Detailed Description

Obsolete class - implementation of Database interface using Oracle v. 7 OCI. Use Oracle8iDatabase instead.

Warning:

This class creates connections of type OracleConnection and uses cursors of type OracleCursor. These cursors don'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 OracleDatabase::Commit (   )  [virtual]

Saves all modified objects to DB, then performs commit on all connections to the database. Reimplemented from Database.

bool OracleDatabase::Rollback (   )  [virtual]

Performs rollback on all connections to the database, then destroys all copies in memory. Reimplemented from Database.

class Connection * OracleDatabase::Connect (  const char *  UserName, const char *  Password )  [virtual]

Creates new connection to the database After successful connection this function should call afterConnectHandler if runAfterConnectHandler is set. Implementation should return ObjLibException_ConnectionError in case of error. Parameters: UserName  User name to connect as. Password  Password for user UserName. Returns: Created Connection object. Implements Database.

bool OracleDatabase::WriteDDL (  std::ofstream &  S  )  [virtual]

Generates DDL statements needed for old POLiTe style persistence to work Obsolete function. IopcPersistentObject ancestors don't need this generated DDL statements. So you can make fake implementation of this function if you don't need to support POLiTe-style persistent classes. Parameters: S  Stream to output DDL statements into. Implements Database.

char * OracleDatabase::ColumnTypeDDL (  char  colType, int  colLength )  [virtual]

Returns correct database column type for given attribute type. 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: colType  Type of the attribute (TYPE_INT etc.) colLength  Length of the attribute (for int-s etc. sizeof()) See also: DatabaseSqlStatements::getRecommendedColumnType() Implements Database.

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

Performs commit on all connections to the database immediately (modified objects are not saved into DB). Reimplemented from Database.

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

Performs rollback on all connections to the database (doesn't destroy copies in memory). Reimplemented from Database.
