System.QueryException: List has no rows for assignment to SObject

Usually we will come across this type issue in many places and in many situations also .In the same way I have come across the same issue in one of the my class and I have done some work around it to fix this issue.I will explain this one with an example which may brings you an complete understanding about the issue.

Scenario:
I have 3 objects called Time_Track__c,Expert__c and User.Expert__c and User having a lookup relationship where User (Sforce_User__c) is acting as parent for Expert object and Time_Track__c and Expert__c also having lookup relationship where Time_Track__c is acting as child for Expert (Expert_Name__c) object .I have an visual force page which is using Time_Track__c  as a Standard Controller and I am having some extension class on same page .In the constructor of the extension class I am trying to query on Expert__c object based on logged in user to assign this expert to new time track as shown below

Source Code:
public class TrackExtn {
  public Time_Track__c timeTrack{get;set;} 

  public TrackExtn(ApexPages.StandardController controller) {
    timeTrack = new Time_Track__c();        
    timeTrack= (Time_Track__c)controller.getRecord();
       
    if(controller.getId()==null)
    {
       Expert__c exp = new Expert__c();
       //In below line you will receive List has no rows for assignment to SObject
       exp = [Select id from Expert__c where Sforce_User__c=:UserInfo.getUserId() limit 1];
       timeTrack.Expert_Name__c = exp!=null?exp.id:null;
           
    }

    }
}

Error:

When you execute the above code at run time if your having at least one matching Expert__c record for logged in user it will work very smoothly .If there is no matching Expert__c record for logged in user will end up with System.QueryException: List has no rows for assignment to SObject . Even if the matching record is not there it should continue fir the next lines with out throwing any error but here it's failing and terminating the complete execution. To handle this we need to follow below work around solution.


Workaround Solution:

We need to convert the Query result holder from SObject type to List<SObject> type that will resolve the issue .Please look at the below code for the work around solution

public class TrackExtn {
  public Time_Track__c timeTrack{get;set;} 

  public TrackExtn(ApexPages.StandardController controller) {
    timeTrack = new Time_Track__c();        
    timeTrack= (Time_Track__c)controller.getRecord();
      
    if(controller.getId()==null)
    {
        //Convert Sobject type to List<Sobject> type to store query result
        List<Expert__c> listexp =new List<Expert__c>();
        listexp = [Select id from Expert__c where Sforce_User__c =:UserInfo.getUserId() limit 1];
        System.debug('loggedinTech ..'+listexp );
        td.Technician__c = listexp.isEmpty()?null:listexp[0].id;
           
    }

    }
}

System.QueryException: Only variable references are allowed in dynamic SOQL/SOSL.

Error:

Whenever your working with Dynamic SOQL construction you should be very careful regarding the Single Quotes(',') or Open/Close parentheses'(' ')'  and bind variables(':') in query string.If your also getting the same error as mentioned above please refer below code.

Source Code:

public void fetchOrders()
{
List<Order__c> listOrders = new List<Order__c>();
String selWOStatus ='Test'  // Usually value for this comes from visual force page

String q ='SELECT Id, Name, Location__c,End_Date__c,Createddate FROM Order__c where 
           Location__r.OwnerId=:'+UserInfo.getUserId();
                        
if('All'.equalsIgnoreCase(selWOStatus))
  q + = ' AND (Createddate =LAST_N_MONTHS:6 OR End_Date__c < NEXT_N_MONTHS:6) LIMIT 1000'; 

else
  q + =' AND (Status =\''+String.escapeSingleQuotes(selWOStatus)+'\' 
         AND Createddate = LAST_N_MONTHS:6) LIMIT 1000';

System.debug('q....'+q); 

listOrders  = Database.query(q);

System.debug('listTSOOrders....'+listOrders);

}

When you run this above code at run time you will end up with System.QueryException: Only variable references are allowed in dynamic SOQL/SOSL .This is due to the (':') bind variable usage in dynamic query construction which will cause the error and that causes missing a single quote for logged in user ID as shown query string coming at run time as shown below

Actual Query String at Run time:

'SELECT Id, Name, Location__c,End_Date__c,Createddate 
FROM Order__c 
where Location__r.OwnerId=:00560000004LFQkAAO 
AND (Status ='Test' AND Createddate = LAST_N_MONTHS:6) LIMIT 1000';

Excepted Query String at Run time:


'SELECT Id, Name, Location__c,End_Date__c,Createddate 
FROM Order__c 
where Location__r.OwnerId='00560000004LFQkAAO'
AND (Status ='Test' AND Createddate = LAST_N_MONTHS:6) LIMIT 1000';


