I have a list of events that are shown on "Events" page using a repeater. Each event is a page type and has a field "EventStartDateTime". I want to show only those events where the event start date is >= today. For now in the WHERE field in repeater,i am using the following condition:
(EventStartDateTime >= '{% DateTime.Now #%}') OR (EventStartDateTime = '')
But no data is visible on the page. So is it right ?
Any help will be greatly appreciated. Thanks
I checked your code and it's kinda worked for me, but I will still modify it like this:
(EventStartDateTime >= GetDATE()) OR (EventStartDateTime IS NULL)
Because second part where you compare 'Date and time' field with empty string is not correct. So in your case, you don't get any data if 'EventStartDateTime' is not populated for every item. If that is not the case, you should try remove WHERE condition and check if you get data without it.
Best regards,

Your statement will work with a macro like so:
(EventStartDateTime >= '{% CurrentDateTime.ToShortDateString() %}')
Your second condition would not work because your EventStartDateTime field is (assumed) to be a DateTime object so checking for an empty string will not work. You need to check for NULL.

I have a custom field being added on user story (HierarchicalRequirement) level.
The WSAPI documentation shows the following details for the field:
c_CustomFieldName
Required false
Type string
Max Length 32,768
Sortable true
Explicit Fetch false
Query Expression Operators contains, !contains, =, !=
When trying to create a report using Custom List to identify user stories where this field is empty, I add (c_CustomFieldName = "") to the query.
And yet, the result shows rows where this field is not empty.
How can that be?
I tried querying on null, but it didn't work.
thx in advance
What you're doing should work- are you getting errors, or just incorrect data? It almost seems like it's ignoring your query altogether.
I tried to repro both with the custom list app and against wsapi directly and the following all worked as expected:
(c_CustomText = "") //empty
(c_CustomText = null) //empty
(c_CustomText != "") //non-empty
(c_CustomText != null) //non-empty
It's possible you're running into some weird data-specific edge case in your data. It may be worth following up with support.
How to Show date in textbox from database.TextBox type is "date". In asp.net
As the experts said above, this one worked for me:
((DateTime)dr["columnName"]).ToString("yyyy-MM-dd")
or
Convert.ToDateTime(dr["columnName"]).ToString("yyyy-MM-dd");
Try to re-format the date in the parentheses, it may be (yyyy-MM-dd) or (dd-MM-yyyy)
This one is working in 2023.
NOTE: I'm fetching the data from the database in a DataRow instead of DataTable, NOT because it works better, but because this is what I need.
You need to convert the value to a datetime, then convert again to string.
Something like this:
_txtCoatOrderDate.Text = ((Datetime)dt.Rows[i]["Coat_CUSTM_Date"]).ToString("dd/MM/yyyy");
Try this-
_txtCoatOrderDate.Text = Convert.ToDateTime(dt.Rows[i]["Coat_CUSTM_Date"]).ToString("dd/MM/yyyy");
i tried this its working
TextBox1.Text = ((DateTime)ds.Tables[0].Rows[0]["Coat_CUSTM_Date"]).ToString("yyyy-MM-dd");
Thanks RMH Sir
I've spent several hours going through StackOverflow and playing around with this query, but still can't get it to work! Hopefully an expert here on SO can make the pain go away...
I have two models, Event and EventInstance. An Event has_many EventInstances.
What I want to do is easily get a list of Events (not EventInstances), where:
Events are distinct and not repeated
Events are sorted by the start_date of the nearest EventInstance
Event instances have the attribute :active => true
Only event instances that have a start date in the future are returned
I currently have the query
Event.joins(:event_instances).select('distinct events.*').where('event_instances.start_date >= ?', Time.now).where('event_instances.active = true')
This returns a list of events, but not sorted by date. Excellent - so I am almost there!
