Hi @Rocko 
I tried looking in to this but still not sure how to create a service which will fulfill my requirement
I have a SQL service:

select * from Product_Table;

Can you give me a basic Idea that how can I include this pageNumer and pageSize to this service so that it can fetch the actual 
results in the mashup that will be appreciated

 

Thanks,

Lav.

In general you have two options. Getting the all of the data from the db into an infotable and show it only pagewise to the users. This is shown here: https://support.ptc.com/help/thingworx/platform/r9.5/en/#page/ThingWorx/Help/Mashup_Builder/Widgets/CreatingAPaginationService.html#wwID0EN3MDB

You would have no more DB queries when the user browses through the pages as TWX already got all the data. The disadvantage is that you pull all data ahead, even if it might never get rendered.

The alternative is to put the paging information into the query, using LIMIT and OFFSET keywords, e.g.

SELECT vehicle_number, dept_id, type FROM employee
ORDER BY employee.id DESC LIMIT 20 OFFSET 20;

which will get you entries 20 to 40. In that case you will have to add [[]] placeholders into the query (see https://www.ptc.com/en/support/article/CS413368) The advantage is that this way you only pull the data that is being displayed, the disadvantage is that when the table changes between the paging queries it might show updated data. Plus you will have to add some logic to determine how many rows there are in total, so the pagination widget knows how many pages to display.
