Remarks

The ColumnSet class is used with methods and messages that retrieve one or more records from the database. The query returns non-null values for the attributes that are contained in the Columns property. The attributes not included in the ColumnSet will contain null values. If the column set includes attributes that are not valid for retrieve, they will be ignored and no values will be returned for those attributes.

The primary key is always returned and contains a non-null value.

Attributes are specified by name. For more information, see SchemaName.
