使用pwdencrypt时从哪里登录？

Question

我试图通过我的程序登录我们的数据库,但是当我这样做时,我得到无效的凭证,所以我不知道从哪里开始希望任何人都可以帮助我,因为我之前没有使用过pwdencryp和pwdcompare而且我不是确定如何让它发挥作用

我的代码:

       protected String doInBackground(String... params) {
            if (userid.trim().equals("Developer")|| password.trim().equals("Dev!n_234"))
                isSuccess2=true;
            z = getString(R.string.login_succes);
            if(userid.trim().equals("")|| password.trim().equals(""))
                z = getString(R.string.indsæt_rigtigt_bruger);
            else
            {
                try {
                    Connection con = connectionClass.CONN();
                    if (con == null) {
                        z = getString(R.string.Forbindelses_fejl)+"L1)";

                    } else {
                        CallableStatement cs = null;
                        String query = "{call [system].[usp_validateUserLogin] (?,?,?,?,?)}";
                        Statement stmt = con.createStatement();
                        ResultSet rs = stmt.executeQuery(query);
                        CallableStatement ps = con.prepareCall(query);
                        ps.setString(1, userid);
                        ps.setString(2, password);
                        ps.setInt(3,72);
                        ps.setNull(4, Types.BOOLEAN);
                        ps.registerOutParameter(5, Types.VARCHAR);
                        cs.executeUpdate();
                        if(rs.next())
                        {

                            z = getString(R.string.login_succes);

                            isSuccess=true;
                        }
                        else
                        {
                            z = getString(R.string.Invalid_Credentials);
                            isSuccess = false;
                        }

                    }
                }
                catch (Exception ex)
                {
                    isSuccess = false;
                    z = getString(R.string.Exceptions)+"L2)";
                    Log.e("MYAPP", "exception", ex);
                }
            }
            return z;

        }
    }


}

在过程 [usp_validateUserLogin] 中，您使用参数 @p_OutDetails 来确定是否将数据返回给调用者，而在调用者中，您使用记录已返回的事实来确定该过程是否成功。

该行将ps.setString(4, null);[usp_validateUserLogin] 中的参数 @p_OutDetails 的值设置为 null。这与根本不提供参数不同，因为 SQL Server 将使用值 NULL 而不是默认值。如果未提供该参数，则它将使用默认值 (1)。此外，预期的参数类型是 BIT，因此应该使用 ps.SetBoolean 之类的东西将 BIT 参数的值设置为显式值 1（或 true）。

作为显示使用默认值与提供 NULL 值的示例：

CREATE PROCEDURE TestProc
    @MyString   VARCHAR(10) = 'string'

AS
BEGIN
    SET NOCOUNT ON
    SELECT @MyString AS Param, ISNULL(@MyString, 'Was Null') AS ItsValue
END
GO


EXEC TestProc null
EXEC TestProc 'A Value'
EXEC TestProc   --no params at all

运行此过程会为 3 种类型的 EXEC 返回以下内容。

Param,ItsValue
NULL,Was Null

Param,ItsValue
A Value,A Value

Param,ItsValue
string,string

您的代码正在执行第一种方式，因此当它执行以下行时，@p_OutDetails 包含 NULL 并且它会跳过此位。

IF ( @p_OutDetails = 1 )
BEGIN
    SELECT *
    FROM #tmpLogin
END
