调用措施

豫备使命：

登录数据库，点击天生，将DBCo妹妹文件夹复制到运用挨次目录，在cpp文件头削减如下:

#include ".DBCo妹妹DBTablesMyInfoOperator.h"

#include ".DBCo妹妹DBTablesRecordOperator.h"

#include ".DBCo妹妹DBTablesRecordViewOperator.h"

#include ".DBCo妹妹DBCo妹妹.h"

点击“工程”菜单，抉择“削减到工程”，将DBCo妹妹内所有cpp文件削减（搜罗DBTables下cpp文件）

调用示例

衔接数据库

void __fastcall TForm1::FormCreate(TObject *Sender)

{

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

  if(DBCo妹妹::Instance().ConnectDB(wstrConnStr))

  {

    DBGrid1->DataSource=DBCo妹妹::Instance().Tables<RecordViewOperator>(DBCo妹妹::RecordView)->Source();

  }

}

新增一条记实

void __fastcall TForm1::SpeedButton1Click(TObject *Sender)

{

     DBCo妹妹::Instance().Tables<MyInfoOperator>(DBCo妹妹::MyInfo)->New(LabeledEdit2->Text,LabeledEdit3->Text.ToDouble(),"admin",Now());

   }

}

删除了一条记实

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);

    DBCo妹妹::Instance().Tables<RecordOperator>(DBCo妹妹::Record)->Delete(strCondition);

  }

}

更新一条记实

 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);

    DBCo妹妹::Instance().Tables<MyInfoOperator>(DBCo妹妹::MyInfo)->Update(strName,fMoney,"admin",Now(),strCondition);

  }

}

取患上数据源

DBGrid1->DataSource=DBCo妹妹::Instance().Tables<RecordViewOperator>(DBCo妹妹::RecordView)->Source();
