Drops the sequence used for the auto-increment of the given column.

Parameters:

Throws:

IOException

dropAutoIncrementTrigger

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

Drops the trigger used for the auto-increment of the given column.

Parameters:

IOException

createTemporaryTable

protected void createTemporaryTable(Database database,
                        Table table,
                        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 - 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

dropForeignKeys

public void dropForeignKeys(Table table)
                     throws IOException

Creates external foreignkey drop statements.

Overrides:

Returns:

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

                            throws IOException

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 SqlBuilder

Parameters:

sourceColumn - The source column

targetColumn - The target column

Throws:

IOException

getSqlType

protected String getSqlType(Column column)

Returns the full SQL type specification (including size and precision/scale) for the given column.
