question: private static String printSchema ( StringBuilder sb , String schema , String lastSchema , boolean pureSQL ) { if ( schema != null && ( lastSchema == null || ( lastSchema != null && lastSchema . compareTo ( schema ) != 0 ) ) ) { if ( pureSQL ) { if ( schema . length ( ) > 0 ) println ( sb , "USE " + schema + ";" ) ; } else println ( sb , "- SCHEMA = " + schema ) ; } return schema ; }
target:  Format and print schema name if it differs from the last printed schema name.
