嗨我有一個listView,我用SQLDataSource生成,Sql從URL獲取2個參數,然後執行Select Query。測試url參數的值,然後從代碼後面更改SqlDataSource.SelectCommand#
但我要測試的參數,第一個,然後更改SQL值的SelectCommand使用如果,否則,如果
問題是我的IF語句總是失敗,甚至當我刪除和更改在頁面加載查詢,我總是會返回使用SQLDataSource生成的原始數據,即使刪除了selectCommand也是如此!
這裏是我的ASPX文件
<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>
這裏的一部分,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;
}
}
任何想法,我做錯了什麼?
剛剛嘗試過,但我得到一個空或全空文本謂詞錯誤 –
這確實工作,這是我的SQL是錯的:-)謝謝 –
