SQL server Cursor

Hi,

I use the following code to connect to SQL Server. but when I use edit() function of CRecordset to update a record in databse, it reports error.

//connect to DB
m_Database.OpenEx( ConnectionString, CDatabase::noOdbcDialog )

//update records
m_pRecordset->Edit(); <-- report a "DBCore.cpp line 66 assertion"
m_pRecordset->Update();
 
later, I change the connection as:
m_Database.OpenEx( ConnectionString, CDatabase::noOdbcDialog | CDatabase::useCursorLib))

then it works fine.

My question is:
1> Does the edit() function use a cursor?
2>SQL server Driver itself supports cursor ability, why I have to use other cursor library?
3> how do I use the SQL server driver's cursor ability?

Could you give some code example? I am using vc++

Thanks,

Gossip

Just a sugestion (maybe a stupidity): try this

//connect to DB
m_Database.OpenEx( ConnectionString, CDatabase::noOdbcDialog )

m_pRecordset->Open();

//update records
m_pRecordset->Edit(); <-- report a "DBCore.cpp line 66 assertion"
m_pRecordset->Update();
