| Method Summary | |
| protected void | assignAutoincrementIdentityColumns(ClassDescriptor cld, Object target)
| | protected void | assignAutoincrementSequences(ClassDescriptor cld, Object target)
| | public void | executeDelete(ClassDescriptor cld, Object obj)
performs a DELETE operation against RDBMS. | | public void | executeDelete(Query query, ClassDescriptor cld)
Performs a DELETE operation based on the given
Query against RDBMS. | | public void | executeInsert(ClassDescriptor cld, Object obj)
performs an INSERT operation against RDBMS. | | public ResultSetAndStatement | executeQuery(Query query, ClassDescriptor cld)
performs a SELECT operation against RDBMS. | | public ResultSetAndStatement | executeSQL(String sqlStatement, ClassDescriptor cld, boolean scrollable)
| | public ResultSetAndStatement | executeSQL(String sql, ClassDescriptor cld, ValueContainer[] values, boolean scrollable)
performs a SQL SELECT statement against RDBMS. | | public void | executeUpdate(ClassDescriptor cld, Object obj)
performs an UPDATE operation against RDBMS. | | public int | executeUpdateSQL(String sqlStatement, ClassDescriptor cld)
| | public int | executeUpdateSQL(String sqlStatement, ClassDescriptor cld, ValueContainer[] values1, ValueContainer[] values2)
performs a SQL UPDTE, INSERT or DELETE statement against RDBMS.
Parameters:
sqlStatement - the query string.
Parameters:
cld - ClassDescriptor providing meta-information. | | protected boolean | isStoredProcedure(String sql)
Check if the specified sql-string is a stored procedure
or not. | | public Object | materializeObject(ClassDescriptor cld, Identity oid)
performs a primary key lookup operation against RDBMS and materializes
an object from the resulting row. |
| JdbcAccessImpl | | public JdbcAccessImpl(PersistenceBroker broker)(Code) | | constructor is private, use getInstance to get
the singleton instance of this class
|
| executeInsert | | public void executeInsert(ClassDescriptor cld, Object obj) throws PersistenceBrokerException(Code) | | performs an INSERT operation against RDBMS.
Parameters:
obj - The Object to be inserted as a row of the underlying table.
Parameters:
cld - ClassDescriptor providing mapping information. |
| executeUpdate | | public void executeUpdate(ClassDescriptor cld, Object obj) throws PersistenceBrokerException(Code) | | performs an UPDATE operation against RDBMS.
Parameters:
obj - The Object to be updated in the underlying table.
Parameters:
cld - ClassDescriptor providing mapping information. |
| isStoredProcedure | | protected boolean isStoredProcedure(String sql)(Code) | | Check if the specified sql-string is a stored procedure
or not.
Parameters:
sql - The sql query to check True if the query is a stored procedure, else false is returned. |
| materializeObject | | public Object materializeObject(ClassDescriptor cld, Identity oid) throws PersistenceBrokerException(Code) | | performs a primary key lookup operation against RDBMS and materializes
an object from the resulting row. Only skalar attributes are filled from
the row, references are not resolved.
Parameters:
oid - contains the primary key info.
Parameters:
cld - ClassDescriptor providing mapping information. the materialized object, null if no matching row was found or ifany error occured. |
