Constructor Detail

InformixDatabase

public InformixDatabase()

Method Detail

getSystemTablesAndViews

protected Set<String> getSystemTablesAndViews()

Description copied from class: AbstractDatabase

Returns system (undroppable) tables and views.

Overrides:

getSystemTablesAndViews in class AbstractDatabase

getPriority

public int getPriority()

setConnection

public void setConnection(DatabaseConnection connection)

Specified by:

setConnection in interface Database

Overrides:

setConnection in class AbstractDatabase

getCurrentDateTimeFunction

public String getCurrentDateTimeFunction()

Description copied from interface: Database

Returns database-specific function for generating the current date/time.

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.

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.

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

supportsInitiallyDeferrableColumns

public boolean supportsInitiallyDeferrableColumns()

Description copied from interface: Database

Returns whether this database support initially deferrable columns.

supportsTablespaces

public boolean supportsTablespaces()

getViewDefinition

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

Specified by:

getViewDefinition in interface Database

Overrides:

getViewDefinition in class AbstractDatabase

Throws:

DatabaseException

getAutoIncrementClause

public String getAutoIncrementClause()

Description copied from class: AbstractDatabase

Returns database-specific auto-increment DDL clause.

Specified by:

getAutoIncrementClause in interface Database

Overrides:

getAutoIncrementClause 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

public boolean supportsRestrictForeignKeys()

Specified by:

supportsRestrictForeignKeys in interface Database

Overrides:

supportsRestrictForeignKeys in class AbstractDatabase

supportsSchemas

public boolean supportsSchemas()

Specified by:

supportsSchemas in interface Database

Overrides:

supportsSchemas in class AbstractDatabase
