Question

 VS2008  ORACLE11G 
Environment *env = Environment::createEnvironment();
{
Connection *conn = env->createConnection( userName, password);到这里就报错Unhandled exception at 0x75219617 in Oracle_occi.exe: Microsoft C++ exception: oracle::occi::SQLException at memory location 0x0026fb64..到底是怎么回事啊....

Answer 1

createConnection( userName, password);
不要db的？汗#include  <occi.h> 
using  namespace  oracle::occi;
                                                                                                                                                                          Environment *env;
Connection *conn;
//连接
env = Environment::createEnvironment(Environment::OBJECT);
conn = env->createConnection(user,psw,db);
//关闭
stmt->closeResultSet(rset);
conn->terminateStatement(stmt);

Answer 2

  conn = env->createConnection( "ffadsf","11444444411","Eden");
Eden是创建的数据库  
还是不行 还是Unhandled exception at 0x75219617 in Oracle_occi.exe: Microsoft C++ exception: oracle::occi::SQLException at memory location 0x0026fb64.. 是string 类型的问题吗?

Answer 3

  conn = env->createConnection( "ffadsf","11444444411","Eden"); 
用户名密码对不对啊？
看下别人怎么连的：
