Method Details

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()

getDefaultPort

public Integer getDefaultPort()

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

supportsCatalogs

public boolean supportsCatalogs()

Description copied from interface: Database

supportsInitiallyDeferrableColumns

public boolean supportsInitiallyDeferrableColumns()

Description copied from interface: Database

Returns whether this database support initially deferrable columns.

getDateLiteral

public String getDateLiteral(String isoDate)

Return an DB2 date literal with the same value as a string formatted using ISO 8601.

Convert an ISO8601 date string to one of the following results: to_date('1995-05-23', 'YYYY-MM-DD') to_date('1995-05-23 09:23:59', 'YYYY-MM-DD HH24:MI:SS')
