BUG in SOQL? Invalid SOQL to get Task Owner information

I am trying to get Task Owner's Mobile Phone number using the following SOQL:

 

Select  t.Owner.MobilePhone from Task t

 

When I try to execute it I get an error message:  "No such column 'MobilePhone' on entity 'Name'"

 

The error shows up for some other columns too, e.g. CallCenterId (of User object), while some I am able to get data for some other columns, such as Name, LastName, etc.

 

Why is that?

Owner on Task is a polymorphic relationship (i.e. to can be a foreign key to different types), for these types of relationships only a subset of data of the related object is exposed, these are fields defined on the Name entity, including firstName, lastName & phone, but not all fields from user. From the schema you can see this because the ownerId field has the isNamePointing property set to true. There's also a give-away in the error message where it says the field is not valid for the Name entity. This is all covered in the SOQL-R section of the API documentation.

It normally works from apex or VF Class. i am not sure check out. but it definitely not works from apex explorer or salesforce

schema in eclipse

I tried it yesterday in the schema in Eclipse and was getting the same issue.

The query doesn't work both in Apex and through API.

Try this:

 

Select t.Owner.Phone  From Task t

 

 

Thanks

The thing is that there are 2 fields on User object: Phone and MobilePhone.

I need MobilePhone.

Oops...No luck for me too

 

I could see the field "Cell" (for Mobile phone), but query does not work.

Ron, thanks for looking into this. What you're saying makes sense, but there are couple of things I don't undertand:

1. Phone and MobilePhone fields have exactly the same attributes:

- createable

- filterable

- nillable

- updateable

 

... and the following SOQL works:

Select  t.Owner.Phone from Task t

 

that is Phone is queryable

 

2.Some other fields, such as 'Name', 'LastName' having the following attributes:

- filterable

- sortable

 

are still queryable with SOQL queries, such as:

Select t.Owner.Name from Task t 

 

 

 

3. Side question - not really for you, but still - why would Apex Explorer and Schema browser in the IDE let a user create invalid SOQL statements?

 

 

Thanks,

Shamil

hey shamil,

did you resolve this?

Since this info cannot be obtained in 1 SOQL call, you'll need to make a separate SOQL request to objects that can be Task Owners

yes I got it afterwords I did it same way you are suggesting...
