Method Details

isUsingJtds

public boolean isUsingJtds()

setUsingJtds

public void setUsingJtds(boolean usingJtds)

createTable

protected void createTable(Table table,
 StringBuilder ddl,
 boolean temporary,
 boolean recreate)

Description copied from class: AbstractDdlBuilder

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 AbstractDdlBuilder

recreate - TODO

writeColumn

protected void writeColumn(Table table,
 Column column,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Outputs the DDL for the specified column.

Overrides:

writeColumn in class AbstractDdlBuilder

writeGeneratedColumn

protected void writeGeneratedColumn(Table table,
 Column column,
 StringBuilder ddl)

Overrides:

writeGeneratedColumn in class AbstractDdlBuilder

getNativeDefaultValue

protected String getNativeDefaultValue(Column column)

Description copied from class: AbstractDdlBuilder

Returns the native default value for the column.

Overrides:

getNativeDefaultValue in class AbstractDdlBuilder

Parameters:

column - The column

Returns:

The native default value

dropTable

protected void dropTable(Table table,
 StringBuilder ddl,
 boolean temporary,
 boolean recreate)

Description copied from class: AbstractDdlBuilder

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

Overrides:

dropTable in class AbstractDdlBuilder

recreate - TODO

writeExternalForeignKeyDropStmt

protected void writeExternalForeignKeyDropStmt(Table table,
 ForeignKey foreignKey,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Generates the statement to drop a foreignkey constraint from the database using an alter table statement.

Overrides:

writeExternalForeignKeyDropStmt in class AbstractDdlBuilder

Parameters:

table - The table

foreignKey - The foreign key

writeExternalIndexDropStmt

public void writeExternalIndexDropStmt(Table table,
 IIndex index,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

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

Overrides:

writeExternalIndexDropStmt in class AbstractDdlBuilder

dropExternalForeignKeys

public void dropExternalForeignKeys(Table table,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Creates external foreign key drop statements.

Overrides:

dropExternalForeignKeys in class AbstractDdlBuilder

Parameters:

table - The table

getSelectLastIdentityValues

public String getSelectLastIdentityValues(Table table)

Description copied from class: AbstractDdlBuilder

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 AbstractDdlBuilder

Parameters:

table - The table

Returns:

The sql, or null if the database does not support this

getEnableIdentityOverrideSql

protected String getEnableIdentityOverrideSql(Table table)

getDisableIdentityOverrideSql

protected String getDisableIdentityOverrideSql(Table table)

getQuotationOnStatement

protected String getQuotationOnStatement()

writeCopyDataStatement

public void writeCopyDataStatement(Table sourceTable,
 Table targetTable,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Writes a statement that copies the data from the source to the target table. Note that this copies only those columns that are in both tables. Database-specific implementations might redefine this method though they usually it suffices to redefine the #writeCastExpression(Column, Column) method.

Overrides:

writeCopyDataStatement in class AbstractDdlBuilder

Parameters:

sourceTable - The source table

targetTable - The target table

writeCastExpression

protected void writeCastExpression(Column sourceColumn,
 Column targetColumn,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Writes a cast expression that converts the value of the source column to the data type of the target column. Per default, simply the name of the source column is written thereby assuming that any casts happen implicitly.

Overrides:

writeCastExpression in class AbstractDdlBuilder

processChanges

protected void processChanges(Database currentModel,
 Database desiredModel,
 List<IModelChange> changes,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Processes the changes. The default argument performs several passes:

1. RemoveForeignKeyChange and RemoveIndexChange come first to allow for e.g. subsequent primary key changes or column removal.
2. RemoveTableChange comes after the removal of foreign keys and indices.
3. These are all handled together:
   RemovePrimaryKeyChange
AddPrimaryKeyChange
PrimaryKeyChange
RemoveColumnChange
AddColumnChange
ColumnAutoIncrementChange
ColumnDefaultValueChange
ColumnRequiredChange
ColumnDataTypeChange
ColumnSizeChange
   The reason for this is that the default algorithm rebuilds the table for these changes and thus their order is irrelevant.
4. AddTableChange
   needs to come after the table removal (so that tables of the same name are removed) and before the addition of foreign keys etc.
5. AddForeignKeyChange and AddIndexChange come last after table/column/primary key additions or changes.
6. RemoveTriggerChange come after the tables are completely built.
7. AddTriggerChange is done last.

Overrides:

processChanges in class AbstractDdlBuilder

processTableStructureChanges

protected void processTableStructureChanges(Database currentModel,
 Database desiredModel,
 Table sourceTable,
 Table targetTable,
 List<TableChange> changes,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

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 AbstractDdlBuilder

Parameters:

currentModel - The current database schema

desiredModel - The desired database schema

sourceTable - The original table

targetTable - The desired table

changes - The change objects for the target table

createUniqueIdentifier

protected String createUniqueIdentifier()

Creates a reasonably unique identifier only consisting of hexadecimal characters and underscores. It looks like d578271282b42fce__2955b56e_107df3fbc96__8000 and is 48 characters long.

Returns:
