修改完成状态(类写法)

1，定义批量修改完成状态类

unit UUpdateWanChengState;

interface
uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.ComCtrls, Data.DB, Data.Win.ADODB,
  Vcl.ExtCtrls, Vcl.DBCtrls, Vcl.Grids, Vcl.DBGrids, Clipbrd, Vcl.Menus,
  Vcl.StdCtrls, DBGridEhGrouping, ToolCtrlsEh, DBGridEhToolCtrls, DynVarsEh,
  EhLibVCL, GridsEh, DBAxisGridsEh, DBGridEh,EhLibADO,DBGridEhImpExp;

  /// <summary>
  /// 定义右键批量修改完成状态类
  /// </summary>
type TUpdateWanChengState=class
  public
  class procedure updatewanchengstate(const SValue: string; var SAdq: TADOQuery);
end;

implementation

uses FDataPool, 日常管理助手;
class procedure TUpdateWanChengState.updatewanchengstate(const SValue: string;var SAdq: TADOQuery);
var
SAdoq:TADOQuery;
SBiao: string;
begin
try
SAdoq:=TADOQuery.Create(nil);
SAdoq.Connection:=frmDataPool.ADOConnection1;
SBiao:=copy(SAdq.name,4,length(SAdq.name)-3);
 with SAdoq do
 begin
  close;
  SQL.Text:='UPDATE '+SBiao+' SET 状态 = '+SValue.QuotedString+' WHERE 选中 = true';
  ExecSQL;
 end;
 //防止程序假死
 Application.ProcessMessages;
 //刷新纪录
 SAdq.Requery();
finally
  SAdoq.Free;
end;
end;

end.

2，类引用实现应用：

注意记得添加需要引用的类的单元名UUpdateWanChengState

procedure TForm3.N25Click(Sender: TObject);
begin
//右击批量修改完成状态为未开始
  TUpdateWanChengState.updatewanchengstate('未开始',frmDataPool.qry需要做的事);
end;


procedure TForm3.N26Click(Sender: TObject);
begin
//右击批量修改完成状态为正在进行
  TUpdateWanChengState.updatewanchengstate('正在进行',frmDataPool.qry需要做的事);
end;

procedure TForm3.N27Click(Sender: TObject);
begin
//右击批量修改完成状态为已完成
  TUpdateWanChengState.updatewanchengstate('已完成',frmDataPool.qry需要做的事);
end;

procedure TForm3.N28Click(Sender: TObject);
begin
//右击批量修改完成状态为已延期
  TUpdateWanChengState.updatewanchengstate('已延期',frmDataPool.qry需要做的事);
end;
