public int getPriority()

isCorrectDatabaseImplementation

public boolean isCorrectDatabaseImplementation(DatabaseConnection conn)
                                        throws DatabaseException

Description copied from interface: Database

Is this AbstractDatabase subclass the correct one to use for the given connection.

Throws:

DatabaseException

supportsTablespaces

public boolean supportsTablespaces()

getViewDefinition

public String getViewDefinition(String schemaName,
                                String name)
                         throws DatabaseException

Specified by:

getViewDefinition in interface Database

Overrides:

getViewDefinition in class AbstractDatabase

Throws:

DatabaseException

parseDate

public Date parseDate(String dateAsString)
               throws DateParseException

Specified by:

parseDate in interface Database

Overrides:

parseDate in class AbstractDatabase

Throws:

DateParseException

public boolean isLocalDatabase()
                        throws DatabaseException

Description copied from class: AbstractDatabase

Default implementation, just look for "local" IPs

Specified by:

isLocalDatabase in interface Database

Overrides:

isLocalDatabase in class AbstractDatabase

Throws:

DatabaseException

supportsSequences

public boolean supportsSequences()

Description copied from class: AbstractDatabase

Does the database type support sequence.

Specified by:

supportsSequences in interface Database

Overrides:

supportsSequences in class AbstractDatabase

getDefaultDatabaseSchemaName

protected String getDefaultDatabaseSchemaName()
                                       throws DatabaseException

Overrides:

getDefaultDatabaseSchemaName in class AbstractDatabase

getDateLiteral

public String getDateLiteral(String isoDate)

Description copied from class: AbstractDatabase

Return a date literal with the same value as a string formatted using ISO 8601.
