The methods of the Query class are listed below. For a complete list of Query class members, see the Query Members topic.
Public Static Methods
  FindObjectByPrimaryKey | Overloaded. Retrieves a persistable object by its primary key. |
| GetCount | Overloaded. Returns the total number of rows matching the given criteria, including duplicates and null values. Translates to a COUNT(*)query in SQL. |
Public Instance Methods
| Accept | Accepts the specified visitor. |
| AddPrefetch | Specifies how deep in the object graph this query will retrieve objects related to the target class. Multiple prefetches may be added to a single query. By retrieving all objects specified by relatedClassToPrefetch via a single SELECT statement to the database, prefetching avoids lazy loads of related objects and thus improves performance. |
| AddSelectField | Adds a field whose value will be returned by a DataSet. Only add select fields if you are retrieving values in a DataSet via a call to FindDataSet. |
| AddSelectFields | Adds to the set of fields whose values will be returned by a DataSet. Only add select fields if you are retrieving values in a DataSet via a call to FindDataSet. |
| BuildObjectGraphQuery | |
| Equals (inherited from Object) | Determines whether the specified Object is equal to the current Object. |
| GetClassesToRetrieve | Builds the complete set of Classes being retrieved by this query. |
| GetFullTableName | Get the fully qualified name of the table to which this object maps. |
| GetHashCode (inherited from Object) | Serves as a hash function for a particular type. GetHashCode is suitable for use in hashing algorithms and data structures like a hash table. |
| GetImmediateChildExpressions | Gets the child object model expressions that are directly contained by this expression. |
| GetInsertableFields | Get the set of insertable Fields to which this object, and any of its sub-types, maps. This is the set of ColumnFields that are populated by the middle tier when a row is inserted into the database. |
| GetNaturalIdentifier | Get a string that identifies this object to a person familiar with the object model. Used when an instance of this field is part of a logging or assertion statement. |
| GetRootTableMappedObject | Returns the root table mapped object in this query path; i.e., the starting point of this join path. |
| GetSelectableFields | Get the set of selectable Fields to which this object, and any of its sub-types, maps. |
| GetType (inherited from Object) | Gets the Type of the current instance. |
| GetUpdatableFields | Get the set of updatable ColumnFields to which this object, and any of its sub-types, maps. This list would exclude, for example, any primary key columns. |
| HasAnyComputedPrimaryKeyColumns | Determines whether this table mapped object has any computed primary key columns. |
| IsCount | Determines whether this instance represents a SQL COUNT statement. |
| ToString (inherited from Object) | Returns a String that represents the current Object. |
