Applies a filter to the rows in the Table and obtains a new Table object.

Version Added: Outlook 2007

expression .Restrict(Filter)

expression A variable that represents a Table object.

Parameters

Name

Required/Optional

Data Type

Description

Filter

Required

String

Specifies the criteria for rows in the Table object.

Return Value

A Table object that is returned by applying Filter to the rows in the parent Table object.

You can only use Table.Restrict to apply another filter to that Table if the parent object of the Table is a Folder object. If the parent object is a Search object, Restrict will return an error.

Since the filter is applied to the rows in the Table object, this is equivalent to applying a filter that is a logical AND of Filter and all preceding filters applied to the same Table object.

Filter is a query on specified properties of items that are represented as rows in the parent Table. The query uses either the Microsoft Jet syntax or the DAV Searching and Locating (DASL) syntax. For example, the following Jet filter and DASL filter specify the same criteria for items with LastModificationTime earlier than 3:30pm of June 12, 2005:

criteria = "[LastModificationTime] < '" & Format$("6/12/2005 3:30PM","General Date") & "'"criteria = "@SQL=" & Chr(34) & "DAV:getlastmodified" & Chr(34) 
 & " < '" & Format$("6/12/2005 3:30PM","General Date") & "'" 

For more information on specifying filters for the Table object, see Filtering Items.

If Filter contains custom properties, those properties must exist in the parent folder of the Table object in order for the restriction to work correctly. Certain properties are not supported in a Table filter, including binary properties, computed properties, and HTML or RTF body content. For more information, see Unsupported Properties in a Table Object or Table Filter.

If Filter is a blank string, Restrict returns a Table object that is identical to the parent Table object.

The following code sample applies a Jet filter on items in the Inbox to obtain items with a LastModificationTime greater than November 1, 2005. It then prints the values of the default properties for these items in the Inbox: EntryID, Subject, CreationTime, LastModificationTime, and MessageClass.

Note Note

Since heterogeneous items can exist in the same folder in Outlook, the items returned from applying the filter to the Inbox may be of different types. In general, before accessing any properties that are not among the default properties for items in the Inbox, you should check the MessageClass of the item.

Sub RestrictTable() 
 'Declarations 
 Dim Filter As String 
 Dim oRow As Outlook.Row 
 Dim oTable As Outlook.Table 
 Dim oFolder As Outlook.Folder 
 
 'Get a Folder object for the Inbox 
 Set oFolder = Application.Session.GetDefaultFolder(olFolderInbox) 
 
 'Define Filter to obtain items last modified after November 1, 2005 
 Filter = "[LastModificationTime] > '11/1/2005'" 
 'Restrict with Filter 
 Set oTable = oFolder.GetTable(Filter) 
 
 'Enumerate the table using test for EndOfTable 
 Do Until (oTable.EndOfTable) 
 Set oRow = oTable.GetNextRow() 
 Debug.Print (oRow("EntryID")) 
 Debug.Print (oRow("Subject")) 
 Debug.Print (oRow("CreationTime")) 
 Debug.Print (oRow("LastModificationTime")) 
 Debug.Print (oRow("MessageClass")) 
 Loop 
End Sub
