Constructor Detail

SapDbBuilder

public SapDbBuilder(Platform platform)

Creates a new builder instance.

Parameters:

platform - The plaftform this builder belongs to

Method Detail

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

writeColumnAutoIncrementStmt

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

Prints that the column is an auto increment column.

Overrides:

writeColumnAutoIncrementStmt in class SqlBuilder

Parameters:

table - The table

column - The column

Throws:

IOException

writeExternalPrimaryKeysCreateStmt

protected void writeExternalPrimaryKeysCreateStmt(Table table,
                                                  Column[] primaryKeyColumns)
                                           throws IOException

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

Overrides:

writeExternalPrimaryKeysCreateStmt in class SqlBuilder

Parameters:

table - The table

primaryKeyColumns - The primary key columns

Throws:

IOException

writeExternalForeignKeyCreateStmt

protected void writeExternalForeignKeyCreateStmt(Database database,
                                                 Table table,
                                                 ForeignKey key)
                                          throws IOException

Writes a single foreign key constraint using a alter table statement.

Overrides:

writeExternalForeignKeyCreateStmt in class SqlBuilder

Parameters:

database - The database model

table - The table

key - The foreign key

Throws:

IOException

writeExternalForeignKeyDropStmt

protected void writeExternalForeignKeyDropStmt(Table table,
                                               ForeignKey foreignKey)
                                        throws IOException

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

Overrides:

writeExternalForeignKeyDropStmt in class SqlBuilder

Parameters:

table - The table

foreignKey - The foreign key

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
