Description
Reports the size associated with the field in the physical database table.
Use Size to determine the size associated with the corresponding physical field.
Size is meaningful only for a field definition object with one of the following TFieldType values: ftString, ftBCD, ftBytes, ftVarBytes, ftBlob, ftMemo or ftGraphic. For string and byte fields, Size is the number of bytes reserved in the table for the field. For a BCD field, Size is the number of digits following the decimal point. For a BLOB, memo, or graphic field, Size is the number of bytes from the field's value that are stored in the actual database table.
