HsqlDatabase

public HsqlDatabase()
Method Detail

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()

getTypeName

public String getTypeName()
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.


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

supportsInitiallyDeferrableColumns

public boolean supportsInitiallyDeferrableColumns()
Description copied from interface: Database
Returns whether this database support initially deferrable columns.


getDefaultDatabaseSchemaName

protected String getDefaultDatabaseSchemaName()
                                       throws DatabaseException
Overrides:
getDefaultDatabaseSchemaName in class AbstractDatabase
Throws:
DatabaseException

getCurrentDateTimeFunction

public String getCurrentDateTimeFunction()
Description copied from interface: Database
Returns database-specific function for generating the current date/time.


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 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.

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 AbstractDatabase

parseDate

public Date parseDate(String dateAsString)
               throws DateParseException
Specified by:
parseDate in interface Database
Overrides:
parseDate in class AbstractDatabase
Throws:
DateParseException

supportsTablespaces

public boolean supportsTablespaces()

convertRequestedSchemaToSchema

public String convertRequestedSchemaToSchema(String requestedSchema)
                                      throws DatabaseException
Specified by:
convertRequestedSchemaToSchema in interface Database
Overrides:
convertRequestedSchemaToSchema in class AbstractDatabase
Throws:
DatabaseException

escapeDatabaseObject

public String escapeDatabaseObject(String objectName)
Specified by:
escapeDatabaseObject in interface Database
