>&#13;     The following example issues a SELECT statement with a scalar function,
     RTRIM, that removes whitespace from the end of the column. Rather than
     creating an object with the properties "BREED" and "2", we use the AS
     clause in the SELECT statement to assign the name "name" to the modified
     column. The database server folds the column names to upper-case,
     resulting in an object with the properties "BREED" and "NAME".
