How would you do to implement Audit Trail eg. add User Action(edit, new, delete, print), OldValue and NewValue in a separate "Audit Trail" table? Something like this:
ID | DATE | USERNAME | FORMNAME | ACTION | FIELDNAME | OLDVALUE | NEWVALUE
01 180513 user form1 edit Risk Low High
Old values must not be overwritten and I am kind of a stuck there because "patch" overwrites old values...
One option may be to confirm each change.
Example:
If user changes an auditable field, show confirmation popup.
Use the OnSelect Property of the "Confirm" button to write a new line to the Collection/Data Source
Use the Defaults line in your Patch command to APPEND this line to the Collection/Data Source each time rather than overwriting it.
Good luck!

I was wondering if there's a parameter for the currently authenticated psql user?
But then I wonder a more broader question - how can I just see what all the paremeters are?
I might discover some interesting parameters if I could see a whole list of them?
I'm only seeing online how to get the value of one parameter. Not a list...
Alvaro has answered the question how to list your current parameter values.
To get the authenticated user, you can call the SQL function session_user:
SELECT session_user;
The currently effective user can be seen with
SELECT current_user;
In psql, you can see details about your current database session with
\conninfo
Nonsense. Try these two SQL statements:
set foo.bar =42;
and then:
select current_setting('foo.bar');
You’ve just set, and read an entity that the PostgreSQL doc doesn’t seem to name. You might call x.y a “user-defined session parameter”. Where is its value held? Server-side, of course.
I too would like to know how to list the names of all currently defined such entities—system-defined, like TimeZone, and user-defined.

PostgreSQL does not have such a thing as server-side session variables, so it's not clear what you are asking about.
Some PLs (such as PL/Python, PL/Perl) have session variables (%_SHARED in PL/Perl, GD and SD in PL/Python for example), but they are internal to the PL, not part of the server proper.
psql also has variables, which you can set with \set, and you can get a list with the same command. I suppose that's not what you want though.
Maybe you refer to so-called custom GUC configuration parameters, which are sometimes abused as session variables. You can get a list of those using SHOW ALL or SELECT * FROM pg_catalog.pg_settings.
SHOW ALL below can show all parameters according to the documentation:
SHOW ALL;
This is how SHOW ALL works below:
postgres=# SHOW ALL;
name | setting | description
----------------------------+-------------+------------------------------------------------------------------------------------------
allow_in_place_tablespaces | off | Allows tablespaces directly inside pg_tblspc, for testing.
allow_system_table_mods | off | Allows modifications of the structure of system tables.
application_name | psql | Sets the application name to be reported in statistics and logs.
archive_cleanup_command | | Sets the shell command that will be executed at every restart point.
archive_command | (disabled) | Sets the shell command that will be called to archive a WAL file.
archive_mode | off | Allows archiving of WAL files using archive_command.
archive_timeout | 0 | Forces a switch to the next WAL file if a new file has not been started within N seconds.
array_nulls | on | Enable input of NULL elements in arrays.
authentication_timeout | 1min | Sets the maximum allowed time to complete client authentication.
autovacuum | on | Starts the autovacuum subprocess.
...
And, you can show one specific parameter with SHOW as shown below:
postgres=# SHOW allow_in_place_tablespaces;
allow_in_place_tablespaces
----------------------------
off
(1 row)
But, you cannot show more than one parameters with SHOW as shown below:
postgres=# SHOW allow_in_place_tablespaces, allow_system_table_mods;
ERROR: syntax error at or near ","
LINE 1: show allow_in_place_tablespaces, allow_system_table_mods;
So to show more than one parameters, use SELECT FROM pg_settings below:
postgres=# SELECT name, setting, short_desc FROM pg_settings WHERE name IN ('allow_in_place_tablespaces', 'allow_system_table_mods');
name | setting | short_desc
----------------------------+---------+------------------------------------------------------------
allow_in_place_tablespaces | off | Allows tablespaces directly inside pg_tblspc, for testing.
allow_system_table_mods | off | Allows modifications of the structure of system tables.
(2 rows)
In addition, current_setting() can show one specific parameter as shown below:
postgres=# SELECT current_setting('allow_in_place_tablespaces');
current_setting
-----------------
off
(1 row)
But, you cannot show more than one parameters with current_setting() as shown below:
postgres=# SELECT current_setting('allow_in_place_tablespaces', 'allow_system_table_mods');
ERROR: invalid input syntax for type boolean: "allow_system_table_mods"
LINE 1: ...ECT current_setting('allow_in_place_tablespaces', 'allow_sys...
