property FieldNo: Integer;
Beschreibung
Use FieldNo to find out where the physical field the field definition references is in the set of fields in the table. For example, if the value of FieldNo is 2, then the field is the second field in the table.
When adding field definitions to a data set, set FieldNo to specify the location at which the field will be created.
The difference between FieldNo and InitialFieldNo is, that InitialFieldNo reflects the current state of the underlying database table while FieldNo holds the number of the field after the next call to CreateTable or AlterTable.
