我有一个奇怪的错误。我用java和derby数据库编写了一个应用程序。所以我使用这个应用程序1年，但是从3天开始我尝试执行查询以提取数据时出现此错误，但我没有更改代码。 如果我尝试为选择数据执行所有方法，则会出现此错误：

这是我用于从数据库中选择数据的方法之一：
public Vector estraiMesiEAnno(String tipoTabella) {
String query ="";
if(tipoTabella.equalsIgnoreCase("STORICO")){
query = "SELECT month(data) AS MESE, YEAR(DATA) AS ANNO FROM CODSCONTRINI_STORICO GROUP BY MONTH(DATA), YEAR(DATA)";
}else if(tipoTabella.equalsIgnoreCase("OPERATIVA")){
query = "SELECT month(data) AS MESE, YEAR(DATA) AS ANNO FROM CODSCONTRINI GROUP BY MONTH(DATA), YEAR(DATA)";
}
Vector v = null;
int colonne = 0;
try {
PreparedStatement stmt = db.prepareStatement(query); // Creo lo Statement per l'esecuzione della query
ResultSet rs = stmt.executeQuery(); // Ottengo il ResultSet dell'esecuzione della query
v = new Vector();
ResultSetMetaData rsmd = rs.getMetaData();
colonne = rsmd.getColumnCount();
while(rs.next()) { // Creo il vettore risultato scorrendo tutto il ResultSet
Vector record = new Vector();
for (int i=0; i<colonne; i++) {
record.add(rs.getString(i+1));
}
v.add(record);
}
rs.close(); // Chiudo il ResultSet
stmt.close(); // Chiudo lo Statement
} catch (Exception e) {
log.logStackTrace(e);
VisualMessage.getErroreDB();
}
return v;
}

数据库本身已经受到物理损坏。可悲的是，USB闪存驱动器不会永远存在。
您是否在任何地方备份数据库？
