org.apache.ddlutils.alteration.TableChangeImplBase

org.apache.ddlutils.alteration.RecreateTableChange

All Implemented Interfaces:

ModelChange, TableChange

public class RecreateTableChange
extends TableChangeImplBase

Represents the recreation of a table, i.e. creating a temporary table using the target table definition, copying the data from the original table into this temporary table, dropping the original table and finally renaming the temporary table to the final table. This change is only created by the model comparator if the table definition change predicate flags a table change as unsupported.

Constructor Detail

RecreateTableChange

public RecreateTableChange(String tableName,
                   Table targetTable,
                   List originalChanges)

Creates a new change object for recreating a table. This change is used to specify that a table needs to be dropped and then re-created (with changes). In the standard model comparison algorithm, it will replace all direct changes to the table's columns (i.e. foreign key and index changes are unaffected).

Parameters:

tableName - The name of the table

targetTable - The table as it should be; note that the change object will keep a reference to this table which means that it should not be changed after creating this change object

originalChanges - The original changes that this change object replaces

Method Detail

getOriginalChanges

public List getOriginalChanges()

Returns the original table changes, one of which is unsupported by the current platform.

Returns:

The table changes

getTargetTable

public Table getTargetTable()

Returns the target table definition. Due to when an object of this kind is created in the comparison process, this table object will not have any foreign keys pointing to or from it, i.e. it is independent of any model.

Returns:

The table definition

apply

public void apply(Database database,
         boolean caseSensitive)

Applies this change to the given database.

Parameters:

database - The database

caseSensitive - Whether the case of names matters
