SQLObjectList Object
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The SQLObjectList object is a fixed-membership container for objects enumerated by an object-listing method.

Methods
Remarks
SQL Distributed Management Objects (SQL-DMO) implements a number of container objects expressing, through their relationships, a logical structure for creating, viewing, and managing Microsoft SQL Server components. The SQL-DMO collection is one such container. The SQLObjectList object is another.
Collections, exposing the Add and Remove methods, implement SQL Server component management by mapping collection membership changes to component creation or deletion. The SQLObjectList object does not expose membership-modifying methods. Instead, applications create object lists to extract a subset of SQL Server components for viewing or management.
Unlike a collection, SQLObjectList does not guarantee that all objects contained have the same type. Some implemented lists, such as the list returned by the ListObjects method of the Database object, return a user-specified selection of objects. Use the TypeOf property of an object to check SQL-DMO object type when using lists of multiple kinds of objects.
In general, use the SQLObjectList object to get SQL-DMO objects that reference SQL Server components if an object-listing method is an appropriate mechanism. If the SQLObjectList object is not an appropriate container, such as when application logic is built to remove a SQL Server component, use the component referencing collection instead. The following Microsoft Visual Basic example illustrates removing the column binding for all rules in a database:
Dim oRule As SQLDMO.Rule
Dim oColumn As SQLDMO.Column
Dim oColList As SQLDMO.SQLObjectList
Dim oTable As SQLDMO.Table
For Each oRule In oCurDB.Rules
Set oColList = oRule.ListBoundColumns
For Each oColumn In oRule.ListBoundColumns
Set oTable = oColumn.Parent
oRule.UnbindFromColumn oTable.Name, oColumn.Name
Next oColumn
Next oRule
Note
For C/C++, Sqldmo.h defines a number of list object types. If an object listing method returns a SQLObjectList object whose members are identical, such as the ListPermissions method, the member function defines its return argument using the list object type
