ado链接数据库

[qq_40826881]

pConn->ConnectionString = "Provider=OraOLEDB.Oracle.1;DataSource=\" (DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.26.51)(PORT = 1521)) )(CONNECT_DATA = (SID =orcl))) \";User ID=scott;Password=scott";

pConn->ConnectionString = "Provider=OraOLEDB.Oracle.1;DataSource=;User ID=scott;Password=scott";

我DataSource中无论输入什么都是，链接的同一个数据库。
求大神解答
