Constructor Detail

MckoiBuilder

public MckoiBuilder(Platform platform)
Creates a new builder instance.

Parameters:
platform - The plaftform this builder belongs to
Method Detail

createTable

public void createTable(Database database,
                        Table table,
                        Map parameters)
                 throws IOException
Outputs the DDL to create the table along with any non-external constraints as well as with external primary keys and indices (but not foreign keys).

Overrides:
createTable in class SqlBuilder
Parameters:
database - The database model
table - The table
parameters - Additional platform-specific parameters for the table creation
Throws:
IOException

dropTable

public void dropTable(Table table)
               throws IOException
Outputs the DDL to drop the table. Note that this method does not drop foreign keys to this table. Use SqlBuilder.dropTable(Database, Table) if you want that.

Overrides:
dropTable in class SqlBuilder
Parameters:
table - The table to drop
Throws:
IOException

createAutoIncrementSequence

protected void createAutoIncrementSequence(Table table,
                                           Column column)
                                    throws IOException
Creates the sequence necessary for the auto-increment of the given column.

Parameters:
table - The table
column - The column
Throws:
IOException

dropAutoIncrementSequence

protected void dropAutoIncrementSequence(Table table,
                                         Column column)
                                  throws IOException
Drops the sequence used for the auto-increment of the given column.

Parameters:
table - The table
column - The column
Throws:
IOException

writeColumnDefaultValue

protected void writeColumnDefaultValue(Table table,
                                       Column column)
                                throws IOException
Prints the default value of the column.

Overrides:
writeColumnDefaultValue in class SqlBuilder
Parameters:
table - The table
column - The column
Throws:
IOException

getSelectLastIdentityValues

public String getSelectLastIdentityValues(Table table)
Generates the SQL for querying the id that was created in the last insertion operation. This is obviously only useful for pk fields that are auto-incrementing. A database that does not support this, will return null.

Overrides:
getSelectLastIdentityValues in class SqlBuilder
Parameters:
table - The table
Returns:
The sql, or null if the database does not support this

processTableStructureChanges

protected void processTableStructureChanges(Database currentModel,
                                            Database desiredModel,
                                            Table sourceTable,
                                            Table targetTable,
                                            Map parameters,
                                            List changes)
                                     throws IOException
Allows database-specific implementations to handle changes in a database specific manner. Any handled change should be applied to the given current model (which is a copy of the real original model) and be removed from the list of changes.
In the default implementation, all AddPrimaryKeyChange changes are applied via an ALTER TABLE ADD CONSTRAINT statement.

Overrides:
processTableStructureChanges in class SqlBuilder
Parameters:
currentModel - The current database schema
desiredModel - The desired database schema
sourceTable - The original table
targetTable - The desired table
parameters - The creation parameters for the table
changes - The change objects for the target table
Throws:
IOException
