URGENT!!{ System.QueryException: List has no rows for assignment to SObject }

if(trigger.isUpdate)
        {
            for(Lead_Contact_MDO_Mapping__c lcMap:trigger.new)
            {
                if(lcMap.Lead_Name__c != null)
                {
                    listMdoLead.add(lcMap);
                    mapLead.put(lcMap.Id, [select Id, PRG_Deduction_Amount__c, MDO_Price__c from Lead where Id =: lcMap.Lead_Name__c limit 1 ]);
                }
                if(lcMap.Contact_Name__c != null)
                {
                    listMdoContact.add(lcMap);
                    mapContact.put(lcMap.Id, [select Id, Total_MDO_Amount__c from Contact where Id =: lcMap.Contact_Name__c limit 1]);
                }
                mapMDO.put(lcMap.Id, [select Id, Quantity_In_Hand__c, MDO_Price__c, Unit_Assigned__c from MDO_Detail__c where Id =: lcMap.MDO_Name__c limit 1]);
            }

 

When I am trying to upload the trigger it is showing error that System.QueryException: List has no rows for assignment to SObject cause by this line

 

mapMDO.put(lcMap.Id, [select Id, Quantity_In_Hand__c, MDO_Price__c, Unit_Assigned__c from MDO_Detail__c where Id =: lcMap.MDO_Name__c limit 1]);

 

Can somebody tell me why am i getting this error? and how to resolve it?

Thanks in advance.:)

This means that the query [select Id, Quantity_In_Hand__c, MDO_Price__c, Unit_Assigned__c from MDO_Detail__c where Id =: lcMap.MDO_Name__c limit 1] is not returning any record. you need to modify the query so that it returns atleast one record.

Adding to previous reply, there are few other issues.

You have query in for loops

You have not bulkyfy your trigger
