执行存储过程时出错

Question

我写了一个调用过程，但是抛出了一个异常，请你看看我的代码：

try 
{   
    connection myconn = Database.Get_Connection();
    CallableStatement mystmt =null;
    mystmt = myconn.prepareCall("{? =call proc_hi_check_user(?,?)}");
    mystmt.setString(1,name);
    mystmt.setString(2,"");
    mystmt.execute();
    param1 = mystmt.getInt(1);
    ResultSet myrs = mystmt.getResultSet();
    while(myrs.next())
    {
        System.out.println("inside");
        System.out.println(myrs.getInt(1));
        //result=myrs.getString(1);
    }
} catch (Exception e)
{
    System.out.println("db connection not connected");
}

Answer 1

从您在评论中所说的来看，您似乎缺少一个 sql 函数“proc_pandu_check_user”。

检查“proc_hi_check_user”的主体，它应该在某个地方调用这个 proc_pandu_check_user 并且它可能丢失或有错误的参数列表。

尝试执行以下代码：

try 
{   
    connection myconn = Database.Get_Connection();
    CallableStatement mystmt =null;
    mystmt = myconn.prepareCall("{? =call proc_hi_check_user(?,?)}");
    mystmt.registerOutParameter(1, java.sql.Types.OTHER);
    mystmt.setString(2,name);
    mystmt.setString(3,"");
    mystmt.execute();
    param1 = mystmt.getInt(1);
    ResultSet myrs = mystmt.getResultSet();
    while(myrs.next())
    {
        System.out.println("inside");
        System.out.println(myrs.getInt(1));
        //result=myrs.getString(1);
    }
} catch (Exception e)
{
    System.out.println("db connection not connected");
}
