我的查询

UPDATE TOP (1) TX_Master_PCBA  
SET TIMESTAMP2 = '2013-12-12 15:40:31.593'
WHERE SERIAL_NO IN ('0500030309') 
ORDER BY TIMESTAMP2 DESC 

使用表中的serial_No列TX_Master_PCBA我有10条记录,但我想更新最新TIMESTAMP2的当前日期时间.

上面的查询抛出错误:

关键字"TOP"附近的语法不正确.

我使用以下代码滑块

Css和Jquery:

<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.js"></script> 
<script type="text/javascript" src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>

ASPX:

<p>
   <label for="amount">Value:</label> 
   <input type="text" id="amount" style="border: 0; color: #f6931f; font-weight: bold;" />%
</p> 
<div id="slider-vertical" style="height: 15px; width:800px"></div>
<script type="text/javascript">
    $(function () {
        $("#slider-vertical").slider({
            orientation: "horizantal", range: "min", min: 0, max: 100, value: 60,
            slide: function (event, ui)
            { $("#amount").val(ui.value); }
        });
        $("#amount").val($("#slider-vertical").slider("value"));
    });
</script>

我正在尝试设置滑块的值:

function UpdateSlider(PhaseInStatusReportVal) {
    $("#slider-vertical").slider("value").val(PhaseInStatusReportVal);
}

我在上面调用代码来代码:

ClientScript.RegisterStartupScript(Me.GetType(), "updatetheslider", "UpdateSlider('" + BCOMSPackageValidationList(0).PhaseInStatusReport.ToString() + "')", True)

但它抛出了上述错误.

谁能帮帮我吗？

当我在Include Actual Execution Plan中运行以下查询时,我有一个查询,然后它会抛出以下错误:

执行结果:

(1排受影响)

(89排受影响)

(1行受影响)消息262,级别14,状态4,行25 SHOWPLAN权限在数据库'tempdb'中被拒绝.

注意:在temptables上创建CLUSTERED INDEX之前它工作正常.在创建CLUSTERED INDEX之后,它显示出上述错误.如何查看以下查询的执行计划任何建议.

如何验证作为哈希值存储在数据库中的密码

当我使用数据库值验证密码哈希时，它永远不会相同，因为它会生成随机盐。

如何添加盐以进行验证和测试。

下面是我用于散列和验证散列密码的代码。

我的代码：

/// <summary>
        /// Generate the value from bytes.
        /// </summary>
        /// <param name="password"></param>
        /// <param name="iterationCount"></param>
        /// <returns></returns>
        private static string GenerateHashValue(string password)
        {
            return Convert.ToBase64String(GenerateHashBytes(password));
        }

        /// <summary>
        /// Hashing the password using PBKDF2
        /// </summary>
        /// <param name="password"></param>
        /// <param name="iterationCount"></param>
        /// <returns></returns>
        private static byte[] GenerateHashBytes(string password)
        {
            byte[] hashValue;
            //create salt
            byte[] salt = GenerateRandomSalt();
            var valueToHash = string.IsNullOrEmpty(password) ? string.Empty : password;
            using (var pbkdf2 = new Rfc2898DeriveBytes(valueToHash,salt, iterationCount))
            { …

我有VB.NET代码用于将驱动器映射到网络路径.

strPath = "\\11.22.33.11\Hostsw\Host\SW\"  

当我MapDrive("T", strpath, "pcs", "$pcspcs$")使用以下功能调用时,它会显示错误消息"Bad path could not connect to Star Directory".
