Classes:
• DataObjectException: DataObjectException class, used by Business Objects, catch all the DataObject Exceptions, will be passed to POs and handled there. Need to state the reasons. Usage: import myapp.business.*; try { some access of DOs } catch (SQLException sqlEx) { if (sqlEx.getSQLState().startsWith("02") && (sqlEx.getErrorCode() == 100)) { String msg = "Update or delete DO is out of synch"; throw new DataObjectException(msg, sqlEx); } else if (sqlEx.getSQLState().equals("S1000") && (sqlEx.getErrorCode() == -268)) { String msg = "Integrity constraint violation"; throw new DataObjectException(msg, sqlEx); } else { ...
• QueryBuilder: A QueryBuilder is a helper-object used by the xxxQuery classes. Stand-alone usage: QueryBuilder qb; qb = new QueryBuilder( "cats" ); or qb = new QueryBuilder( "cats", "name, age" ); ... qb.addWhereClause( "owner.name", "Smith", QueryBuilder.NOT_NULL, QueryBuilder.EXACT_MATCH ); qb.addWhereClause( "paws", 3, QueryBuilder.GREATER_THAN ); qb.addTwoColumnWhereClause( "cat.ownerId", "owner.Id", QueryBuilder.EQUAL ); ResultSet rs = qb.executeQuery( conn ); ... qb.reset();
• RDBColumnValue: After a Vector of RDBColumn objects is used to construct an instance of QueryBuilder, the QueryBuilder.getNextRow() method is used to return an RDBRow object which contains RDBColumnValue objects representing the column values in the returned row. An instance of RDBColumnValue is returned by the RDBRow.get() method. The value contained in the RDBColumnValue object is extracted using RDBColumnValue.get methods.
• ColumnNullException: ColumnNullException is thrown by RDBColumnValue.get methods when an unexpected NULL value in a column retrieved from the database. Application developers should treat ColumnNullException like other ChainedException objects. ColumnNullExceptions can be used to perform assertions upon queried data. Otherwise, they usually indicate programming errors caused by a misunderstanding of the database schema.
• ColumnTypeException: ColumnTypeException is thrown by RDBColumnValue.get methods when a column value is of an unexpected type. Application developers should treat ColumnTypeException like other ChainedException objects. ColumnTypeExceptions usually indicate programming errors caused by a misunderstanding of the database schema.
• InvalidRowColumnException: InvalidRowColumnException is thrown by the RDBRow.get methods when a requested column does not exist in the current row. Application developers should treat InvalidRowColumnException like other ChainedException objects. InvalidRowColumnExceptions indicate programming errors.
• QueryException: QueryException is thrown by QueryBuilder.getNextRow and getRows methods when the database query could not be performed. Application developers should treat QueryException like other ChainedException objects. QueryExceptions indicate run-time errors in accessing the database.
• RDBRow: An instance of RDBRow is returned by the QueryBuilder.getNextRow() method. An RDBRow contains RDBColumnValue objects corresponding to the RDBColumn objects used to construct the instance of QueryBuilder. in a particular table in the database.
• RDBTable: An instance of RDBTable describes a particular table in the database. It is used to construct RDBColumn objects which can then be used to perform database queries using the QueryBuilder class.
• RDBColumn: An instance of RDBColumn describes a particular column in a particular table in the database. It is used to construct database queries using the QueryBuilder class.
