So I have a problem I can't seem to figure out. I have to make a fuction(in postgres, also called a stored procedure). The function has to check if a given id is a certain 'thing' for example:
Given id 10, is has the check if the id is a human(another table) or a animal(another table). If it is one of the two, it has to get all the attributes of that tabel. This repsonse has to be json formatted so that the application builder can build an extjs application around it.
So can someone give a push in the right direction, do I need to have a json out parameter? or a character varying? How do I give something back based on whenever the table exists or not. I hope someone can give me a push. Much appreciated!

Just gonna start with saying, I sure do know how to pick a challenge (based on my skillsets or the lack of).
I'm trying to figure out how to generate a true/false style table through PowerAutomate from a PowerBI output (Exciting, right?!).
The data is a report of Active Directory users and their group memberships. A Sample of the source data looks like this;
The desired output would look something like this;
How the data is being generated through PowerAutomate and PowerBI;
I'm trying to research JSON Schemas and how that all is supposed to work, but I am just really not sure where to start. Finding an example that matches well enough to replicate into my use case is turning out to be more difficult. Assuming this is a function JSON can complete.
I'm trying out these sites, its helping me learn but is probably not going to solve my issue;

Any help would be very much appreciated. Not always looking for the direct answer to the problem, if documentation exists that would push me in the right direction.
There is a new DAX function added recently called TOJSON that might solve your problems, and I believe the imagined use-cases for this function includes your current challenge.
Here is what I would do:
Prepare your table exactly as in your desired output, in Power BI
Lift the entire query used to generate the table using Performance Analyzer
In DAX Studio, paste the query you copied and isolate the final output table - wrap this in TOJSON and verify your results
Use this query in Power Automate - should give you the JSON response you are after directly
If you need to parse the JSON, you can copy the output from DAX Studio as basis for the schema in Power Automate
On our Wordpress site, we use a plugin called s2member and it stores the levels (roles) of our clients as well as the times they were assigned a specific level in our database. I would like to create a table that shows when a user was assigned a specific level. I'm having a challenge getting the data I need because of the way the data is stored in the field. It stores all of the levels along with the associated dates and times when a user's level was changed in one field. In addition, it stores all of the times as Unix timestamps. Here's an example of a typical field associated with a client:
a:20:{s:15:"1562695223.0001";s:6:"level0";s:15:"1562695223.0002";s:6:"level1";s:15:"1562695223.0003";s:6:"level2";s:15:"1562695223.0004";s:6:"level3";s:15:"1577906312.0001";s:11:"ccap_prepay";s:15:"1596575898.0001";s:12:"-ccap_prepay";s:15:"1596575898.0002";s:13:"ccap_graduate";s:15:"1596575898.0003";s:11:"ccap_prepay";s:15:"1596575898.0004";s:7:"-level3";s:15:"1597196952.0001";s:14:"-ccap_graduate";s:15:"1597196952.0002";s:12:"-ccap_prepay";s:15:"1597196952.0003";s:13:"ccap_graduate";s:15:"1597196952.0004";s:11:"ccap_prepay";s:15:"1598382433.0001";s:14:"-ccap_graduate";s:15:"1598382433.0002";s:12:"-ccap_prepay";s:15:"1598382433.0003";s:11:"ccap_prepay";s:15:"1598382433.0004";s:6:"level3";s:15:"1605290551.0001";s:12:"-ccap_prepay";s:15:"1605290551.0002";s:11:"ccap_prepay";s:15:"1605290551.0003";s:13:"ccap_graduate";}
There are four columns in this table: umeta_id; user_id; meta_key; meta_value. The data above is stored in the meta_value column.
You'll notice that it also has multiple ccap_* entries. CCAP stands for custom capapability and I would like to be able to chart those assignments and associated times as well.
Do you have any idea how I can accomplish this?
Thank you for any help you can give.
I talked to an engineer about this and he told me that I would need to learn Python and I believe he said I would need to learn how to also use Pandas and Numpy to extract the data I need but he wasn't exactly sure. I started taking a data analyst course on Coursera but I still haven't learned what I need to learn and it's already been several months. It would be great if someone could provide a solution that I could implement more quickly and use on an ongoing basis.
If there's a way to accomplish my goal by exporting this table to a CSV file and using Microsoft Excel or Google Sheets, I'm open to that too.
Here's an image of the table (if it helps):
Database table
Here's an example of my desired output:
Desired output
In my desired output, I used Excel and created a column that converts the Unix timestamp to a short date and another column where I used a nested IF statement to convert the CCAP or level to its meaning that we understand internally.
I am looking for a scripted/automated way (presumably VBA?) to take an Access query and generate some kind of savable, searchable, publish-able documentation on the data lineage. So if there were a bunch of layered/nested queries, or even passthrough queries, along the way I want a way to trace the final fields in the specified query back until I get back to the original source tables/fields.
Everything I've found seems to do database documentation focused on how the table relationships are configured. I'm looking for a way to get the documentation of the user-created portion, down to the field. I'm very open-minded on what format the output is in. I'm convinced this must be possible, but haven't had any luck yet.
I'm also open to recommendations for a third-party application if it could do this.
Thanks in advance!
Access does have a built in “dependency” feature. The result is a VERY nice tree-view of those dependencies, and you can even launch such objects using that treeview of your application to “navigate” the application so to speak.
The option is found under database tools and is appropriately called Object Dependencies.
The result looks like this:
While you don't want to use auto correct, this feature will force on track changes. If this is a large application, then on first run a significant delay will occur. After that, the results can be viewed instantly. As noted, not only do you have a hierarchical tree view, but objects in the tree view can be clicked on to launch the object in question.
And the above will work for a query that based on a query etc. all the way down to the base table.

