JdbcCursorItemReader uses a JDBC cursor (java.sql.ResultSet) to stream results from the database and is not thread-safe.

JdbcPagingItemReader reads items in pages of a configurable size and is thread-safe.

It may be useful to summarize the main points in one place, for future visitors to this question:

Server-Side Requests

When using serverSide: true, DataTables sends an Ajax request to your server.

This request is generated automatically by DataTables whenever a table re-draw takes place (and when the table is first initialized). The main actions causing a re-draw are:

• the user performs a column sort
• the user performs a search/filter
• the user navigates to a different table page

There can be other triggers/events which also cause a redraw - but user-initiated sorting, filtering, and paging are the main ones.

The structure of that auto-generated Ajax request is described in the "Sent Parameters" section of this page.

This is how DataTables tells your server what sorting, filtering, or paging action just took place.

Your table will typically have a simple ajax section so DataTables knows where to send this request - for example:

As I understand you are looking for a paging/scrolling using buttons (in addition to the normal scrollbar scrolling) to scroll through grid lines.

The FIXGRID has some server-side API which allows access/update to the scrolling:

It looks like your code binds relative the path "Master2Detail" on the detail side. BUT initially there should not be any existing binding in any parent view.

Your app should look more or less like this for binding path. UI5 is moving up the element to find data:

App-> Flexible ColumnLayout/SPlitView -> Master

App-> Flexible ColumnLayout/SPlitView -> Details

So adjust your bindings a described here OData error when bind to an element in a Master-Detail app

Second, you get this error because initially there is no relative binding in between your master bound element and the detail. Therefore, UI5 can only think this must be part of the master.

If you make up a relative binding in-between, you must inject the fragment by yourself. E.g. load the fragment, bind the loaded control(in aour case the VBox) and then use addItem etc. do attache it to the view.

Then I tried to switch to PAE paging by: unset PG -> set PAE -> write to %cr3 -> set PG and I succeeded. But I want switch to PAE paging directly. How is that possible?

It's not possible.

If "plain paging" is already in use/enabled, then you can't atomically enable PAE and load CR3 at the same time, so (regardless of whether you load CR3 first then CR4, or load CR4 first then try to load CR3) whichever instruction happens first will make the CPU crash before the second instruction is fetched.

The only way is to temporarily disable paging.

After all, the answer was quite easy as it has been part of the "product.component.html" page before the table view has been replaced by a list view.

The HTML tr tag featured the following jhiSort directive

This seems more like an eslint warning regarding react-hooks/exhaustive-deps.

If you are absolutely sure you want some logic to run only when the component mounts, then specifying an empty dependency array ([]) is the equivalent of a class-based component's componentDidMount lifecycle method.

React useEffect

If you want to run an effect and clean it up only once (on mount and unmount), you can pass an empty array ([]) as a second argument. This tells React that your effect doesn’t depend on any values from props or state, so it never needs to re-run. This isn’t handled as a special case — it follows directly from how the dependencies array always works.

You can ignore the warning, or disable the linting rule specifically for that line.

Example:

it looks like you are using wrong dependency. change to below line :

For targets you can use a column index number (indexing is zero-based):
