Здравствуйте!
Есть код, который будет повторяться много раз. В нем изменяется только имя таблицы adotable. Как оформить его в процедуру с параметром имени таблицы?

[Yurk@]

Код:

procedure TableOperations(FTableName : string);
begin
  ADOTable.Close;
  ADOTable.TableName := FTableName;
  // и т.д.
  // и т.п.
end;

[Aristarh Dark]

Ну если реально "имя таблицы", то:

Код:

procedure SomeProc(ATableName:string)
begin
...
end;

а если объект-таблица, то:

Код:

procedure SomeProc(ADOTable:TADOTable)
begin
...
end;

[Mrak]

вот с кодом понятней будет
впервые пользую процедуры, вроде все верно по объявлению-описанию-вызову

Код:

type // объявляю
  TForm8 = class(TForm)
    // .....
    procedure af8(table_name: string); // ну явно не стринг, TADOTable нет
var
  Form8: TForm8;

implementation
{$R *.dfm}

uses Unit1, Unit_DM;

procedure af8(table_name: ??string); // описываю
begin
   if dm.table_name.fieldbyname('zayavka').asstring = 'Заявка' then
   btn1.visible:=true;
end;

procedure TForm8.Button1Click(Sender: TObject); // вызываю
begin
  af8(adotable_klient);
end;

Если использовать именно в таком контексте, то:

Код:

type // объявляю
  TForm8 = class(TForm)
    // .....
    procedure af8(table: TDataSet); // ну явно не стринг, TADOTable нет
var
  Form8: TForm8;
 
implementation
{$R *.dfm}
 
uses Unit1, Unit_DM;
 
procedure af8(table: TDataSet); // описываю
begin
   if table.fieldbyname('zayavka').asstring = 'Заявка' then
   btn1.visible:=true;
end;
 
procedure TForm8.Button1Click(Sender: TObject); // вызываю
begin
  af8(dm.table_name);
end;

Aristarh Dark, нет такого типа tdataset

Да ну, а я то как лох им пользуюсь с прошлого века:

[edit] Description

TDataSet is the base class for all dataset components that represent data in rows and columns.




TDataSet introduces the basic properties, events, and methods for working with data.

Many of these properties, events, and methods are abstract (Delphi) or pure virtual (C++) in TDataSet. Abstract or pure virtual declarations are declarations without implementations. At the TDataSet level they cannot be used or accessed. Developers must use or derive descendants of TDataSet that redeclare and implement these abstract or pure virtual methods. Many of the other TDataSet methods are declared and implemented in TDataSet as virtual methods, but the implementations are merely stubs that are reimplemented in descendants.

TDataSet has two several descendants: TCustomADODataSet, TIBCustomDataSet, TCustomSQLDataSet, TCustomClientDataSet and TWideDataSet.

TBDEDataSet is the base class for datasets that access their data using the Borland Database Engine (BDE). TBDEDataSet descendants include TTable, TQuery, and TStoredProc. Developers who create custom dataset components that use the BDE derive them from TBDEDataSet, TDBDataSet, TQuery, TStoredProc, or TTable.

TCustomADODataSet is the base class for datasets that access their data using ActiveX Data Objects (ADO). TCustomADODataSet descendants include TADODataSet, TADOTable, TADOQuery, and TADOStoredProc. Developers who create custom dataset components that use ADO derive them from CustomADODataSet.

TIBCustomDataSet is the base class for datasets that directly access the data in InterBase tables. TIBCustomDataSet descendants include TIBDataSet, TIBTable, TIBQuery, and TIBStoredProc. Developers who create custom dataset components that directly access data in an InterBase database derive from TIBCustomDataSet.

TCustomSQLDataSet is the base class for unidirectional datasets. Unidirectional datasets are read-only datasets that permit only forward navigation. TCustomSQLDataSet descendants include the dbExpress datasets TSQLDataSet, TSQLQuery, TSQLTable, and TSQLStoredProc. Developers who create custom dataset components that use dbExpress to access their data derive from TCustomSQLDataSet.

TCustomClientDataSet is the base class for in-memory datasets. Client datasets can work with data from files on disk or with data provided by another component via a provider. They cache that data in memory, maintain a record of any changes in a change log, and apply cached updates at a later point back to the source of the data. Developers who create custom datasets that store their data in an in-memory cache derive from TCustomClientDataSet.

TWideDataSet provides dataset support for wide strings.

Developer's can also derive custom dataset components directly from TDataSet, providing their own mechanisms for accessing and manipulating the data.
