DerbyDatabase

public DerbyDatabase()

Method Details

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

getDefaultDriver

public String getDefaultDriver(String url)

Description copied from interface: Database

If this database understands the given url, return the default driver class name. Otherwise return null.

getPriority

public int getPriority()

supports

public boolean supports(Class<? extends DatabaseObject> object)

Description copied from interface: Database

Whether this database supports the specified object type. It is invoking the deprecated methods to ensure that extensions are not broken, but once those are removed it will return only true

Parameters:

object - the object type to check

Returns:

true if the database supports the object type, false otherwise

supportsSchemas

public boolean supportsSchemas()

Description copied from interface: Database

Whether this database supports schemas

Specified by:

supportsSchemas in interface Database

Overrides:

supportsSchemas in class AbstractJdbcDatabase

jdbcCallsCatalogsSchemas

public boolean jdbcCallsCatalogsSchemas()

Overrides:

jdbcCallsCatalogsSchemas in class AbstractJdbcDatabase

getDefaultPort

public Integer getDefaultPort()

getDefaultDatabaseProductName

protected String getDefaultDatabaseProductName()

Specified by:

getDefaultDatabaseProductName in class AbstractJdbcDatabase

correctObjectName

public String correctObjectName(String objectName,
 Class<? extends DatabaseObject> objectType)

Description copied from interface: Database

Fix the object name to the format the database expects, handling changes in case, etc.

Specified by:

correctObjectName in interface Database

Overrides:

correctObjectName in class AbstractJdbcDatabase

getShortName

public String getShortName()

Description copied from interface: Database

Returns an all-lower-case short name of the product. Used for end-user selecting of database type such as the DBMS precondition.

getShutdownEmbeddedDerby

public boolean getShutdownEmbeddedDerby()

setShutdownEmbeddedDerby

public void setShutdownEmbeddedDerby(boolean shutdown)

supportsSequences

public boolean supportsSequences()

Description copied from class: AbstractJdbcDatabase

Does the database type support sequence.

Specified by:

supportsSequences in interface Database

Overrides:

supportsSequences in class AbstractJdbcDatabase

supportsInitiallyDeferrableColumns

public boolean supportsInitiallyDeferrableColumns()

Description copied from interface: Database

Returns whether this database support initially deferrable columns.

getDateLiteral

public String getDateLiteral(String isoDate)

Description copied from class: AbstractJdbcDatabase

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

Note: many databases accept date literals in ISO8601 format with the 'T' replaced with a space. Only databases which do not accept these strings should need to override this method.

Implementation restriction: Currently, only the following subsets of ISO8601 are supported: yyyy-MM-dd hh:mm:ss yyyy-MM-ddThh:mm:ss

Specified by:

getDateLiteral in interface Database

Overrides:

getDateLiteral in class AbstractJdbcDatabase

supportsTablespaces

public boolean supportsTablespaces()

public String getViewDefinition(CatalogAndSchema schema,
 String name)
                         throws DatabaseException

Specified by:

getViewDefinition in interface Database

Overrides:

getViewDefinition in class AbstractJdbcDatabase

Throws:

DatabaseException

close

public void close()
           throws DatabaseException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Database

Overrides:

Overrides:

getMaxFractionalDigitsForTimestamp in class AbstractJdbcDatabase

Returns:

the maximum number of supported fractional digits in TIMESTAMP columns
