修改完成比例
方法1:独立事件单独写法
procedure TForm3.N21Click(Sender: TObject);
var
BiLi:string;
SAdoq:TADOQuery;
begin
SAdoq:=TADOQuery.Create(nil);
SAdoq.Connection:=frmDataPool.ADOConnection1;
try
//或许比例数值
if not InputQuery('输入比例', '请输入比例值', BiLi) then
begin
ShowMessage('请输入完成比例值');
Exit;
end;
with SAdoq do
begin
Close;
SQL.Text:='UPDATE 需要做的事 SET 已完成百分比 ='+BiLi.QuotedString+'WHERE 选中 = true';
ExecSQL;
end;
//防止程序假死
Application.ProcessMessages;
//刷新纪录显示
frmDataPool.qry需要做的事.Close;
frmDataPool.qry需要做的事.Open;
finally
SAdoq.Free;
end;
end;
方法2:类写法
unit UUpdateBiLi;
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;
type TUpdateBiLi=class
public
class procedure selectedupdatebili (var SAdq:TADOQuery);
end;
implementation
uses FDataPool;
class procedure TUpdateBiLi.selectedupdatebili(var SAdq: TADOQuery);
var
BiLi,SBiao: string;
SAdoq:TADOQuery;
begin
SAdoq:=TADOQuery.Create(nil);
SAdoq.Connection:=frmDataPool.ADOConnection1;
SBiao:=copy(SAdq.name,4,length(SAdq.name)-3);
try
//或许比例数值
if not InputQuery('输入比例', '请输入比例值', BiLi) then
begin
ShowMessage('请输入完成比例值');
Exit;
end;
with SAdoq do
begin
Close;
SQL.Text:='UPDATE '+SBiao+' SET 已完成百分比 ='+BiLi.QuotedString+'WHERE 选中 = true';
ExecSQL;
end;
//防止程序假死
Application.ProcessMessages;
//刷新纪录显示
SAdq.Requery();
finally
SAdoq.Free;
end;
end;
end.
类引用,记住在use里面添加引用类单元的名字UUpdateBiLi
procedure TForm3.N21Click(Sender: TObject);
begin
//批量修改选中记录的完成比例
TUpdateBiLi.selectedupdatebili(frmDataPool.qry需要做的事);
end;
