SQL Portability - SQL Dialects
 
 
- Most people are familiar with how to portably quote a string literal:
- It’s now also possible to portably quote identifiers like table names:
- 
$dbh->quote_identifier($name1, $name2, $name3, \%attr)
 
 For example:- 
$dbh->quote_identifier( undef, 'Her schema', 'My table' );
 
 using DBD::Oracle:		"Her schema"."My table”
 using DBD::mysql:		`Her schema`.`My table`
 
 
- If three names are supplied then the first is assumed to be a catalog name and special rules may be applied based on what get_info() returns for SQL_CATALOG_NAME_SEPARATOR and SQL_CATALOG_LOCATION.  For example:
- 
$dbh->quote_identifier( ’link’, ’schema’, ’table’ );
 
 using DBD::Oracle:		"schema"."table"@"link"
