MFC SQL(ODBC)数据库操作

1.添加ODBC 类

2.定义数据库链接

#define DATABASE_OPEN_SQL "DRIVER={Progress OpenEdge 10.2B Driver};DSN=asd;DB=zxc;UID=vfr;PWD=kjh;HOST=192.0.21.45;PORT=54198;"

3.操作数据库

CRecordset rs;
odbc m_odbc;

void GetSQLData()//查询
{
    m_odbc.Open(NULL,false,false,_T(DATABASE_OPEN_SQL),true);
    if(m_odbc.IsOpen())
	{
        rs.m_pDatabase = &m_odbc;
		CString s;
		rs.Open(CRecordset::forwardOnly, _T("select * from pub.els_name"));//表名els_name
		if(rs.IsOpen())
		{
			
			CString strVal;
			while(!rs.IsEOF())
			{
			
				rs.GetFieldValue((short)0,strVal);//获取第一行第一列数据
			    rs.GetFieldValue((short)1,strVal);//获取第一行第二列数据
				//依此类推
				//...
