无差错每一列必须有一个独特的名字，当你返回查询

Question

我想下面的SQL查询运行报告服务

select ca.callingpartynumber, ca.originalcalledpartynumber, case 
when calledpartylastname is not null then ca.calledpartylastname + ',' + calledpartyfirstname 
else p1.name end, 
p1.location, p1.dept, p1.title, 
case 
when callingpartylastname is not null then ca.callingpartylastname + ',' + callingpartyfirstname 
else p3.name end 
from calldata.calldetailreport ca 
join ps_bc_peoplesource_base p1 on ca.originalcalledpartynumber = replace(p1.bc_int_phone, '-', '') 
left outer join ps_bc_peoplesource_base p3 on ca.callingpartynumber = replace(p1.bc_int_phone, '-', '') 
where originalcalledpartynumber in (select replace(bc_int_phone, '-', '') internal_modified from ps_bc_peoplesource_base where bc_lan_id = 'f7c') 
--and datetimedisconnect between @startdate and @enddate --1221 

我得到这个错误 -

“具有相同键的项已被添加。”

Answer 1

你缺少列别名在你的SELECT查询两个case语句。由于SSRS仅使用列名作为键，而不是表+列，所以它会窒息。

SELECT ca.callingpartynumber, ca.originalcalledpartynumber, 
    CASE WHEN calledpartylastname IS NOT NULL 
      THEN ca.calledpartylastname + ',' + calledpartyfirstname 
     ELSE p1.name END AS calledpartylastname, 
    p1.location, 
    p1.dept, 
    p1.title, 
    CASE WHEN callingpartylastname IS NOT NULL
