嗨,我有一个使用 SQLDataSource 生成的 listView,Sql 从 URL 获取 2 个参数,然后执行 Select Query。
但我想测试参数 1st 的值,然后使用 If 更改 sql SelectCommand,否则如果
问题是我的 IF 语句总是失败,即使我删除它们并在页面加载时更改查询,即使删除了 selectCommand,我也总是返回使用 SQLDataSource 生成的原始数据!
这是我的 ASPX 文件的一部分
<asp:SqlDataSource ID="jobSearch" runat="server" ConnectionString="<%$ ConnectionStrings:DefaultConnection %>" SelectCommand="">
<SelectParameters>
<asp:QueryStringParameter Name="jobTitle" QueryStringField="jobTitle" Type="String" />
<asp:QueryStringParameter Name="joblocation" QueryStringField="jobLocation" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
这是我的 .CS 文件
protected void Page_Load(object sender, EventArgs e)
{
// Request.QueryString["jobTitle"]
string jobTitle = Request.QueryString["jobTitle"];
string jobLocation = Request.QueryString["jobLocation"];
if (!string.IsNullOrEmpty(jobTitle) && !string.IsNullOrEmpty(jobLocation))
{
jobSearch.SelectCommand = "SELECT [jobId], [userId], [jobTitle], [jobBody], [jobPosition], [JobType], [salaryFrom], [salaryTo], [salaryType], [location], [jobCreated], [jobEnd], [jobViews], [applications] FROM [recruiter_Jobs] WHERE FREETEXT (([jobTitle]), @jobTitle) AND FREETEXT (([location]), @location) ORDER BY [jobCreated]";
test.Text = "1st if " + jobTitle;
}
else if (jobTitle == string.Empty && !string.IsNullOrEmpty(jobLocation) || string.IsNullOrWhiteSpace(jobTitle) && !string.IsNullOrEmpty(jobLocation) || string.IsNullOrEmpty(jobTitle) && !string.IsNullOrEmpty(jobLocation) || jobTitle == null && !string.IsNullOrEmpty(jobLocation))
{
jobSearch.SelectCommand = "SELECT [jobId], [userId], [jobTitle], [jobBody], [jobPosition], [JobType], [salaryFrom], [salaryTo], [salaryType], [location], [jobCreated], [jobEnd], [jobViews], [applications] FROM [recruiter_Jobs] WHERE FREETEXT (([location]), @location) ORDER BY [jobCreated]";
test.Text = "1st else if " + jobTitle;
}
else if (string.IsNullOrEmpty(jobTitle) && string.IsNullOrEmpty(jobLocation))
{
jobSearch.SelectCommand = "SELECT [jobId], [userId], [jobTitle], [jobBody], [jobPosition], [JobType], [salaryFrom], [salaryTo], [salaryType], [location], [jobCreated], [jobEnd], [jobViews], [applications] FROM [recruiter_Jobs] ORDER BY [jobCreated]";
test.Text = "last else if " + jobTitle;
}
}
知道我做错了什么吗?
