using namespace std;

    }

    string GetName() const

        return m_Name;

Dao定义

#include "BaseOCIDao.h"

class TDao:BaseOCIDao

{

public:

    TDao(){}

    TDao(string ip,unsigned int port,string inst,string user,string pwd,POCI_ERROR ErrHandler,unsigned int mode):

    BaseOCIDao(ip,port,inst,user,pwd,ErrHandler,mode)

    {

    }

    ~TDao(){}

    BOOL Insert(TModel* model)

    {

        char* sql = "insert into TabName(id,name) values (:id,:name)";

        OCI_Statement* stmt = PrepareBindStmt(sql);

        OCI_BindInt(stmt,":id",&model->m_ID);

        OCI_BindString(stmt,":name",model->m_Name,NameSize);

        return ExecuteBindStmt(stmt);

    }

    BOOL Update(TModel* model)

    {

        char* sql = "update TabName set name=:name where id=:id";

        OCI_Statement* stmt = PrepareBindStmt(sql);

        OCI_BindInt(stmt,":id",&model->m_ID);

        OCI_BindString(stmt,":name",model->m_Name,NameSize);

        return ExecuteBindStmt(stmt);

    }

    BOOL Delete(string cond)

    {

        string sql = "delete from TabName";

        if(cond!="")

            sql+=" where " + cond;

        return ExecuteSql(sql.c_str());

    }

    vector<TModel*> Select(string cond)

    {

        vector<TModel*> resVec;

        string sql = "select id,name from TabName";

        if(cond!="")

            sql+=" where " + cond;

        OCI_Resultset* rs = QuerySql(sql.c_str());

        while(OCI_FetchNext(rs))

        {

            TModel *model = new TModel();

            model->SetID(OCI_GetInt(rs,));

            model->SetName(OCI_GetString(rs,));

            resVec.push_back(model);

        }

    BOOL Exist(TModel* model)

        char* sql = "select id from TabName where name=:name";

        OCI_Statement* stmt = PrepareBindStmt(sql);

        OCI_BindString(stmt,":name",model->m_Name,NameSize);

        OCI_Resultset* rs = QueryBindStmt(stmt);

        if(OCI_FetchNext(rs))

        {

            model->SetID(OCI_GetInt(rs,));

            return TRUE;

        }

        else

            return FALSE;

    }

};

DaoFactory定义

void err_handler(OCI_Error *err)

{

    int err_type = OCI_ErrorGetType(err);

    print_text("\n");

    if (err_type == OCI_ERR_WARNING)

    {

        print_text("> WARNING : ");

    }

    else

    {

        print_text("> ERROR   : ");

    }

    print_ostr(OCI_ErrorGetString(err));

    print_text("\n");

}

class DaoFactory{

private:

    string m_ip;

    unsigned int m_port;

    string m_inst;

    string m_user;

    string m_pwd;

    unsigned int m_mode;

private:

    DaoFactory(){

        m_ip = "127.0.0.1";

        m_port = ;

        m_inst = "orcl";

        m_user = "user";

        m_pwd = "password";

        m_mode = OCI_ENV_DEFAULT;

    }

public:

    static DaoFactory* GetInstance()

    {

        static DaoFactory factory;

        return &factory;

    }

    ~DaoFactory(){}

public:

    TDao* CreateTDao()

    {

        TDao* dao = new TDao(m_ip,m_port,m_inst,m_user,m_pwd,err_handler,m_mode);

        return dao;

    }

};

简单情况

使用DaoFactory创建dao对象 dao
打开数据库连接 dao->Connect
执行搜索或增删改操作 dao->Select dao->Insert ….
关闭数据库连接 dao->DisConnect
删除dao对象 delete dao;

更复杂的情况

共享数据库连接进行查询

使用DaoFactory创建两个dao对象：DaoParent, DaoChild；
DaoParent->AddChildDao(DaoChild);
打开数据库连接DaoParent->Connect();
搜索 DaoParent->Select();DaoChild->Select();
关闭数据库连接 DaoParent->DisConnect();
删除dao对象内存;delete DaoChild; delete DaoParent;

共享数据库事务，进行增删改操作

使用DaoFactory创建两个dao对象：DaoParent, DaoChild；
DaoParent->AddChildDao(DaoChild);
打开数据库连接DaoParent->Connect();
打开事务 DaoParent-> BeginTrans
执行增删改操作 DaoParent->Insert();DaoChild->Update();。。。
提交或回滚事务 DaoParent-> Commit DaoParent-> Rollback
关闭事务 DaoParent-> EndTrans
关闭数据库连接 DaoParent->DisConnect();
删除dao对象内存;delete DaoChild; delete DaoParent;

4. 自动生成Model和Dao的工具设计

工具从输入流中读入一组规定格式的数据，按照此数据构建Model和Dao类代码。

输入内容格式规定

类名

数据库表名

字段个数N

字段1 类型1 数据库字段名1

…

字段N 类型N 数据库字段名N

支持的类型

类型	真实类型	数据库对应类型
int	int	number(10)
unsigned int	unsigned int	number(10)
short	short	number(5)
unsigned short	unsigned short	number(5)
float	float	binary_float
double	double	binary_double
string	char[]	varchar2()
big_int	long long	number(14)
big_uint	unsigned long long	number(14)

例子：

User类有3个字段，ID，Name，Pwd

可输入如下：

User

UserTable

ID unsigned int ID

Name string Name

Pwd string Pwd

自动生成工具根据BaseMode和BaseOCIDao生成，可根据需要将生成后的Model和Dao进行修改。对于stirng类型的数据，自动生成Model后，可修改xxxSize宏，设置string类型字段的长度。
