QUESTION
My app consists in letting you add lists in which you can keep your notes. Therefore, I have this NotesListActivity where I can add and keep my Lists. I wanted to filter this lists following the https://www.youtube.com/watch?v=CTvzoVtKoJ8 tutorial and then I tried to adapt it to my code like below. Could you please tell me what is the problem here, cause I don't even get an error, I just not get any title of list as result. So, this is what I have in my RecyclerAdapter:
...ANSWER
Answered 2021-Jun-13 at 20:18The problem is that you are using an empty notesListAll list for filtering results; you need to populate it with the list of notes in the constructor
QUESTION
Sorry I don't show my variables or anything, tried to give information only pertaining to the questions. This 1 Sub is huge.
Currently my code allows a user to select multiple files, the files selected will be sorted in a specific format, then loaded into 2 different arrays. Currently loads Columns D:E into 1 array and Columns I:K into another array (from selected files QSResultFileWS, and returns those arrays to my destination FormattingWS. I'm still trying to learn arrays so if the methodology I used to do this isn't proper, be gentle.

Replace you lines load the arrays
QUESTION
I have a store setup that has multiple arrays
I'm trying to search all arrays at once, via a textfield.
I can get this done, by calling a selector function on keyup, that filters the 4 arrays and pushes to a new array.
I've thought about merging all the arrays to one array before filtering, but I want to keep the results separate, as they are going to be displayed in categories.
Just trying to see if I can streamline the performance at all and if there's a more concise way of doing this, in case I need to do something similar with larger arrays.
my textField function:
...ANSWER
Answered 2021-Jun-15 at 19:16This should implement the selector function with less code and make it more adaptable to kinds of data, if needed you can specify a more precise type in the filter function.

Some of my code, for populating some tables, has code like this
...ANSWER
Answered 2021-Jun-15 at 18:27This was difficult for me to understand, so I wanted to share if anyone else has the same issue.
It seems that an async method will break a method chain, there's no way around that. And since fetch is asynchronous, await must be used, and in order for await to be used, the calling method must be declared async. Thus the method chain will be broken.
The way the method chain is called must be changed.
In my OP, I linked https://jsfiddle.net/47sfj3Lv/3/ as a much simpler version of the same problem. StackOverflow's 'fiddle' effectively blocks 'fetch' for security reasons, so I need to use JSFiddle for demonstration.
Here's a working version of the same code using then and how/why it works, and a slightly shorter version, because await can be specified with the the fetch, obviously.
QUESTION
I have a AdvancedCollectionView from Windows Community Toolkit version 6.1.1 and trying to use it to filter out on 2 string properties.
I have created a simple app to reproduce the issue : https://github.com/touseefbsb/UWP-Filter-List
It has a textbox for filtering between StartNumber and EndNumber properties of items.
but as soon as I enter text "123" into it, it shows no item in the ListView when it should actually show only the first item, based on the test logic.

QUESTION
I want to generate a dynamic LINQ expression for filtering only with Date, but my column is a Datetime field in the DB. Due to this the operator "equal" and "not equal" is not working because it is appending some default time to my input and trying to match with the data. If there is any way to Generate a LINQ expression that will compare only date by excluding the time.
This is my code:
...ANSWER
Answered 2021-Jun-15 at 06:18Don't do it; go the route suggested of using a date range instead
Always seek to avoid creating queries that manipulate table data before a comparison is done. Suppose you have a table with ten million datetimes in, and they're all indexed
The database will probably use the index for this:
QUESTION
Hello all!
I recently learned that in newer versions of SQL Server, the query optimizer can "expand" a SQL view and utilize inline performance benefits. This could have some drastic effects going forward on what kinds of database objects I create and why and when I create them, depending upon when this enhanced performance is achieved and when it is not.
For instance, I would not bother creating a parameterized inline table-valued function with a start date parameter and an end date parameter for an extremely large transaction table (where performance matters greatly) when I can just make a view and slap a WHERE statement at the bottom of the calling query, something like
ANSWER
Answered 2021-Jun-14 at 22:08You will not find this information in the documentation, because it is not a single feature per se, it is simply the compiler/optimizer working its way through the query in various phases, using a number of different techniques to get the best execution plan. Sometimes it can safely push through predicates, sometimes it can't.
Note that "expanding the view" is the wrong term here. The view is always expanded into its definition (NOEXPAND excepted). What you are referring to is called predicate pushdown.
I've assumed here that indexed views and
NOEXPANDare not being used.
When you execute a query, the compiler starts by parsing and lexing the query into a basic execution plan. This is a very rough, unoptimized version which pretty much mirrors the query as written.
When there is a view in the query, the compiler will retrieve the view's pre-parsed execution tree and shoves it into the execution plan, again it is a very rough draft.
With derived tables, CTEs, correlated and non-correlated subqueries, as well as inline TVFs, the same thing happens, except that parsing is needed also.
After this point, you can assume that a view may as well have been written as a CTE, it makes no difference.
Can the optimizer push through the view?The compiler has a number of tricks up its sleeve, and predicate pushdown is one of them, as is simplifying views.
The ability of the compiler here is mainly dependent on whether it can deduce that a simplification is permitted, not that it is possible.
For example, this query

It polls the specified file for new lines every second and outputs them to the pipeline.
Therefore, you need to perform processing as part of the same pipeline, using a ForEach-Object call:

Install filtering
You can use filtering like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
