TPSQLDataset.Methods.GetIndexInfo

Top Previous Next

Retrieves information about the current index into the index data fields of the dataset.

Syntax:

procedure GetIndexInfo;

Description:

Call GetIndexInfo to update information about the current index. Ordinarily an application does not need to call GetIndexInfo because this routine is used internally to retrieve index information as needed. Some applications, however, may want to ensure that the index information used by the dataset is up-to-date.

GetIndexInfo queries for index information, including:

      • Whether or not the index is case insensitive.
      • The number of fields that make up the key for the index.
      • The field map for the index.
      • The size of the index key.
