Class PostgreSQLQuotedIDFactory

java.lang.Object

it.unibz.inf.ontop.dbschema.impl.PostgreSQLQuotedIDFactory

All Implemented Interfaces:

it.unibz.inf.ontop.dbschema.QuotedIDFactory

public class PostgreSQLQuotedIDFactory
extends Object
implements it.unibz.inf.ontop.dbschema.QuotedIDFactory

Creates QuotedIdentifiers following the rules of PostrgeSQL:
- unquoted identifiers are converted into lower case
- quoted identifiers are preserved PostgreSQL ---------- http://www.postgresql.org/docs/9.1/static/sql-syntax-lexical.html Unquoted names are always folded to lower (!) case. Quoted identifier is formed by enclosing an arbitrary sequence of characters in double-quotes ("). (To include a double quote, write two double quotes.) A variant of quoted identifiers allows including escaped Unicode characters identified by their code points. This variant starts with U& (upper or lower case U followed by ampersand) immediately before the opening double quote, without any spaces in between, for example U&"foo".
