RetriveMultiple not retrieving all the column values

(0) ShareShare

Posted on by Srini20 395

Hi,

I am trying to retrieve the data using RetrieveMultiple method. I am able to retrieve all the columns except one date time filed that one of our team mate created. Can you please confirm whether we need to apply any null conditions at the time of retrieving the data in case date field contains null values in system? If so how can we do that? I just wrote a simple straight forward query to retrieve the data I can see most of the columns except one date field that I need the value of.

QueryExpression qe = new QueryExpression();
qe.EntityName = "opportunity";
if (Columns == null)
qe.ColumnSet = new ColumnSet(true);
else
qe.ColumnSet = new ColumnSet(Columns);
qe.PageInfo.PagingCookie = "";
qe.PageInfo.PageNumber = PageNum;
qe.PageInfo.Count = 2500;
_service.RetrieveMultiple(qe);

    Thanks Madhan & Alex. My column already exist in column list and also I tried to query entire entity but couldn't find the columns related to null. I  just figured that column will not be in the result set if that contains null value.

    Thank you for quick response.

    Hi,

     as Madhan suggested, that column name might be missing from the Columns variable.

     Another alternative - even though you might be passing all column names to the columnSet, if the field is not, actually, populated, you won't find it in the attributes of the record. In other words,

     entity["new_fieldname"]

    will throw an exception if, for that particular record, new_fieldname attribute has not been populated. You can check if the attribute is there by calling entity.Contains("new_fieldname")

    Please add the list of columns to your query expression as shown below. 

       QueryExpression qe = new QueryExpression();

       qe.EntityName = "opportunity";

       if (Columns == null)

        qe.ColumnSet = new ColumnSet(true);

       qe.ColumnSet.Columns.Add("name");

        qe.ColumnSet.Columns.Add("nameofothercolumn1");

       qe.ColumnSet.Columns.Add("nameofothercolumn1");
