Hi Dave/Team,

    I have added an option under preferences menu to table data sorting by primary key.

Are you okay with text/labels?

"Sort table/view data by primary key(s)?"

Question mark (?) is missing your statement, which is must for a boolean flag.

"Sort View Data results by primary key columns?"

"If set to True, data returned when using the View Data option will be sorted by the Primary Key columns by default."

Ok. Will add this label and description. 

Why does it only apply if "All Rows" is used? I don't see any reason not to do it at all times.

As per discussion with Khushboo and Akshay will implement for "All Rows" as primary key columns ordering is already present for other options.

OK. Let's make it consistent then, and have the preference affect all options.

 

In case of the Last 100 rows, how will we get the result without sorting? 

SELECT * FROM table ORDER BY xmin DESC limit 100 :-)

That's a good point though. Let's just modify the description:

"If set to True, data returned when using the View/Edit Data - All Rows option will be sorted by the Primary Key columns by default. When using the First/Last 100 Rows options, data is always sorted."

 

Thanks!

Thanks!

Hello Hackers,

         It's related to applying data sorting on table data by primary key.

With the existing implementation, we can view the table's data using 4 options with the different orders by default

1 - All Rows (No order)

2 - First 100 rows (ASC order)

3 - Last 100 rows (DESC order)

4 - Filtered rows (No order)

In the https://redmine.postgresql.org/issues/5157  it's not clearly mentioned on which option to apply sorting by PK?  I'm assuming that should be on ALL Rows option.

Please suggest.

   Yes, for all those options. Sorting by Primary Key is all depends on the value set by the user in the Preferences dialog.

Thanks!

Hi Navnath,

Review comments:

1. If we have multiple Primary keys, then we should include all the keys into the Order by clause.

2. In the Preferences dialog, please put this option  in the Query Tool > Options instead of Result Grid and also change the Label.

3. Please optimize the code, as I can see objectname.sql file is being used in else condition also, which is not required. Based on the parameter setting, Just one call of that sql is enough.

Thanks,

Khushboo

Hello Hackers,

 Please find the modified patch with an option in Preferences for data sorting by the primary key. Also, the previous  patch was not working with table has no primary key.

Thanks!

Hi Dave/Team,

          This patch is related to the default sort order for the view table data. In pgAdminIII default ordering is by primary key and this is not working in pgAdminIV.

I have attached the patch with the back end code.

Please review it.

Question: There is one suggestion on https://redmine.postgresql.org/issues/5157 about to put a checkbox in the configuration for this behavior.

                  Do I need to implement that really? I yes, Is preferences a good place for that? / Suggestions?

I think we should make this optional, and yes, Preferences is a good place. The reason is that sorting data is not without cost - at the very least it will require use of an index to access what may be the whole table.
