MyCode代碼生成器，自動生成BCB版數(shù)據(jù)庫操作代碼(ADO)，無需手工編寫，只需簡單調(diào)用就可以進行繁瑣的數(shù)據(jù)庫操作。

調(diào)用方法

準備工作：

登錄數(shù)據(jù)庫，點擊生成，將DBComm文件夾復制到使用程序目錄，在cpp文件頭添加如下:

#include ".\DBComm\DBTables\MyInfoOperator.h"

#include ".\DBComm\DBTables\RecordOperator.h"

#include ".\DBComm\DBTables\RecordViewOperator.h"

#include ".\DBComm\DBComm.h"

點擊“工程”菜單，選擇“添加到工程”，將DBComm內(nèi)所有cpp文件添加(包含DBTables下cpp文件)

調(diào)用示例

連接數(shù)據(jù)庫

void __fastcall TForm1::FormCreate(TObject *Sender)

{

WideString wstrConnStr="Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=mytest";

if(DBComm::Instance().ConnectDB(wstrConnStr))

{

DBGrid1->DataSource=DBComm::Instance().Tables(DBComm::RecordView)->Source();

}

}

新增一條記錄

void __fastcall TForm1::SpeedButton1Click(TObject *Sender)

{

DBComm::Instance().Tables(DBComm::MyInfo)->New(LabeledEdit2->Text,LabeledEdit3->Text.ToDouble(),"admin",Now());

}

}

刪除一條記錄

void __fastcall TForm1::SpeedButton3Click(TObject *Sender)

{

if(DBGrid1->DataSource->DataSet->RecordCount)

{

int nID=DBGrid1->DataSource->DataSet->Fields->Fields[0]->AsInteger;

String strCondition="ID="+String(nID);

DBComm::Instance().Tables(DBComm::Record)->Delete(strCondition);

}

}

更新一條記錄

void __fastcall TForm1::SpeedButton2Click(TObject *Sender)

{

if(DBGrid1->DataSource->DataSet->RecordCount)

{

int nID=DBGrid1->DataSource->DataSet->Fields->Fields[1]->AsInteger;

String strName=LabeledEdit2->Text;

float fMoney=LabeledEdit3->Text.ToDouble();

String strCondition="ID="+String(nID);

DBComm::Instance().Tables(DBComm::MyInfo)->Update(strName,fMoney,"admin",Now(),strCondition);

}

}

獲取數(shù)據(jù)源

DBGrid1->DataSource=DBComm::Instance().Tables(DBComm::RecordView)->Source();
