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.


getDefaultPort

public Integer getDefaultPort()

getDefaultDatabaseProductName

protected String getDefaultDatabaseProductName()
Specified by:
getDefaultDatabaseProductName in class AbstractJdbcDatabase

getPriority

public int getPriority()

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.


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

supportsDefaultValueComputed

public static boolean supportsDefaultValueComputed(String columnType,
                                                   String defaultValue)
Checks to see if the string is an acceptable computed value for HSQL "datetime" columns are the only columns for which HSQL supports computer values.

Parameters:
columnType - String of the column's data type
defaultValue - String to be checked for valid valueComputed in HSQL
Returns:
boolean True if the string represents a function supported by HSQL for default values

supportsInitiallyDeferrableColumns

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


supportsCatalogs

public boolean supportsCatalogs()
Specified by:
supportsCatalogs in interface Database
Overrides:
supportsCatalogs in class AbstractJdbcDatabase

getConnectionCatalogName

protected String getConnectionCatalogName()
                                   throws DatabaseException
Overrides:
getConnectionCatalogName in class AbstractJdbcDatabase
Throws:
DatabaseException

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

parseDate

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

supportsTablespaces

public boolean supportsTablespaces()

isReservedWord

public boolean isReservedWord(String value)
Specified by:
isReservedWord in interface Database
Overrides:
isReservedWord in class AbstractJdbcDatabase

isCaseSensitive

public boolean isCaseSensitive()
Specified by:
isCaseSensitive in interface Database
Overrides:
isCaseSensitive in class AbstractJdbcDatabase

setConnection

public void setConnection(DatabaseConnection conn)
Specified by:
setConnection in interface Database
Overrides:
setConnection in class AbstractJdbcDatabase

isUsingOracleSyntax

public boolean isUsingOracleSyntax()

escapeObjectName

public String escapeObjectName(String objectName,
                               Class<? extends DatabaseObject> objectType)
Specified by:
