Examples

You must use an index when querying a table for records. An IndexCollection object provides the means to select an index by name, from either a table or a transactional repository:

Copy

Index idx = myTable.Indexes["myindex"];
Records[] records = idx.Query(...);

Copy

Index idx = myTransactionalRepository["myindex"];
Records[] records = idx.Query(...);

You can also use the IndexCollection.Names property to list all the indexes in a table (or repository).

Copy

// 
// the repository contains these indexes...
// 
IndexCollection ic = myTransactionalRepository.Indexes;
Console.WriteLine("From repository:");
foreach (String name in ic.Names) { Console.WriteLine("\t{0}", name); }

// 
// ...and the table contains these indexes
// 
ic = myTable.Indexes;
Console.WriteLine("From table:");
foreach (String name in ic.Names) { Console.WriteLine("\t{0}", name); }
