Constructor Detail

H2Database

public H2Database()

Method Detail

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.

getDefaultPort

public Integer getDefaultPort()

getDefaultDatabaseProductName

protected String getDefaultDatabaseProductName()

Specified by:

getDefaultDatabaseProductName in class AbstractJdbcDatabase

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()

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(CatalogAndSchema schema,
                                String name)
                         throws DatabaseException

Specified by:

getViewDefinition in interface Database

Overrides:

getViewDefinition in class AbstractJdbcDatabase

Throws:

DatabaseException

parseDate

public Date parseDate(String dateAsString)
               throws DateParseException

Specified by:

parseDate in interface Database

Overrides:

parseDate in class AbstractJdbcDatabase

Throws:

DateParseException

isSafeToRunUpdate

public boolean isSafeToRunUpdate()
                          throws DatabaseException

Description copied from class: AbstractJdbcDatabase

Default implementation, just look for "local" IPs. If the database returns a null URL we return false since we don't know it's safe to run the update.

Specified by:

isSafeToRunUpdate in interface Database

Overrides:

isSafeToRunUpdate in class AbstractJdbcDatabase

Throws:

DatabaseException

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

getConnectionSchemaName

protected String getConnectionSchemaName()

Description copied from class: AbstractJdbcDatabase

Overwrite this method to get the default schema name for the connection. If you only need to change the statement that obtains the current schema then override

Overrides:

getConnectionSchemaName in class AbstractJdbcDatabase

Returns:

See Also:

AbstractJdbcDatabase.getConnectionSchemaNameCallStatement()

getConcatSql

public String getConcatSql(String... values)

Description copied from interface: Database

Returns SQL to concat the passed values.

Specified by:

getConcatSql in interface Database

Overrides:

getConcatSql in class AbstractJdbcDatabase

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

isReservedWord

public boolean isReservedWord(String objectName)

Specified by:

isReservedWord in interface Database

Overrides:

isReservedWord in class AbstractJdbcDatabase

supportsInitiallyDeferrableColumns

public boolean supportsInitiallyDeferrableColumns()

Description copied from interface: Database

Returns whether this database support initially deferrable columns.

protected String getAutoIncrementClause()

Overrides:

getAutoIncrementClause in class AbstractJdbcDatabase

getAutoIncrementStartWithClause

protected String getAutoIncrementStartWithClause()

Overrides:

getAutoIncrementStartWithClause in class AbstractJdbcDatabase

getAutoIncrementByClause

protected String getAutoIncrementByClause()

Overrides:

getAutoIncrementByClause in class AbstractJdbcDatabase

public boolean createsIndexesForForeignKeys()

Specified by:

createsIndexesForForeignKeys in interface Database

Overrides:
