BTI_API PvOpenDatabase(

BTI_LONG hConnection,

BTI_CHAR_PTR dbName,

BTI_CHAR_PTR dbUser,

BTI_CHAR_PTR dbPassword,

BTI_WORD_PTR dbHandle);


In	hConnection	Connection handle that identifies the server. Connection handles are obtained with the PvConnectServer() function.
In	dbName	Name of the database.
In	dbUser	Database user name if security is defined.
In	dbPassword	Database password if security is defined.
Out	dbHandle	Returned handle to the database.


P_OK	The operation was successful.
P_E_INVALID_HANDLE	Invalid connection handle.
P_E_NULL_PTR	Call with NULL pointer.
P_E_ACCESS_RIGHT	Insufficient access right for the operation.
P_E_FAIL	Failed to open the database for other reasons.
PCM_errSessionSecurityError	Invalid user name or password.

The following preconditions must be met:

•

DTI session started by calling PvStart()

•

Connection established by PvConnectServer() or if you are performing the operation on a local machine, P_LOCAL_DB_CONNECTION may be used as the connection handle.

•

If the database has security enabled, you must specify a valid database user name and password. Security for the returned database handle is enforced based on the access rights defined for the database, and should match behavior seen in SQL or ODBC access methods.