Work Around Solution
Remove bind variable from query string and add single quotes before and after the user id

public void fetchOrders()
{
List<Order__c> listOrders = new List<Order__c>();
String selWOStatus ='Test'  // Usually value for this comes from visual force page

String qry ='SELECT Id, Name, Location__c,End_Date__c,Createddate FROM Order__c where 
           Location__r.OwnerId=\''+UserInfo.getUserId()+'\'';
                        
if('All'.equalsIgnoreCase(selWOStatus))
  qry + = ' AND (Createddate =LAST_N_MONTHS:6 OR End_Date__c < NEXT_N_MONTHS:6) LIMIT 1000'; 

else
  qry + =' AND (Status =\''+String.escapeSingleQuotes(selWOStatus)+'\' 
         AND Createddate = LAST_N_MONTHS:6) LIMIT 1000';

System.debug('qry....'+qry); 

listOrders  = Database.query(qry);

System.debug('listTSOOrders....'+listOrders);

How To Fetch Next 6 Months or Last 6 Months Records From Salesforce

If your trying to fetch records from Salesforce based on some date values likes today ,tomorrow,last few days/months/weeks/years or next few days/months/weeks/years we can make use of the Salesforce Date Literals to simplify the SOQL query as much as possible and each literal is a range of time beginning with midnight (12:00:00).

public void fetchOrders()
{
List<Order__c> listOrders = new List<Order__c>();
String selWOStatus ='Test'  // Usually value for this comes from visual force page

String qry ='SELECT Id, Name, Location__c,End_Date__c,Createddate FROM Order__c where 
           Location__r.OwnerId=\''+UserInfo.getUserId()+'\'';
                        
if('All'.equalsIgnoreCase(selWOStatus))
  qry +=' AND (Createddate =LAST_N_MONTHS:6 OR End_Date__c < NEXT_N_MONTHS:6) LIMIT 1000';
  
else if('Open'.equalsIgnoreCase(selWOStatus))
  qry +=' AND (End_Date__c < NEXT_N_MONTHS:6 AND (Status !=\'Closed\' AND 
         Status !=\'Canceled\' AND Status !=\'Converted\')) LIMIT 1000';
    
else
  qry +=' AND (Status =\''+String.escapeSingleQuotes(selWOStatus)+'\' 
         AND Createddate = LAST_N_MONTHS:6) LIMIT 1000';

System.debug('q....'+qry); 

listOrders  = Database.query(qry);

System.StringException: Invalid id Error in Salesforce

Usually this kind of error we will be receiving in test classes.This is due to when your working with any kind of relationship fields in objects.Let me explain with an example below

Error:

We have a two objects called Order__c and Time__c and these two objects are having a lookup relationship where Order__c is Child and Time__c is a parent.Now i have to create a test record for Time__c along with Order__c and then I want to update Time__c record Order__c with null value.
@isTest 
private class TestTimeEntry {
    static testMethod void validateTime() {
        Order__c ord = new Order__c();
        ord.Name ='Test Order';
        insert ord;
        
        Time__c tm1 = new Time__c();
        tm1.Order__c = ord.id;
        tm1.name = 'test time';
        insert tm1;
        
        Time__c tm2 =[Select id,name,Order__c from Time__c where id=:tm1.id];
        tm2.Order__c =''; //At runtime we will receive Error here
        update tm2;
    }
}

Root Cause:

So when you run this test class you will receive a runtime error called System.StringException: Invalid id  at an update statement due to assigning an empty string(empty space) to Order__c.Usually all relationship fields will accepts Ids or null key word. 

Work Around Solution
So when your trying to assign an empty value for relationship field we have to specify null keyword instead of an empty space('')
@isTest 
private class TestTimeEntry {
    static testMethod void validateTime() {
        Order__c ord = new Order__c();
        ord.Name ='Test Order';
        insert ord;
        
        Time__c tm1 = new Time__c();
        tm1.Order__c = ord.id;
        tm1.name = 'test time';
        insert tm1;
        
        Time__c tm2 =[Select id,name,Order__c from Time__c where id=:tm1.id];
        tm2.Order__c =null; //An empty space replaced with null keyword
        update tm2;
    }
}

When you try to login into sandbox from June 25 ,2016 on wards and if you end of  with an error called Stronger security is required, don't worry please read the below instructions to resolve it


Root Causes

This is due to the below reasons

  • As per the salesforce notifications they will stop supporting TLS 1.0 and automatically all sandboxes will be upgraded to TLS 1.1 from June 25,2016 .
  • All the production orgs will be upgraded to TLS 1.1 from March 4,2017.

