I am trying to output hierarchical JSON from a SQL Server database for a company org chart.

I would like to display the data in something like https://github.com/dabeng/OrgChart.

I have been able to build a query that outputs the hierarchy into a flat table as follows:

I was able to achieve what I wanted by using FOR JSON PATH but this will only really give me the data I need to a single level of hierarchy.

Would anyone know how to have multiple levels of hierarchy outputted from T-SQL to give me something like the following output:

I'm new to Rust and I'm trying to come up with a simple backup program. In a first step, the files are broken down into blocks of variable length (via content-defined chunking).

To do this, I have to read the file byte by byte. Unfortunately, I find that the process is terribly slow. With dd I can read at up to 350 MiB / s. Nevertheless, I only get about 45 MiB / s with the following Rust code. (I left out all the chunking stuff there.)

The file I am reading is around 7.7 GiB in size.

I am trying to produce a table within my Rmd that includes references. This sits within a manuscript that will contain these and other references. Within the manuscript I'm able to use [@xxxx] ok. I tried this as a column in the table and using the gt, Datatable and Flextable packages with no success.

This is what my Rmd looks like

I am running this query on a table:

This subquery is part of a large query.

I have a table called Call_Data with about 850k records. I need to update a column but this query is taking a long time - about an hour.

Basically, select product_type from leads_file. If it is null then select product_type as HUA from Routing_Data, else select product_type from leads_file and update the product_type column in Call_data table with this value.

Thanks in advance!

I have two dataframes data1 and data2 which have information like below:

I wanted to try and create a tree from a list of paths and found this code on stackoverflow from another question and it seems to work fine but i would like to remove the empty children arrays instead of having them showing with zero items.

I tried counting r[name].result length and only pushing it if it greater than zero but i just end up with no children on any of the nodes.

I have a list of dictionaries written to a data.txt file. I was expecting to be able to read the list of dictionaries in a normal way when I load, but instead, I seem to load up a string.

For example - when I print(data[0]), I was expecting the first dictionary in the list, but instead, I got "[" instead.

Below attached is my codes and txt file:
