determine which mode to use as default mode here: UPDATE highly specific to operation INSERT / UPDATE / DELETE / SELECT

Specified by:
selectMode in class DatabaseAction

honourAutoIncrement

protected boolean honourAutoIncrement()
determine whether autoincrement columns should be honoured by this operation. This is usually snsible only for INSERTs.

Specified by:
honourAutoIncrement in class DatabaseAction

getColumnValues

protected Object[][] getColumnValues(Configuration tableConf,
                                     DatabaseAction.CacheHelper queryData,
                                     Map objectModel)
                              throws ConfigurationException,
                                     ServiceException
Fetch all values for all columns that are needed to do the database operation.

Throws:
ConfigurationException
ServiceException

protected DatabaseAction.CacheHelper getQuery(Configuration table,
                                              Map modeTypes,
                                              Map defaultModeNames)
                                       throws ConfigurationException,
                                              ServiceException

getQuery in class DatabaseAction
Parameters:
table - the table's configuration object
Returns:
the insert query as a string
Throws:
ConfigurationException
ServiceException
