QUESTION
I want to combine multiple date columns by taking the least date value among date columns excluding the nulls values. I have tried various ways such as using 'case when' and 'Min' function but can't weed out NULL values. I am not looking for first non-NULL value either. What makes matters worst is that the 'LEAST' function is not available in Netezza.
My dummy data(not highlighted columns), my desired output(highlighted columns) is shown in the table below:
...ANSWER
Answered 2021-May-21 at 10:30The least()
function is available as a part of the SQL extension toolkit.
Here is the link to the least() function -> https://www.ibm.com/docs/en/netezza?topic=functions-least
Here is the install instructions -> https://www.ibm.com/docs/en/psfa/7.1.0?topic=setup-installing-netezza-sql-extensions-toolkit
SQL Toolkit can be downloaded from IBM Fix central.

QUESTION
I am trying to find all child elements of a div that contains a specific string. For example, in the following HTML content, I need to find all child elements of the "Trees" div, including the
Trees
pair. There are no classes or IDs associated with each div, so I can't search for IDs or classes.
I tried the following code, using an answer from https://stackoverflow.com/a/55989111/1466973 , but the expected content was not returned by the function.

Since you are using DOMDocument

QUESTION
I'm working on filtering a website's data and looking for keywords. The website uses a long JSON body and I only need to parse everything before a base64-encoded image. I cannot parse the JSON object regularly as the structure changes often and sometimes it's cut off.
Here is a snippet of code I'm parsing:
...ANSWER
Answered 2021-May-12 at 19:09Regular expression should work here. Try matching with the following regular expression. It matches the desired sections, when I try it in https://regexr.com/. Also, regexr helps you understand the regular expression, in case you are new to it.
QUESTION
I am trying create a context menu similar to Pinterest's context menu in their iOS app. Long pressing a post reveals a four button view, which while the user continues the longpress, is then able to drag and select the other buttons. Letting go of the long press will either select whichever button you are currently selecting or dismiss the menu altogether if you don't have anything selected. Please see an example of this below:
So far, I've tried something similar to Apple's documentation here: https://developer.apple.com/documentation/swiftui/longpressgesture
But it seems that the gesture finishes as soon as it hits the minimumDuration defined in the gesture. I'd like the gesture to continue for as long as the user is holding, and end as soon as they let go.
Additionally, I am in the weeds when it comes to the dragging and selecting the other buttons. Here is my approach so far:

if you press and hold, you get a similar effect.
QUESTION
I have created a number of nuget packages with msbuild targets that help me take care of common boilerplate in my .NET projects. Here I am working on a simple .props
file which is aimed to make the copyright information in the compiled assembly and the nuget package consistent.
Currently I am struggling with the fact that this props file does not get respected in all build phases of a target project.
The props file looks roughly like the following (full source code available in github):
...ANSWER
Answered 2021-May-03 at 13:01It looks like the issue is more complex, because it happens when cross-targeting projects are involved.
Thanks to a github issue I got more insight on how the GenerateNuspec
task is working with imported msbuild tasks, props and targets, so I came to a solution for my own problem. The details below:
The use-case where the problematic behavior is observed is because:
- My nuget packages containing props and targets only include them under
build
, but not under thebuildCrossTargeting
folders. - The linked above issue showed me, that when the project is cross-targeting, the
GenerateNuspec
flow will only include custom props/targets present in thebuildCrossTargeting
folder, thus my targets got ignored - When I produced a new nuget package where I used both
build
andbuildCrossTargeting
, the issue disappeared.
Conclusion -- be very careful when creating your own msbuild targets as nuget packages -- scenarios such as cross-targeting projects need special handling!
QUESTION
I have a 3 deep array. Currently, the code will isolate a record based on one field ($profcode) and show the heading. Eventually, I am going to build a table showing the information from all the other fields. The code so far is using in_array and a function that accepts $profcode. I am unsure if (and how) I need to use array_keys() to do the next part when I retrieve the "Skills" field. I tried:

QUESTION
I need your help for a minute.
We have the problem that players can assign more things in the inventory than normally possible (example: I don't have "25" sandwiches but if I enter "025" as value I can give 25 to another player).
Does anyone know how I can fix this?
Code-snippet is here:
(server-side):
...ANSWER
Answered 2021-Apr-15 at 21:57You have a couple of issues:
- The comparison
if item == 'bandage' or 'bread' ... then
is not going to do what you expect it to do, asbread
will be evaluated astrue
(as it's not compared withitem
value), so the entire expression will be evaluated astrue
regardless of what the actual value oritem
is. You need to rewrite it asit item == 'bandage' or item = 'bread' ... and so on
- I don't see any comparison with available items, so either it's happening somewhere else (and is not applied because of the first issue) or is not done.
