Description

Use the properties and methods of an index definition to:

Set the attributes of a new index in a table created with TTable . :: CreateTable or TClientDataSet. ::CreateDataSet.

Determine the name of an index.

Identify the fields that make up the index, or the dBASE expression that orders the index.

Determine the characteristics of the index.

Note: you cannot use TIndexDef objects in a dataset component's IndexDefs property to add indexes to already existing tables. To do that, use methods such as TTable

. :: AddIndex and TClientDataSet. ::AddIndex.
