRAFTRATE：它有两个 cloumns

LABORCODE CRAFT
--------- ---------
SP51894   Replace
SP51894   Repair
SP51894   Connect
SP51894   MET1

表格：PERSON：5 列

PERSONID LOCATION STATUS FIRSTNAME LASTNAME
-------- -------- ------ --------- ---------
SP51894  Delhi    ACTIVE Smita     Patil

所需输出：7 列

PERSONID LOCATION STATUS FIRSTNAME LASTNAME Connection Replacement
-------- -------- ------ --------- -------- ---------- ------------
SP51894  Delhi    ACTIVE Smita     Patil    Yes        Yes

我的查询：

select distinct
       person.personid, person.location, person.status, person.firstname, person.lastname,
       case when (laborcraftrate.craft = 'CONNECT') then 'Yes' else null end as connection,
       case when (laborcraftrate.craft = 'REPLACE') then 'Yes' else null end as replacement  
from   maximo.person, maximo.laborcraftrate 
where  ((person.personid like '%PM02056%'))
and    person.personid= laborcraftrate.laborcode and person.status in ('ACTIVE','INACTIVE')
and    laborcraftrate.craft in ('CONNECT','REPLACE')
group by person.personid, person.location, person.status, person.firstname, person.lastname, laborcraftrate.craft;

此查询返回两行：

PERSONID LOCATION STATUS FIRSTNAME LASTNAME Connection Replacement
-------- -------- ------ --------- -------- ---------- ------------
SP51894  Delhi    ACTIVE Smita     Patil    Yes        
SP51894  Delhi    ACTIVE Smita     Patil                Yes

如何获得一个 Personid 的单行输出？ Distinct 在 BIRT 中不起作用.. :(

Answer 1

需要条件聚合。您可以在返回 Connection 和 Replacement 列以及

时应用聚合

 GROUP BY PERSON.PERSONID, PERSON.LOCATION, PERSON.STATUS,PERSON.FIRSTNAME, PERSON.LASTNAME

条款：

SELECT P.PERSONID, P.LOCATION, P.STATUS, P.FIRSTNAME, P.LASTNAME,
       MAX(CASE
           WHEN (UPPER(L.CRAFT) = 'CONNECT') THEN
               'Yes'
           ELSE
                NULL
           END ) AS Connection,
       MAX(CASE
           WHEN (UPPER(L.CRAFT) = 'REPLACE') THEN
               'Yes'
           ELSE
                NULL
           END ) AS Replacement
  FROM maximo.PERSON P
  JOIN maximo.LABORCRAFTRATE L ON P.PERSONID = L.LABORCODE
 WHERE ((P.PERSONID LIKE '%SP51894%'))
   AND P.STATUS IN ('ACTIVE', 'INACTIVE')
   AND UPPER(L.CRAFT) IN ('CONNECT', 'REPLACE')
 GROUP BY P.PERSONID, P.LOCATION, P.STATUS, P.FIRSTNAME, P.LASTNAME;