I have created a Powerapp which is used to audit schools and the data saves to my SQL database. I have designed a report in SSRS to display the findings of the audit. The SQL table, shown below, stores the items in each room that were audited (i.e. desks, pcs, shelves etc) plus the name of the room and whether any actions need to take place. I need my report to display one table per room with the items down the left hand side and the name of the room as a title. This should be repeated for each room. There may be a different number of rooms in each report so this will be varied. I've included a screenshot of what the table needs to look like. When I create the table, I can only get the room names down the left hand side in one table and the items across the top. Please help.
Too long for a comment so I'll have to reply here.
Your data is not a a format that is particularly suited to this. I can't see how you can determine 'Compliant' from the data you have shown in your screen shots although it maybe that you have not shown everything you have available.
However, I would start by looking into the t-sql UNPIVOT function to get your data into a more normalised format. Using UNPIVOT you could turn your data into something like..
AuditID | Room | Item | Present
------------------------------------------
3019 | Reception | PC | True
3019 | Reception | Desks | True
3019 | Class 1 | PC | False
3019 | Class 1 | Desks | True
You can obviously extend this to include all pertinent data.
Once you have your data in this format, create tablix with 'item' and 'present' columns only. You will have a 'detail' rowgroup at this point. Right-click the rowgroup and add a parent group, set this group to be grouped by Room.
This will give you the basic layout, from there you can add some padding or blank rows to the room group or even page breaks.
If you cannot get past the UNPIVOT function then I suggest you post a new question specifically on that topic then return here once you have the data in the correct format
I am building an xlsx form for ODK. I have a dropdown list and a text-input field. I would like when I select a value from the ListA, a specific code to be filled in the text-input field.
For example if I choose "valueA" from the dropdown list the value "codeA" to appear in the text-input.
Currently I have an excel sheet with all the matches between the values in ListA and the corresponding codes (around 300). All the values in ListA are unique.
I was making some tests trying to use the "Calculation" field of Xls but no success till now.
Has anyone done something like that with Xls? Is it possible?
You could include a calculate field between the dropdown list and the text-input where you pull values from a csv file with the correspondence between valueA and codeA using the value selected in ValueA as a key. You can find an explanation of how the pulldata(...) calculation works here.
Here goes a brief example. In the survey tab:
|type |name |label |calculation|
|select_one keys|value_a|Value A | |
|calculate |code_a | |pulldata('data', 'value_column', 'key_column', ${value_a}|
|note |note |Code A value: ${code_a}| |
In the choices tab:
|list_name|name |label |
|keys |valueA_1|valueA_1|
|keys |valueA_2|valueA_2|
(.......)
And the file data.csv should look like this:
|value_column|key_column|
|valueA_1 |codeA_1 |
|valueA_2 |codeA_2 |
(.......)
Finally, I would advice to consider applying a cascade selection layout in value_a, because selecting one out of 300 values can be challenging. Another option could be sorting these choices alphabetically or in a different order, such that when someone fills-in your form she will know how to easily locate the appropriate choice.
Hope this helps!
I'm building a Excel-like table into web browser with React.js using only <div> not <table>.
Number of columns are about 90, rows are about 24000.
As we know, it is impossible to load whole data into HTML at single web page due to performance issue.
So I decided to show partial data to user using scrolling.
The main concept is simple, build HTML near user's viewport.
Guess if user is seeing 1800th to 1900th data in single viewport. I'will load only about 1750th ~ 1950th data into HTML. If user scroll up, I'll load HTML for 1700th ~ 1750th data and remove 1900th ~ 1950th data.
I think I need to manually manipulate scroll offset for getting pos where user is at. If each row's height is same as 40px and height of viewport is 1000px, then user will see 25 items at single viewport, so I need to load about 25(front) + 25(currently seeing) + 25(end) data and if user go upside or downside, I'll load additional data and remove data which far away from user.
However, I found that, requirement for my table is not matched with this situations. Here's my situation.
First, Each row's height is not same. Basically my table will show rows of row as single row. What I mean is, table single row can be looks like below,
| Photo| ProductName | Size Pool | Stock |
.... // Below are single row
+------+---------------+-------------------+------------+
| | Boots | 110-120 | 24 | // Row header (Shows Summary of child row)
+ +---------------+-------------------+------------+
| | Boots | 110 | 16 | // Row's row #1
+ +---------------+-------------------+------------+
| | Boots | 120 | 8 | // Row's row #2
+------+------------------------------------------------+
...