How To Write a SOQL To Fetch All Events Related to Account and Opportunity

Scenario:

Usually when we are writing any kind of SOQL queries on related objects we always known that this particular child record always be linked to specified parent object record. For example if you have a relationship between Account(Parent) and Contact(child) that means every contact record is related any one the account record not to any ABC__c or BCD__c objects.

But where in case of Task or Events if you could see we can't guarantee that these Tasks or Events are always related to a Account records or Contact Records because these Task or Events can be linked to any one of the Contract,Campaign,Account,Opportunity,Product,Asset,Case,Solution,Quote and Any Custom Objects .

Question:
In such type of situations the Task or Event that is linked to which object it's not a static and it's gets varies based on the Event that your creating for which object(Called as Polymorphic Relationship).Now If you want to fetch all Events related to Account and Opportunity only.How we need to write a SOQL query ?



Solution:

We already know that WhatId filed in Event or Task for deciding for which object this is linked /created.So with the help of TYPE qualifier on WhatId we can achieve this.The TYPE qualifier on field always determine the object type that is referenced for Task or Event.Use this TYPE clause on where condition of SOQL to control the result.

SELECT Id,subject,What.Type,whatId 
FROM Event
WHERE What.Type IN ('Account', 'Opportunity')

This above SOQL query returns all the Events related to Account and Opportunity only.


You can also apply comparison operators such as '=' or LIKE on WHERE condition of TYPE clause .


[SELECT Id,subject,What.Type,whatId 
FROM Event
WHERE What.Type like '%Accou%']

[SELECT Id,subject,What.Type,whatId 
FROM Event
WHERE What.Type ='Position__c']

They are multiple other ways also to do same.So we will discuss all those things in my next post.

Thanks for visiting...Enjoy!!!


What is Polymorphic Relationship in Salesforce ?

We are all very familiar with relationships in Salesforce right? Usually when we are discussing about relationships in salesforce immediately in our mind below listed relationship will appears

  • Lookup Relation Ship (Many-One relationship)
  • Master-detail Relationship  (Many-One relationship)
  • Many-to-Many Relationship
  • Self Relation Ship
But apart from this in salesforce we have one more relationship called Polymorphic Relationship.In all the above relationship (except Polymorphic Relationship) we always know that this particular child record always be linked to specified parent object record. For example if you have a relationship between Account(Parent) and Contact(child) that means every contact record is related any one the account record not to any ABC__c or BCD__c objects.

But where in case of Task or Events if you could see we can't guarantee that these Tasks or Events are always related to a Account records or Contact Records because these Task or Events can be linked to any one of the Contract,Campaign,Account,Opportunity,Product,Asset,Case,Solution,Quote and Any Custom Objects .These types of relationships is called as Polymorphic Relationship.In Polymorphic Relationship the referenced object of relationship can be any one of the Standard or Custom Objects.

Linking an attachment to any one of the custom object or standard object with the help of the Parent Id also refereed as Polymorphic Relationship only.

When your working with Polymorphic Relationship objects in SOQL we have several ways to access.

Follow my next to post to learn how to use this Polymorphic Relationship in SOQL.

Issue with action support function on select of select list values

Today we had an issue with selection of pick-list. I am just trying to invoke a controller method when a user selects a pick list value from drop down and we are using an <apex:actionSupport> to make a call to the controller and the event is onchnage on onselect but unfortunately we are not able to make a call to controller method and the actionsupport with onselect or onchange in not working along with rerender also.



After a multiple hours of surfing over the internet we got some suggestion that just replace the onselect or onchnage with onclick event then it is started working and then after again reverted back to onselect or onchange now I'm able to make a call to controller method .I am not sure why is it working like that.

If you people are also facing the same issue just replace the your event onselect or onchange with onclick and try to invoke a controller method and if it's able to make a call to controller then again revert the onclick with onselect or onchange.

INVALID_FIELD_FOR_INSERT_UPDATE, Account: bad field names on insert/update call: Name: [Name]

When your working with Person Accounts in Salesforce we should be very careful because these Accounts can also acts as a Contact .It means these person accounts will share many fields with contacts.

The Person Account name will contains First Name and Last Name .When your trying to load any Person Accounts with data loader or with any other apex code we should follow some naming conventions .If your trying to map these field values to Name field of Account we will end up with the same error.

So when your loading the Person Accounts data your .csv file must contain a columns FirstName and LastName but not only the Name.
