FieldNumbers Property
Applies To
Declaration
property FieldNumbers: TStrings;
Description
This is a list of field numbers representing the fields to be retrieved by the data access component.
The default value of this property is a single array item set to ".01". Set each item in this TStrings array to a field number that should be retrieved. When a server call is made, all items in the array are concatenated into a single Fields parameter to pass to the data access component's underlying DBS call.
You can set array items in the FieldNumbers array in the following formats:
| Item Format | Applies To | Example |
|---|---|---|
| Individual field | All | .01 |
| DR-style list | All | .01;2;3;5 |
| DR-style range | TFMGets only | .01:5 |
For the TFMGets component, to set this property at run-time, use the AddField and RemoveField methods. For TFMFinder and TFMLister components, use TStrings methods to set this property at run-time.
