I have a database with the following relationship: relationship
These tables link a customer to an address: Cliente = client Clientenendereco = Many to many table between Endereco (table) and Cliente (table) Endereco = address Endereco_rua = address_street Endereco_cidade = address_city Endereco_estado = address_state
The cardinality is: Cliente NxN Endereco Endereco 1x1 Endereco_rua Endereco_rua 1x1 Endereco_cidade Endereco_cidade 1x1 Endereco_state

...ANSWER
Answered 2022-Mar-15 at 18:45If the string is transformed in the format of a JSON array, then it can be unnested via OPENJSON.
The values can then be masked and stitched back up with STRING_AGG (if your MS SQL Server version supports it)
Instead of using OPENJSON the function STRING_SPLIT can be used instead. But with OPENJSON you can order by the key.
QUESTION
I'm struggling with what seems should very much be a beginner task in CSS: scrolling and heights (when elements are nested more than 1 level deep).
I'd like to design layouts where default elements do not expand past their parent elements, and if they do, overflow: auto
kicks in and they start scrolling.
I don't want to set height; 100%
on every element though, as I need elements to only take up the space required, and so have been trying to use instead max-height: 100%
or max-height: inherit
on every element.
When using height: 100%
, the height of the parent is correctly picked up even when elements are nested several layers deep, as seen here: Code Pen 1
ANSWER
Answered 2022-Mar-07 at 22:41I need elements to only take up the space required
Setting widths relative to the parent will not make elements take up only the space required. By default height
is set to auto
which only makes elements as tall as they need to be.
Stop levelTwo from overflowing levelOne & universally tell all elements to never expand beyond their parent
Decide what your children will do when they are too large to fit within their explicit height parent:
- Visibly overflow (Default)
- Hide (Bad practice)
- Scroll
- Why does
max-height: 100%
not top out at the grandparent's height, whileheight: 100%
does? I would have expected similar behavior.
Why setting
height: 100%
on each works, butmax-height: 100%
does not
MDN - The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the percentage value is treated as none.
So because your levelOne container has a max-height and not a height, the max height is seen as 100% of auto - and 100% of "as much as you need" is a max-height of none.
- Is there a better method to not allow elements to spill out of their parent sizes?
Please let me know if this example is in the direction you want.
QUESTION
I have a react project I created using create-react-app
And I was trying to use sass in react by installing node-sass
for react.js
But I keep getting an error saying It's incompatible.
...ANSWER
Answered 2021-Dec-26 at 17:30The following errors occur only when there is a version mismatch. with node-sass
and installed node.js
- For this error, you can remove your node-sass and install node-sass version 6 using
npm install node-sass@6.0
- When you installed node sass 6.0 on node.js of version 14, you get the following error. you can fix it by installing
npm install node-sass@4.14.1
Or to avoid the error for all versions
You can use sass
instead of node-sass
or install the right node sass version

QUESTION
I have a block-diagonal sparse matrix in python with hundreds of thousands to millions of rows, but with many different sized blocks between 1x1 and 6x6; for example plt.spy() on a submatrix:
I need the inverse of this matrix without looping in python (too slow). I should be able to extract the block diagonal to get a list of 2d arrays (have not actually implemented this yet), but even then I cannot figure out how to apply, e.g., np.linalg.inv() to a bunch of different size matrices. Any ideas on inverting in sparse matrix form or via a list of diagonal blocks??
...ANSWER
Answered 2022-Feb-21 at 23:09AFAIK, there is no way to do that efficiently using Numpy. The best solution would be to group the blocks by size to compute them in a vectorized way (most Numpy function cannot work on array of different sizes). But this solution is not great because Numpy is not designed to compute small arrays and the overhead will be pretty big for such a small blocks.
A solution is to use Numba so to generate a fast native code to compute your blocks efficiently. Numba supports typed lists and np.linalg.inv
. If your input is a sparse matrix the best solution would be to extract the sub-blocks directly from it. However, Numba does not supports the Scipy's sparse matrices yet. That being said, you can for example extract the data
and indices
fields (which are Numpy array) of a CSR matrix so to compute them using Numba although this is a bit more complex to do.
QUESTION
When using function argument validation that depends on multiple
arguments in a (Repeating)
arguments block, the current argument is passed
to the validation function normally while other arguments are passed as
partially-populated
cell arrays. This contasts with how things work in non-(Repeating)
arguments blocks. Is this the expected behavior or a bug?
Consider the function dummy1
below, which uses the custom argument validation
function
mustBeEqualSize
to ensure that the arguments x
and y
have the same size.
Since the validation of y
depends on the value of x
, I'm calling this
"cross-argument" validation*.

element of the cell array:
QUESTION
I've been working on a side project to recreate diablo / tarkov like inventory screens with pure html, css, and js. I'm attempting to use the draggable api's built into html for this but am hitting a blocker. Everything working fine for 1x1 wide/high cell's / items. The problem begins when trying to add an item that is longer in width and/or height. I can still drag around the item but I can't get it to do two things.
- Cover all the cells correctly so there is no bleed through from the cells background.
- Stop the item from being placed in a cell that would cover another item.
My ideal solution modifies either the linked codepen below or provides direction / a solution on a more appropriate approach whatever that may be. The only constraint is that it must use html, css, and javascript. The only exception is jQuery.
