Detailed Description

Obsolete class - implementation of Connection interface using Oracle v. 7 OCI. Use Oracle8iConnection instead.

Warning:

This class uses cursors of type OracleCursor. This cursor doesn't correctly implement methods Cursor::_PreExecBind(const char *,const int,const void *,const int,const IopcDataType,bool) and Cursor::_PreFetchBind(const int,const void *,const int,const IopcDataType,bool *).

This class was nearly undocumented in POLiTe - a few of old comments can be found in source code - not in doxygen. I (Josef Troch) have added some comments, but persistence layer IOPC does not use this class!

Member Function Documentation

bool OracleConnection::_Sql (  const char *  sqlCommand  )  [protected, virtual]

Processes SQL command (sqlCommand) - calls _Open(), _Prepare(), _Execute() and _Close() for it. Parameters: sqlCommand  SQL statement to be processed. Reimplemented from Connection.

bool OracleConnection::_Commit (   )  [protected, virtual]

Commits actual transaction. Implements Connection.

bool OracleConnection::_Rollback (   )  [protected, virtual]

Performs rollback of actual transaction. Implements Connection.

bool OracleConnection::_Savepoint (  const char *  name  )  [protected, virtual]

Creates savepoint with given name (name). If your database doesn't support savepoints, feel free to make fake implementation of this function. Implements Connection.

bool OracleConnection::_RollbackToSavepoint (  const char *  name  )  [protected, virtual]

Performs rollback to savepoint with given name (name). If your database doesn't support savepoints, feel free to make fake implementation of this function. Implements Connection.

bool OracleConnection::_NextOID (  long int &  nxtoid, long int &  nxtsn )  [protected, virtual]

Generates new OID and Serial Number for a new object. Obsolete function used by POLiTe-style persistent classes. IopcPersistentObject ancestors don't use this function, so you can make fake implementation of this function if you don't need to support POLiTe-style persistent classes. Parameters: nxtoid  Resulting OID. nxtsn  Resulting Serial Number Implements Connection.

bool OracleConnection::_NextSN (  long int  curoid, long int &  nxtsn )  [protected, virtual]

Generates new Serial Number for object with given OID. Obsolete function used by POLiTe-style persistent classes. IopcPersistentObject ancestors don't use this function, so you can make fake implementation of this function if you don't need to support POLiTe-style persistent classes. Parameters: curoid  The OID. nxtsn  Resulting Serial Number Implements Connection.

bool OracleConnection::Sql (  const char *  sqlCommand  )  [virtual]

Updates all objects in cache, then calls _Sql(). Parameters: sqlCommand  SQL statement to be processed Reimplemented from Connection.

bool OracleConnection::Commit (   )  [virtual]

Saves modified objects to the database, then commits actual transaction. Reimplemented from Connection.

bool OracleConnection::Rollback (   )  [virtual]

Performs rollback of actual transaction, then removes all persistent objects from the memory. Reimplemented from Connection.

bool OracleConnection::Savepoint (  const char *  name  )  [virtual]

Saves modified objects to the database, then creates savepoint. Parameters: name  Name of savepoint to be created. Reimplemented from Connection.

bool OracleConnection::RollbackToSavepoint (  const char *  name  )  [virtual]

Performs rollback to savepoint, then destroys all data in memory. Parameters: name  Name of savepoint to rollback to. Reimplemented from Connection.

bool OracleConnection::Disconnect (   )  [virtual]

Commits actual transaction, then disconnects from database. Reimplemented from Connection.

bool OracleConnection::Abort (   )  [virtual]

Performs rollback of actual transaction, then disconnect from database. Reimplemented from Connection.

bool OracleConnection::Autocommit (  bool  ac  )  [virtual]

Turns on / off autocommit (automatic commit of every SQL data manipulation statement). Parameters: ac  1 to turn autocommit on, 0 to turn it off. Implements Connection.

Cursor * OracleConnection::_GetNewCursor (   )  [protected, virtual]

Creates and returns new cursor. Implements Connection.
