FrankF Single Query to join Cmapaign and CampaignMember?
What I would like to do is get a list of Campaign Names for a given Lead.
I can do this via 2 soql queries -
campaignids = [select CampaignId from CampaignMember where LeadId='00Q7000000XXXXX]
and then
campaignNames= [select Name from Campaign where Id in :campaignids]
is there a way to do this in one query?
I've tried select Name from Campaign where CampaignMembers__r.LeadId = '00Q7000000XXXXX'since I see that Campaign has a child relationship with CampaignMember but that doesn't seem to work.
Any help would be much appreciated.
Frank.
Are you concerned about governor limits? I believe nested queries only count as 1 soql query:
Id LeadId = '00Q7000000XXXXX'; List<String> CampaignNames=[SELECT Name FROM Campaign WHERE Id IN [SELECT CampaignID FROM CampaignMember WHERE LeadId =: leadId]];
You might have to add ".Name" just after the "]]" (ie- "...leadId]].Name" to get this to work as a string list.
<I deleted my bad syntax post & replaced with the below>
Here's my "revised" example. Note you can only assign the query to an sObject CampaignMember:
List<CampaignMember> CampaignNames = [SELECT Campaign.Name FROM CampaignMember WHERE LeadID =:leadId]; for(CampaignMember cm: CampaignNames){ system.debug('Campaign Name: '+cm.Campaign.Name); }
Note the syntax to get the name is CampaignMember.Campaign.Name
The difference between this approach & my previous post is that this one will have duplicate Campaigns in there if you have more filter on more than 1 lead ID wherease my previous example will not have duplicate Campaigns (and their names) if 2 leads are in the same campaign.
Couple of typos in there, it should read:
List<String> CampaignNames=[SELECT Campaign.Name FROM CampaignMember WHERE LeadId=:leadId];
