TFieldDef.Create Constructor
|
RAD Studio VCL Reference
|
|
|
Creates and initializes a TFieldDef instance.
constructor Create(Owner: TFieldDefs; const Name: WideString; DataType: TFieldType; Size: Integer; Required: Boolean; FieldNo: Integer); overload; reintroduce;
__fastcall TFieldDef(TFieldDefs Owner, const BSTR Name, TFieldType DataType, int Size, Boolean Required, int FieldNo);
Applications should not call Create directly. A TFieldDef is created automatically by the dataset for each field in an already existing table. When composing field definitions preparatory to creating a new dataset, the TFieldDefs.AddFieldDef method (or the older TFieldDefs.Add method) creates the needed instance of TFieldDef.
