我有一张像这样的桌子:
DECLARE @deadCommunityList TABLE (community VARCHAR(12))
INSERT INTO @deadCommunityList (community)
VALUES ('000')
, ('253'), ('COU'), ('COV')
, ('D2T'), ('D3T'), ('DEW')
, ('DIT'), ('E2T'), ('E3T')
, ('EL2'), ('EL3'), ('ELC')
, ('ELI'), ('ELT'), ('ERI')
, ('FA1'), ('GRA'), ('GRD')
, ('GRT'), ('HIG'), ('HIP')
, ('LYN'), ('NEW'), ('PAR')
, ('PMT'), ('RDT'), ('RES')
, ('SCR'), ('SCT'), ('SMT')
, ('SUM'), ('TB'), ('W2T')
, ('WDV'), ('WE2'), ('WIC')
, ('WEC'), ('WIL'), ('ZIT')
现在我有这样的查询:
SELECT DISTINCT AREA_DESC
FROM V_CONSTAT_PROJ_DATES
WHERE AREA_ID NOT IN @deadCommunityList
ORDER BY AREA_DESC
我想说的是给我结果,其中AREA_ID不在表中....这不起作用,我得到以下错误:
必须声明标量变量"@deadCommunityList". …
我有一个这样的提交按钮:
<input type="submit" value="Submit" id="submitButton" />
我也有这个awesomefont图标
<i class="fa fa-search"></i>
我尝试将类添加到提交按钮,但这不起作用.
我有这行代码：
ROW_NUMBER() OVER (ORDER BY V_CONSTAT_ACTUAL_DATES.DATE_TO_END) AS SortOrder
但这从 1 开始......我如何让它从 0 开始？
我试过了，ROW_NUMBER() - 1但这没有用。我也尝试过，1 - ROW_NUMBER()但这给了我 0 然后是 -1。
我正在使用ASP.NET MVC 5实体框架.在我的视图中,我有一个下拉菜单,我想要做的是使用枚举来填充下拉菜单.这就是我在课堂上得到的:
public enum occupancyTimelineTypes : int
{
TwelveMonths = 12,
FourteenMonths = 14,
SixteenMonths = 16,
EighteenMonths = 18
}
还有这个:
[DisplayName("Occupancy Timeline")]
[Required]
public string occupancyTimeline { get; set; }
public occupancyTimelineTypes occupancyTimelineType
{
get
{
return Enum.Parse(typeof(occupancyTimelineTypes), occupancyTimeline);
}
}
我的问题是,我收到一个错误,我不知道如何解决:
无法隐式地将类型"对象"转换为存在显式转换(您是否错过了转换？)
我正在填充我的下拉菜单:
@Html.DropDownListFor(model => model.occupancyTimeline,Model.occupancyTimelineType.ToSelectList());
这是我的ToSelectList()方法
public static class MyExtensions
{
public static SelectList ToSelectList(this occupancyTimelineTypes enumObj)
{
var values = from occupancyTimeline e in Enum.GetValues(typeof(occupancyTimeline))
select new { Id = e, Name …我在这里有这个代码:
<div style="border:3px solid #808080;">
<h1 style="text-transform: uppercase;font-size: 38px;color: #808080;text-align: center;">Lowell</h1>
<div class="column-1">
<img src="images/ruler-icon.png">
</div>
<div class="column-2">
<img src="images/bed-icon.png">
</div>
<div class="column-3">
<img src="images/bath-icon.png">
</div>
</div>
我的问题是边框没有越过第1列,第2列,第3列......那些元素是左边浮动的,我如何将它们包含在边框中？
这是CSS
.column-1, .column-2, .column-3
{
float:left;
width: 33%;
border-right: 3px solid #808080;
height: 52px;
padding: 10px;
}
我这个约会在这里:
DateTime RelevantDate = new DateTime(2017, 11, 13, 16, 0, 0, 0);
request.RelevantDate = Convert.ToDateTime(RelevantDate.ToString("o"));
我期待着:
2017-11-13T16:00:00-05:00
相反,我得到:
2017-11-13T16:00:00
这真的需要采用以下格式:2017-11-13T16:00:00-05:00,我该怎么做？request.RelevantDate期待DateTime
如果我这样做:
request.RelevantDate = Convert.ToDateTime(DateTime.Now.ToString("o"));
它给了我正确的格式:
2017-11-08T06:43:39-05:00
我正在尝试使用纯 CSS 进行连续滚动文本。
这是我试图滚动的 HTML：
<div class="marquee">
<div class="text">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas placerat maximus massa ut dictum. Sed eu est justo. Quisque pharetra vel tellus ac porttitor. Nunc luctus sollicitudin diam non dignissim. Phasellus mollis semper libero, nec rhoncus est tristique quis. Nulla eget pharetra nunc, sed faucibus felis. Curabitur nec posuere nisl. Quisque at vestibulum velit. Pellentesque sagittis lacus ut aliquet faucibus. Ut porta purus id mi tincidunt mollis. Integer vulputate, eros malesuada viverra …我试图在本地主机上运行现有的Laravel项目，但是当我尝试运行dam时，出现此错误：
流或文件“ /storage/logs/laravel.log”无法打开：打开流失败：权限被拒绝
我尝试了以下方法：
chmod -R 775 storage 和 chmod -R 777 storage
还是一无所获，我什至试图做，chgrp -R www-data my-project并且在终端中出现此错误
chgrp: www-data: illegal group name
我究竟做错了什么？
我有 UIBarButtonItem 并且选择器方法没有被调用，这让我发疯了好几天。
这些在我的 viewDidLoad 方法中
let doneButton = UIBarButtonItem(title: "Done", style: .plain, target: nil, action: #selector(self.doneButtonPressed))
self.navigationItem.rightBarButtonItem = doneButton
let cancelButton = UIBarButtonItem(title: "Cancel", style: .plain, target: nil, action: #selector(self.cancelButtonPressed))
self.navigationItem.leftBarButtonItem = cancelButton
方法如下：
@objc func doneButtonPressed()
{
dismiss(animated: true, completion: nil)
}
@objc func cancelButtonPressed()
{
dismiss(animated: true, completion: nil)
}
为什么他们没有被召唤？
我有这个数组,我做了一个print_r($ resultArray)并得到了这些结果;
Array ( [0] => Array ( [invoiceid] => 992 [client] => www [invoicedeliverymethod] => email [date] => 2011-11-04 [enddate] => 2011-10-31 23:59:59 [total] => 103.00 [remainingbalance] => 103.00 [ispaid] => No [isagentpaid] => No [datedistributed] => 2011-11-04 [invoicedcontact] => 1 ) [1] => Array ( [invoiceid] => 991 [client] => www [invoicedeliverymethod] => email [date] => 2011-11-04 [enddate] => 2011-09-30 23:59:59 [total] => 103.00 [remainingbalance] => 103.00 [ispaid] => No [isagentpaid] => No [datedistributed] => Not distributed [invoicedcontact] …
