Dinamiškai generuoti SQL ne sprendimas?

int cc = rs.getMetaData().getColumnCount();
for ( i = 1 ; i <= cc  ; i++){
    if ( contains( rs.getMetaData().getColumnName(i), "A" ) ) {
        fields = fields +  rs.getMetaData().getColumnName(i);
        if (i < cc) { fields = fields + ","};
    }
   }
sql = 'select '+fields +'from lentute
