我試圖CallableStatement的程序在數據庫執行罰款，但 arrayindex出界錯誤的SQL工具類，是我讓我嘗試調試它似乎有些不妥CallableStatement的

的語法

public int CalableStatement(String query,Login login,String type) throws ClassNotFoundException, SQLException 
{ int i =0; 
    try { 
    Connection con = getConnection(); 
    //String q = query+"(?,?,?)"; 
    CallableStatement cst = con.prepareCall("call loginPlan_k(?,?,?)"); 

    //Login login = null ; 
    //String type=lassType.getType(); 
    /*if(type.equals("login")) 
    { 
     login = (Login)o; 
    }*/ 
    System.out.println(login.getUserName()+"DataAccess"); 
    cst.setString(1, login.getUserName()); 
    cst.setString(2, login.getPassword()); 
    cst.registerOutParameter(3,java.sql.Types.INTEGER); 

    ResultSet rs = cst.executeQuery(query); 
    if(rs.next()) 
    { i = cst.getInt(1);} 
}catch (Exception e) { 
    // TODO: handle exception 
    e.printStackTrace(); 
} 
    return i ; 


} 


} 

這是錯誤，我收到

Answer 1

沒有第三個參數，但一些奇怪的文字@result。用問號替換它。

CallableStatement cst = con.prepareCall("{call loginPlan_k(?,?,?)}"); 

爲Oracle見樣品：http://www.literak.cz/2013/08/working-with-complex-database-types-in-weblogic/

Answer 2

輸出參數應該由一個佔位符，因爲它們是用於將輸入的參數來表示。你也需要在大括號{}

CallableStatement cst = con.prepareCall("{call loginPlan_k(?,?,?)}");
