Way To Make Database Field A DateTime Field To String
Oct 5, 2010
Dim query as String = "Select * from openquery (devbook, 'SELECT wb.arrival_time FROM web_bookings wb ')"All I need is to convert my arrival_time into a datetime field in the query
i am implementing a update query module.i am displaying all fields from a table for a term searched. well now i am implementing update option for the record which are displayed, i have like 70 columns in my table, and i want to know how to restrict some selected fields to be only read only while the form can be updated ?Like if user select to update a record then some selected field such as "Timestamp, UID etc some selected fields" remains READ ONLY !
I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
This code works fine if i use this inside ssercontrol > panel and i have a checkboxes in table when no checkbox is checked its works fine .... but if i disabled and checked any of the textbox then this doesn't work .... in usercontrol why ? i didnt understand ..
<script type="text/javascript" language="javascript"> function checkboxChecked(){ var allInputs = document.getElementsByTagName("input"); for(var i=0; i<allInputs.length; i++) { var chk = allInputs[i]; if(chk.type == "checkbox" && !chk.disabled && chk.checked) {
return true; } } alert("OOps! You haven't selected all available checkboxes"); return false; } </script>
I retrieve the date & time from datetime field in sql using a reader:
[Code]....
This value returns e.g. 15/04/2010 8:00:00 but I would like to split the day value (15), month value (4) etc from the overall datetime value, so I can assign dropdowns with corresponding (preselected) day, hour selection ..I know the dropdown assignment process, but I can't get the datetime field/value split ..
I'm having a problem understanding how to use TextBoxFor with a DateTime field (in particular how to add htmlAttributes). MVC has helpfully scaffolded the following for me:
[Code]....
I now want to add an htmlAttribute to this, to make the rendered <input> element read-only, for example: new {@readonly="true"} The problem I have, is that the MSDN documentation for TextBoxFor (see [URL] says only allows two arguments are allowed, the LINQ expression, and a dictionary or object containing the htmlAttributes. So I have two questions:
1. What is the role of "String.Format("{0:g}", Model.LastPolled)" in the scaffolded version? This obviously works, but doesn't seem to be an htmlAttribute.
2. How should I modify the scaffolded version so that the readonly attribute will be used?
I am using and EntityDateSource and I add where condition to filter the data at runtime and then bind the grid to the dataSource, but I am getting following error:-
The argument types 'Edm.DateTime' and 'Edm.String' are incompatible for this operation.
I want to fetch date from a datetime field, when i select this field in database i get the result as 'yyyy-mm-dd hh:mm:ss' i want the result to be like dd/mm/yyyy
I am developing website using ASP.net C# using Mysql.query i have made is:
//***to get next date string nextdatequery = "SELECT next_dt FROM testcase.heardt where fil_no=? and next_dt>?;";
how do i display a datefield field e.g. 07/27/2010 08:00:00 as Tuesday, July 27, 2010? (i want the time part but i couldnt find any fucntions that display the date in text mode?)
I am creating a SQL procedure and need to read the data back into a gridview in that format.
I have a textbox that I use to gather a date. I would like to have the database store a null if this field is left blank by the user when submitting. I am using the following on my aspx page:
I'm looping through an ArrayList and creating a column in a DataTable from each field. One of my fields is a DateTime field, and I've noticed that when I create the columns, it's being changed to a String, but I need it to still be a DateTime field for sorting. I'm trying to do this, but it's not quite working.
how do i insert date and time together ? what is the format for this. i tried like this but its not working.
string startDtime = TextFromDate.Text + " " + Stime; sql_comm.Parameters.AddWithValue("@StartDate", DateTime.Parse(startDtime)); is this the right way ? dd/mm/yyy +" "+ 00:00 or i need to make a string that contain this : dd/mm/yyy00:00 its not writing any eror it just do nothing .
I have a date field in a typed dataset that created from database.
I get an NULL Value exception when I try to enter some null value. I am not able to set the Nullvalue property of the DateTime field in XSD to other value other than Throw Exception.
I need to format this date time into the format Day/Month/Year on the same template field.
I am avoiding doing this under SQL server because that will mean changing my data type in my dataset to string instead of data time which i do not want.
I have trouble of saving "no time" to a datetime field in my db by using objectdatasource.I am using a formview to insert new record by an insert method in an objectdatasource.
