我在我的數據庫中有一個名爲BalanceOnDate的準備語句，當我嘗試從下面的方法調用它時，出現以下錯誤，我盡力弄清楚了但我沒有看到任何線索的解決方案，請協助我，如何在java中正確調用預處理語句
public void fillClosingMontBalance(Month closingMonth) throws Exception {
Connection con = connection;
CallableStatement csForPreMonth = (CallableStatement) connection.prepareCall("{call BalanceOnDate(?,?,?)}");
for (Iterator i = ledgerList.iterator(); i.hasNext();) {
Ledger ledger = (Ledger) i.next();
csForPreMonth.setString(1, "St_" + ledger.getStockType());
csForPreMonth.setString(2, ledger.getFullLedgerNo());
csForPreMonth.setString(3, closingMonth.getFullDate());
ResultSet curRs = csForPreMonth.executeQuery();
curRs.last();
MonthEndBalance endBalance = new MonthEndBalance(curRs.getString("itmTyp"), curRs.getString("fulItmCode"),
curRs.getDouble("op_Balance"), curRs.getDouble("balance"), curRs.getDouble("total_received"),
curRs.getDouble("total_issued"), curRs.getString("unit"), curRs.getString("batchNo"),
curRs.getDouble("rawPrice"), curRs.getDouble("avg_unit_price"), curRs.getDate("sysDateTime"),
curRs.getString("facCode"), curRs.getString("comCode"), curRs.getString("fullLedgerNo"),
curRs.getString("stockType"), curRs.getString("fullItemName"));
closingMonthRecords.add(endBalance);
}
}
錯誤;

FUNCTION BalanceOnDate不存在的部分不清楚嗎？它告訴你名爲'BalanceOnDate'的數據庫中的存儲過程沒有被定義。要麼它不存在，要麼處於不同的模式中，並且名稱需要使用模式進行限定。 – 2012-02-02 02:49:09
