Indicates whether changes can be made to a querydef object. If this property is TRUE, the querydef is updatable; otherwise, it isn't. Updatable means the querydef object's query definition can be changed. The Updatable property of a querydef object is set to TRUE if the query definition can be updated, even if the resulting recordset isn't updatable. To retrieve this property directly, call the querydef's [CanUpdate](../../mfc/reference/cdaoquerydef-class.md#canupdate) member function.

The number of seconds the Microsoft Jet database engine waits before a timeout error occurs when a query is run on an ODBC database. When you're using an ODBC database, such as Microsoft SQL Server, there may be delays because of network traffic or heavy use of the ODBC server. Rather than waiting indefinitely, you can specify how long the Microsoft Jet engine waits before it produces an error. The default timeout value is 60 seconds. You can retrieve the value of this property directly by calling the querydef's [GetODBCTimeout](../../mfc/reference/cdaoquerydef-class.md#getodbctimeout) member function. For more information, see the topic "ODBCTimeout Property" in DAO Help.

The querydef is an object of class [CDaoQueryDef](../../mfc/reference/cdaoquerydef-class.md). The references to Primary, Secondary, and All indicate how the information is returned by the [GetQueryDefInfo](../../mfc/reference/cdaodatabase-class.md#getquerydefinfo) member function in class `CDaoDatabase`.

Information retrieved by the [CDaoDatabase::GetQueryDefInfo](../../mfc/reference/cdaodatabase-class.md#getquerydefinfo) member function is stored in a `CDaoQueryDefInfo` structure. Call `GetQueryDefInfo` for the database object in whose QueryDefs collection the querydef object is stored. `CDaoQueryDefInfo` also defines a `Dump` member function in debug builds. You can use `Dump` to dump the contents of a `CDaoQueryDefInfo` object. Class `CDaoDatabase` also supplies member functions for directly accessing all of the properties returned in a `CDaoQueryDefInfo` object, so you'll seldom call `GetQueryDefInfo`.

When you append a new field or parameter object to the Fields or Parameters collection of a querydef object, an exception is thrown if the underlying database doesn't support the data type specified for the new object.
