migrateDataToRemoveColumn

protected boolean migrateDataToRemoveColumn

Constructor Details

Db2DdlBuilder

public Db2DdlBuilder()

Method Details

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

writeColumnAutoIncrementStmt

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

Description copied from class: AbstractDdlBuilder

Prints that the column is an auto increment column.

Overrides:

writeColumnAutoIncrementStmt in class AbstractDdlBuilder

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

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

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

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

writeAlterColumnDataTypeToBigInt

protected boolean writeAlterColumnDataTypeToBigInt(ColumnDataTypeChange change,
 StringBuilder ddl)

Overrides:

writeAlterColumnDataTypeToBigInt in class AbstractDdlBuilder

processChange

protected void processChange(Database currentModel,
 Database desiredModel,
 AddColumnChange change,
 StringBuilder ddl)

processChange

protected void processChange(Database currentModel,
 Database desiredModel,
 RemoveColumnChange change,
 StringBuilder ddl)

processChange

protected void processChange(Database currentModel,
 Database desiredModel,
 RemovePrimaryKeyChange change,
 StringBuilder ddl)

processChange

protected void processChange(Database currentModel,
 Database desiredModel,
 PrimaryKeyChange change,
 StringBuilder ddl)

writeExternalPrimaryKeysCreateStmt

protected void writeExternalPrimaryKeysCreateStmt(Table table,
 Column[] primaryKeyColumns,
 StringBuilder ddl)

Description copied from class: AbstractDdlBuilder

Writes the primary key constraints of the table as alter table statements.

Overrides:

writeExternalPrimaryKeysCreateStmt in class AbstractDdlBuilder

Parameters:

table - The table

primaryKeyColumns - The primary key columns

writeReorgStmt

protected void writeReorgStmt(Table table,
 StringBuilder ddl)

writeCascadeAttributesForForeignKeyUpdate

protected void writeCascadeAttributesForForeignKeyUpdate(ForeignKey key,
 StringBuilder ddl)

Overrides:

writeCascadeAttributesForForeignKeyUpdate in class AbstractDdlBuilder
