## How to Add Custom Column in Sales Order Table and Display in Admin Grid and Sales order view?

I want to add a custom attribute in sales order table I have added it using db_schema it is also showing in DB but how will I show it on admin grid and sales order view I also want to change it from admin panel and when creating order from admin it should also show there.Path to my module using is app/code/EAV/OrderAtt. Here is my db_schema file:

``````<schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xsi:noNamespaceSchemaLocation="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd">
<table name="sales_order" resource="sales" engine="innodb" comment="Sales Order">
<column xsi:type="datetime" name="delivery_date" nullable="true"  comment="Delivery Date"/>
</table>
</schema>
``````

Please tell which files do I need for this? I am using magento 2.35.

## Table returns different value depending on index

I have a problem, where I am trying to find the number of eigenvalues of a matrix smaller than 1. The matrix has a general form, given by

``````m(n_) := ReplacePart(IdentityMatrix(n/2), {i_, j_} -> Min(i, j) (-1)^(i + j));
``````

where $$n$$ is even. I’ve defined the function that counts the number of eigenvalues smaller than 1.

``````f(n_):= Length(Select(Eigenvalues(f), LessThan(1)));
``````

When I try to construct a table of the number of eigenvalues smaller than 1 for $$n =4,6,8,…$$ something very weird happens. Mathematica returns different tables depending on the index I use in the table. I.e., the two tables

``````Table(f(m(n))), {n, 4, 60, 2})
``````
``````Table(f(m(i))), {i, 4, 60, 2})
``````

are not the same. Has anyone encountered this and does anyone have an explanation?

## How to create an infinite Table of numbers

I wish to create to generate the set $${pm , 5^n : nin mathbb{N}cup {0} }$$ and solve the equation $$a+b =c+d$$ for all elements quadruplets $$a,b,c,d$$ in the set which satisfy it.

How would I go about this problem. I know how to use the Table and Solve commands in general but not in this particular case

## Why would a select on a single table refer to another table?

I have a simple select on a table, but the execution plan shows that another table is involved, in another database. This is definitely a table and not a view and I can’t see database auditing turned on so what could cause this?

## How can I design Person table in MySQL?

I have two person type: Users and Clients.
Users can login the panel but clients can’t login the panel.
My current database: (but this design not good for me. I need to connect these tables to the Persons table.)

My database:

You can see these tables storing same data like: firstName, lastName… but the difference is that the customer does not have a password.

How can I connect these tables to Persons table.

• Users can login with email and password.
• Client can’t login but have email for contact.

## postgresql – Postgres Specific table access

We have a requirement in our Postgres Database, We want to give specific table permissions to a particular set of user, we also have airflow in our environment which syncs tables, but sometimes any new columns are added to a table so we have to drop the table, due to which the specific table access for the user is gone. Access to a specific table is given through GRANT. Can you guys suggest us a way in which specific table access can be given, and will remain if the table is dropped and recreated?

## Problem in the table for the case where there is no number

For different values of time & force in At formula, I have a problem with the first case, which requires the first At, and I can not fix it. Also, in the table, how can I automatically enter values? I want to say that I want a table from 1 to n with At,time,forc

``````m = 1266.5 ;
k = 50   ;
Pt = ( {
{0, 0},
{.2, 1000},
{.4, 0},
{.6, -1000},
{.8, 0}
} );
ListLinePlot(Pt);
(Omega) =  N(Sqrt((k*1000)/m), 5);
Round(T = (2*N(Pi, 5))/(Omega), 0.1);
(CapitalDelta)t = Round(T/10, 0.1)
time = NestList(# + (CapitalDelta)t &, Part(Pt, 1, 1),
Round(FixedPoint((#) &, (Part(Pt, 5, 1)/(CapitalDelta)t))))
forc = Table(p1 = Interpolation(Pt, InterpolationOrder -> 1);
P1 = p1(time((i))), {i, 1, Length@time - 1})
At = Table(
At((i - 1)) +
1/(Omega)*(time((i)) - (forc((i)) - forc((i - 1)))/(
time((i)) - time((i - 1)))*
time((i - 1)))*(Sin((Omega)*time((i))) -
Sin((Omega)*time((i - 1)))) +
1/(Omega)^2*(forc((i)) - forc((i - 1)))/(
time((i)) -
time((i - 1)))*(Cos((Omega)*time((i))) -
Cos((Omega)*
time((i - 1))) + (Omega)*(time((i))*Sin((Omega)*time((i))) -
time((i - 1))*Sin((Omega)*time((i - 1)))))
, {i, 1, Length@time - 1})
data = {{{Subscript(t, i), s}, {Subscript(p, i), N}}, {Part(time, 1),
Part(forc, 1)}, {Part(time, 2), Part(forc, 2)}, {Part(time, 3),
Part(forc, 3)}, {Part(time, 4), Part(forc, 4)}, {Part(time, 5),

Part(forc, 7)}, {Part(time, 8), Part(forc, 8)}};

## What tools can be used to stream a data table out of sql server to a csv without reading it fully into memory?

I have a clunky script using BCP to pull a table without memory usage. I know I can use powershell commands to pull tables and write csvs but those commands read the entire table into memory, and I have some huge tables. Are there any other command line tools that will let me stream a table out of sql server (on the local windows machine) and into a csv?
