moveCorr

public static void moveCorr(DataObject doFrom,
                            DataObject doTo,
                            java.lang.String columnNameToExclude)

Copies matching attributes from one table row to another.

Parameters:

doFrom - the source data object

doTo - the target data object

columnNameToExclude - the name of the column not be copied

                            DataObject doTo)

moveCorr

public static void moveCorr(java.lang.String values,
                            DataObject dataObject)

Move corresponding values from a value concatenation to a data object.

Parameters:

values - the concatenated value string using separator

dataObject - the data object to be filled with values

DoChangeLog.VALUE_SEPARATOR

transferValue

public static void transferValue(java.lang.String columnName,
                                 java.lang.String fromTable,
                                 java.lang.String toTable,
                                 IdentifyTemplate idTempl,
                                 Identifier id,
                                 java.sql.Connection connection)

Transfers a column value from one table to another. Useful for BLOB values, which are not transfered via moveCorr.

Parameters:

columnName - the name of the column to be transfered

fromTable - the table from which the column value is to read

toTable - the table to which the column value is to write

idTempl - the identify template to use to specify the row

id - the identifier of the row which is to change

connection - the database connection to use
