Constructor Details

Oracle8Builder

public Oracle8Builder(Platform platform)

Creates a new builder instance.

platform - The plaftform this builder belongs to

Method Details

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

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

createAutoIncrementTrigger

protected void createAutoIncrementTrigger(Table table,
 Column column)
                                   throws IOException

Creates the trigger 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

dropAutoIncrementTrigger

protected void dropAutoIncrementTrigger(Table table,
 Column column)
                                 throws IOException

Drops the trigger used for the auto-increment of the given column.

Parameters:

table - The table

column - The column

Throws:

IOException

createTemporaryTable

protected void createTemporaryTable(Database database,
 Table table,
 Map parameters)
                             throws IOException

Outputs the DDL to create the given temporary table. Per default this is simply a call to SqlBuilder.createTable(Database, Table, Map).

Overrides:

createTemporaryTable in class SqlBuilder

Parameters:

database - The database model

table - The table

parameters - Additional platform-specific parameters for the table creation

Throws:

IOException

dropTemporaryTable

protected void dropTemporaryTable(Database database,
 Table table)
                           throws IOException

Outputs the DDL to drop the given temporary table. Per default this is simply a call to SqlBuilder.dropTable(Table).

Overrides:

dropTemporaryTable in class SqlBuilder

Parameters:

database - The database model

table - The table

Throws:

IOException

dropExternalForeignKeys

public void dropExternalForeignKeys(Table table)
                             throws IOException

Creates external foreignkey drop statements.

Overrides:

dropExternalForeignKeys in class SqlBuilder

Parameters:

table - The table

Throws:

IOException

writeExternalIndexDropStmt

public void writeExternalIndexDropStmt(Table table,
 Index index)
                                throws IOException

Generates the statement to drop a non-embedded index from the database.

Overrides:

writeExternalIndexDropStmt in class SqlBuilder

Parameters:

table - The table the index is on

index - The index to drop

Throws:

IOException

printDefaultValue

protected void printDefaultValue(Object defaultValue,
 int typeCode)
                          throws IOException

Prints the default value of the column.

Overrides:

printDefaultValue in class SqlBuilder

Parameters:

defaultValue - The default value

typeCode - The type code to write the default value for

Throws:

IOException

getNativeDefaultValue

protected String getNativeDefaultValue(Column column)

writeColumnAutoIncrementStmt in class SqlBuilder

Parameters:

table - The table

column - The column

Throws:

IOException

getSelectLastIdentityValues

public String getSelectLastIdentityValues(Table table)

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,

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
