ITableData : IUnknown

Applies to: Office 2010 | Outlook 2010 | Visual Studio

Provides utility methods for working with tables. MAPI provides table data objects or objects that implement ITableData to help service providers perform table maintenance. To obtain a table data object, service providers call the CreateTable function.

Vtable Order

HrGetView	Creates a table view, returning a pointer to an IMAPITable implementation.
HrModifyRow	Inserts a new table row, possibly replacing an existing row.
HrDeleteRow	Deletes a table row.
HrQueryRow	Retrieves a table row.
HrEnumRow	Retrieves a row based on its position in the table.
HrNotify	Sends a notification for a table row.
HrInsertRow	Inserts a table row.
HrModifyRows	Inserts multiple table rows, possibly replacing existing rows.
HrDeleteRows	Deletes multiple table rows.

Remarks

The MAPI implementation of ITableData works with tables by holding all of the data and any associated restrictions in memory, making it unsuitable for use with very large tables. Large restrictions and complex operations such as categorization are not supported.

Table data objects identify rows by using an index column, a property that is guaranteed to have a unique value for each row. Most service providers use the PR_INSTANCE_KEY (PidTagInstanceKey) property as the index column. Properties that have multiple values cannot be used as an index column.

Table data objects generate a single notification regardless of the number of rows affected by a change or deletion. If a target row in an operation does not exist, a row is added.
