Why empty cell throws an error during SQL stored procedure execution

Question

SELECT
    CAST ([content_html] AS XML).query(\'/root/Physicians/specialty/a\') AS [Specialty1]
    , CAST ([content_html] AS XML).query(\'/root/Physicians/specialty2/a\         


        

Answer 1

In case your problem is caused by NULL values, then you can solve your problem with sth like:

public string DisplayMultipleValues(object strValue)
{
   if (strValue == null)
      return "";
   else
      return (NonBlankValueOf(strValue.ToString()));
}

Your Eval statements should look like this:

<%# Eval("Specialty1") == null ? "" : Eval("Specialty1").ToString() + 
    DisplayMultipleValues(Eval("Specialty2")) + etc ...
