Question

我无法弄清楚为什么我的代码没有结果：

<Query Name="getClubPoints" RowName="Points">
    <SQL>
        <![CDATA[
            SELECT FirstName, LastName, ClubPoints
            FROM Customer
            WHERE CustomerID = '78520'
        ]]>
    </SQL>
</Query>

<PackageTransform>
    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:aspdnsf="urn:aspdnsf" exclude-result-prefixes="aspdnsf">
    <xsl:output method="html" omit-xml-declaration="yes"/>

        <xsl:template match="/">
            <xsl:if test="/root/System/CustomerIsRegistered='true'">
                <!--Customer is registered-->
                [<xsl:value-of select="/root/System/CustomerID" />] <xsl:value-of select="concat('Welcome, ',/root/System/CustomerFirstName)"/>!<br />
                You have [<xsl:value-of select="ClubPoints" />] Club Points 
            </xsl:if>
        </xsl:template>

    </xsl:stylesheet>
</PackageTransform>

此用户（我）拥有284点积分。此外，一旦我完成这项工作，我如何用变量替换78520以获取当前登录用户的ID？

这将检查运行时参数，并将SQL查询中的占位符“@customer”替换为当前客户的ID。另请参阅：http://manual.aspdotnetstorefront.com/p-157-xml-packages.aspx

<Query Name="getClubPoints" RowName="Points">
    <SQL>
        <![CDATA[
            SELECT FirstName, LastName, ClubPoints
            FROM Customer
            WHERE CustomerID = @customer
        ]]>
    </SQL>
    <queryparam paramname="@customer" paramtype="runtime" requestparamname="CustomerID" sqlDataType="int" defvalue="0" validationpattern="" />
</Query>
