i want make mothly statistic (sum on logtypes in contactlog) , include clients have in client list id 1. output shows clients have no record clientcontactlog. need with.. data have input need show 0 on clients has no record.

output should be

clientname | sum(logtype1) client11   | 2 client12   | 0 client13   | 0 client14   | 1 client15   | 1

thanks input , help

pretty sure mean count(logtype), not sum(logtype), since summing date makes no sense whatsoever. in case, can asking for.

select clientname, isnull(ct, 0) logcount clientgroup cg inner join clients c     on cg.clientid = c.clientid left join (     select logid,          count(*) ct     clientcontactlog     group clientid     ) cl

notes:

  • i assumed clients table containing client name.
  • i not looking @ contactlog table because not needed provide requesting.