This is a set of queries I wrote to provide the kind of documentation you're looking for. It seems a bit kludgy, but it works for me. It's not a simple as the other response, but it provides output that can be incorporated into other documentation.
Note - the documentation is out of date with respect to Union queries. The query I have to analyze Union queries seems to only pick up the 1st two things that go into the Union, so I changed this to a Make Table query, and manually edit the resulting table to add the missing relationships.
To use the queries:
Copy the table and all the queries into your database
Run the "Mapping Unions Make Table" query
Manually edit the Unions table if necessary
When you run any of the 3 main output queries, you are prompted for the Top object you want to analyze. Enter the name of a query or table to find all the dependencies for that object. The three main outputs are:
Mapping Summary - lists all of the objects that go into the top object and all of the objects that go into them, to a depth of about 10 (depth is controlled in the "Mapping all parents" query)
Mapping summary without duplicates
Mapping summary duplicates
I especially like the 2nd output - this is in a format that can be saved in Excel and input to Visio's Org Chart Wizard to get a simple graphical representation of the relationships. Then the 3rd output query can be used to manually add in the queries that go into more than one other query, which Visio's wizard cannot handle.
I'm starting to learn Talend and I'm facing this problem: I have several ID's as an input and I want to make a lookup for each of these ID's to output the obtain data in a Json output.
Here's an image showing what I want to achieve:

I have a tXMLMap with a lookup to the table where I want to find the villains from the villainID's list. The image shows how I can get the ID and Name for one of the villainID's and output it in it's respective json field but this method only works for one ID lookup at a time.
What's the best way to achieve this?
Thanks!
You should be able to copy your second input table 8 times and link all of those back into the tXMLMap component and link those by key as you already have done and join those up to where it needs to go in the XML mapping.
Alternatively you could use a tMap component in a previous step and use that to generate waveNvillainN's dispName by joining the id of your lookup table to all of the waveNvillainN's ids. This should then leave you with all of the necessary fields to populate the XML mapping.
This is the way I could find out to solve this issue, I think it's the same that #garpitmzn and #ydaetskcoR meant but I'm not sure. This works perfectly and was easy to implement but I'd just hope there was a way to have less clutter of components.

Is it possible with LINQ to do a cross tab query to add new columns? These columns come from a second and third table and need to be converted to JSON to be displayed in a Telerik table.
One table contains the name of the columns that need to be displayed and the other contains the value for the rows of each column, and this relates to the first table, which has the main related data.
I have investigated dynamically creating the extra columns, but also come unstuck as they need to go through JSON serialization, as well as the difficulties of creating new properties within any class dynamically.
Any ideas would be helpful.
Regards
Mark
I hope this helps, although I'm not sure I understand completely what you're asking ...
Since you're serializing to JSON anyway (and so presumably are not overly concerned with schema/type info), I would suggest just using a Dictionary and populating your data that way. It sounds like you could run some kind of nested loop, cycling through the column names from the one table, and pulling the values from each column from the second table.
EDIT
BTW, it is possible to do dynamic properties using System.ComponentModel, although this seems like overkill from how you described your scenario (you don't require data binding, for instance). Here's a good post on SO, if you're interested: Data binding dynamic data