If I change the query to add this on the end:
.order('event_instances.start_date')
I get the error:
PG::InvalidColumnReference: ERROR: for SELECT DISTINCT, ORDER BY expressions must appear in select list
So I moved it to the select statement:
select('distinct event_instances.start_date, events.*')
Now I get
PG::UndefinedFunction: ERROR: function count(date, events) does not exist
I've tried moving methods around, using includes, everything but I still can't get it to work. Any help would be really appreciated! Thank you.
try changing
.order('event_instances.start_date')
to
.order(:event_instances.start_date)
or if you need descending order add the .reverse_order method to the end of the query
This is the exact query which worked for my models Post and PostComments on both MySQL and PostgreSQL:
Post.joins(:post_comments).select('distinct post_comments.body, post_comments.created_at').order('post_comments.created_at desc')
So for you, it's equivalent should work too. If it still doesn't then please update your post with the fields of your model.
I have tried all of below snippets to use Python Parser in Field Calculator and update the values of a field called type based on a filed called MamerMN but in all of them I am getting Syntax error in Geoprocessing result window!
if !MamerMN! <= 0.151560:
return 1
and
if (!MamerMN! <= 0.151560):
return 1
and
if (MamerMN <= 0.151560):
return 1
and
def(MamerMN)
if MamerMN <= 0.151560:
return 1
and
def(MamerMN)
if (MamerMN <= 0.151560):
return 1
Can you please let me know what I am doing wrong?
You are writing your functions wrong. In the Field Calculator, make sure you check 'Show Codeblock' so the Pre-Logic Script Code box appears. Inside the Pre-Logic box, write your function-
def calcValue(mamerMN):
if mamerMN <= 0.151560:
return 1
and then in the box under, where it says the field_name =
you should write the name of the function and the field value you are passing to it surrounded by exclamations. So if your function above is named calcValue you would write
calcValue(!mamerMN!)
Without seeing a graphic of what your Field Calculator looks like, I suspect #csterling is probably right. However, an alternative is to just Select by Attribute where "mamerMN" <= 0.151560, then Field Calculate your selected features to 1 the regular way without necessitating a codeblock.
i'm facing issue in xpath-I need do a check two attribute values, if the condition satisfies need to do hard code my own value. Below is my xml.
I need to check the condition like inside subroot- if ItemType=Table1 and ItemCondition=Chair1 then i have to give a hard coded value 'Proceed'( this hard coded value i will map to target side of datamapper).
<Root>
<SubRoot>
<ItemType>Table1</ItemType>
<ItemCondition>Chair1</ItemCondition>
<ItemValue>
.......
</ItemValue>
</SubRoot>
<SubRoot>
<ItemType>Table2</ItemType>
<ItemCondition>chair2</ItemCondition>
<ItemValue>
.......
</ItemValue>
</SubRoot>
....Will have multiple subroot
</Root>
I have tried to define rules as below, but it is throwing error
Type: String
Context:/Root
Xpath: substring("Proceed", 1 div boolean(/SubRoot[ItemType="Table1" and ItemCondition="Chair1"]))
But it is throwing error like
net.sf.saxon.trans.XPathException: Arithmetic operator is not defined for arguments of types (xs:integer, xs:boolean)
Is there any other shortcut way to perform this.Could you please help me, i have given lot more effort. Not able to resolve it. Thanks in advance.
I am not sure where you are applying this but the XPath expression you are looking for is:
fn:contains(/Root/SubRoot[2]/ItemCondition, "chair") and fn:contains(/Root/SubRoot[2]/ItemType, "Table")
So here is an example returning "Proceed" or "Stop" as appropriate:
if (fn:contains(/Root/SubRoot[1]/ItemCondition, "Chair") and fn:contains(/Root/SubRoot[2]/ItemType, "Table")) then 'Proceed' else 'Stop'
To implement the above condition , i was initially tired to do in xpath, gave me lot of error. I have implemented by simple if else condition in script part of data mapper
if ( (input.ItemType == 'Table') and (input.ItemCondition == 'chair')) {
output.Item = 'Proceed'}
else {
output.Item = 'Stop '};
Make sure about your precedence. Example, Here in the xml structure( or converted POJO) ItemType has to be checked first then followed with ItemCondition.
&& not seems to be working for me, change to 'and' operator
If you were first time trying to implement the logic. It may help you.