+------+---------------+-------------------+------------+
| |Leather Shoe | 120 | 8 | // Row can come with no header row, only single
+------+---------------+-------------------+------------+
...
Like above, if product has more than 2 options, then it merge into rows of single row and show with summary header. And if not a option product, it shows only it's row. And if content inside the row is big, it will stretch to fit the content inside
All data came from remote DataBase which retrieve data via REST API.
DataBase scheme is like below, 2 table as example.
Table #1 ProductInfo
+--------------+------------+------------+-----------+
| GroupNumber |ProductName | Size | Stock |
+--------------+------------+------------+-----------+
| 1 | Boots | 110 | 16 |
+--------------+------------+------------+-----------+
| 1 | Boots | 120 | 8 |
+--------------+------------+------------+-----------+
| 2 |Leather Shoe| 120 | 8 |
+--------------+------------+------------+-----------+
Table #2 GroupInfo
+-----------+------------+--------------+
|GroupNumber| SizePool | ImageURL |
+-----------+------------+--------------+
| 1 | 110-120 | https://abc |
+-----------+------------+--------------+
| 2 | 120 | https://def |
+-----------+------------+--------------+
And future requirements are below, (And most of them are implemented)
Sort by each columns, multi-pivot sort by row of row OR row (Handled via SQL)
Filter data by expression (Handled by client)
Hiding, resizing, change order of column(s) (Handled by client)
Interactable component inside cell like DatePicker, Pop-up etc... (Handled by client)
I succeed to create such table with page based method. But I need scrolling viewport table.
The table contains lots of dependent value column like sum, average which are not in stored in DB except for special reason (Like performance). (Most of them are handled by DB View or Procedure including sorting, calculations etc). So overall performance is really important.
I considered few questions and way to handle this, Can you check and give me a advice?
Q1. How can I decide when data should be loaded and removed and it's amount?
Data height is not consistent, so I think I cannot use scroll offset or data number as measurement criteria. (Is it possible with predictable way?)
Is it possible to archive by accessing DOM element? I'm new to Web dev. Sorry.
Q2. I can get a data from DB in 2 different ways.
Getting ProductInfo And GroupInfo seperately [<ProductInfo>,...] And [<GroupInfo>,...]
Getting Single group which object like this { group:<GroupINfo>, values:[<ProductInfo>,...] }
which is better for performance in this case in typical situations?
Q3. If I got a data like { group:<GroupINfo>, values:[<ProductInfo>,...] }, is there any problems with performance?
Like query overhead (I need to use query joined 6 times with maximum 6 depth nested SELECT query with 30 calculated columns for single data retrieval attempt. -- Pre-calculated view or table can have problems because I have many user to use it and update frequently. So I need to worry about Mutual Exclusive at least on updating.
I'm sure that above query's performance is sufficient for cropping if I got data like [<ProductInfo>,...] And [<GroupInfo>,...]. But I think later one is better. so I need to change interface if possible.
Q4. If I crop whole data from DB and structurize at the beginning, and load and remove data only for DOM, Can it be a good way?
Of course, Q1 is my primary matter, but this also seems good except for data sync with DB (Cause other user can update value while client contain outdated data)
I considered of using Infinite-Scrolling, but this is not for my case, I need perform load data and remove data at the same time. But infinite-scrolling seems dose not support removing data from viewport. Also inconsistent row height may be a problem.
I found react-virtualized and it works.
It also support dynamic resizing of row and it greatly helped
I have a table in my database that stores users, for example:
userID | userName | email | password | wins | losses | exp
Now I want the user to be able to get achievments in my game, like "win 5 games in a row", and I obviously want that progress in the database (Google app-engine) so progress is not lost when user exits client. Example of achievment table:
achievmentID | achievmentTitle | description | reward
Now how would I go about saving achievment progress for each user in the best manner? I need to save both progress (like 3/5 games in a row won) and if achievment is completed or not.
The product is for Android/iOS and uses google app engine (datastore) as database.
The way you set up your table would not be very efficient. In my mind to be the most efficient, you would have to make a new column on your users table (not new table, but after the 'exp') and create a sort of key for achievements. For example, you could give each achievement an ID (which you would keep track of like in a notes on notepad or something).
Then, when they get that achievement, you would put "123/" and if you did another achievement, it would say something like "123/461/".
Then you could make a script that breaks apart these IDs to see what achievements have been completed.
