                        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

                           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:

Throws:

IOException

writeExternalIndexDropStmt

public void writeExternalIndexDropStmt(Table table,

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

Overrides:

processTableStructureChanges in class SqlBuilder

Parameters:

IOException
