org.apache.ddlutils.platform.sapdb.SapDbBuilder
The SQL Builder for SapDB.

_log, SIZE_PLACEHOLDER |
Constructor Summary | |
SapDbBuilder(Platform platform)
Creates a new builder instance. |
Method Summary | |
void |
dropTable(Table table)
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. |
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 . |
protected void |
processChange(Database currentModel,
Database desiredModel,
AddColumnChange change)
Processes the addition of a column to a table. |
protected void |
processChange(Database currentModel,
Database desiredModel,
ColumnDefaultValueChange change)
Processes the change of the default value of a column. |
protected void |
processChange(Database currentModel,
Database desiredModel,
ColumnRequiredChange change)
Processes the change of the required constraint of a column. |
protected void |
processChange(Database currentModel,
Database desiredModel,
RemoveColumnChange change)
Processes the removal of a column from a table. |
protected void |
processChange(Database currentModel,
Database desiredModel,
RemovePrimaryKeyChange change)
Processes the removal of a primary key from a table. |
protected void |
processTableStructureChanges(Database currentModel,
Database desiredModel,
Table sourceTable,
Table targetTable,
Map parameters,
List changes)
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. |
protected void |
writeColumnAutoIncrementStmt(Table table,
Column column)
Prints that the column is an auto increment column. |
