deryckj System.QueryException: List has more than 1 row for assignment to SObject
Class.Lead_Creation.populateAdvertizingInfo: line 88, column 1
---------------------------------
Error results on VisualForce page that references the following code on my visualforce page. What's highlighted in orange is what is failing and the referenced code follows below:
<apex:selectListvalue="{!SelectedExtension}"size="1"label="Ad Series"id="extension">
<apex:selectOptionsvalue="{!ExtensionsOptions}"></apex:selectOptions>
<apex:actionSupportevent="onchange"action="{!populateAdvertizingInfo}"reRender="leadInterest"/>
</apex:selectList>
1 private Campaign thisCampaign ;
2 public void populateAdvertizingInfo()
3 {
4 List<String> SelectedAdSeries = SelectedExtension.split('-');
5 Decimal ext = Decimal.valueof(SelectedAdSeries[1]);
6 thisCampaign = [Select Campaign_Fully_Qualified__c, Ad_Type__c, Ad_Size__c, Media_Source__c, Project_Code__c,
7 Type from Campaign where Project__c =: currentLead.Project_site__c AND Extension__c =: ext];
8 system.debug('the campaign '+thisCampaign.id);
9 currentLead.Ad_Type__c = thisCampaign.Ad_Type__c;
10 currentLead.Ad_Size__c = thisCampaign.Ad_Size__c;
11 currentLead.Media_Source__c = thisCampaign.Media_Source__c;
12 currentLead.Project_Code__c = thisCampaign.Project_Code__c;
13 currentLead.Ad_Series__c = thisCampaign.Campaign_Fully_Qualified__c;
14 SelectedCampaignID = thisCampaign.Id;
15 SelectedCampaignName = thisCampaign.Campaign_Fully_Qualified__c;
16 }
It appears that I am getting hung up on the line 6 above. Any suggestions?
Your SOQL query is returning more than one result. You have a few options here:
1) You could cast it to a list instead of a single record.
2) You could add LIMIT 1 to your SOQL query to return only 1 record.
3) You could search by more filtered criteria to only return 1 result

Tim, thank you very much. I know this was an elementary question. I am new to this environment. The option of adding a limit of 1 was exactly what I needed!
No problem. One thing to keep in mind, your query was returning more than one result. Adding the LIMIT 1 does not neccessarily mean your are selecting the correct result. You might want to consider filtering additionally or adding a ORDER BY to ensure you are selecting the correct record.
