TFetchOption and TFetchOptions indicate the type of information about a record that a client dataset can request.
TFetchOption = ( foRecord, foBlobs, foDetails );
enum TFetchOption { foRecord, foBlobs, foDetails };
Providers encode the flags received from a client dataset that indicate what type of row information they require into a value of type TFetchOptions. This value is used internally when assembling the requested information. TFetchOptions is a set that includes zero or more of the following values:
Value |
Meaning |
foRecord |
The values of fields on the current record. (Used to refresh records). |
foBlobs |
The values of BLOB fields on the current record. (Used to implement delayed fetching of BLOB data). |
foDetails |
Any nested dataset fields for the current record. (Used to implement delayed fetching of detail datasets. |
