Ways to fix issue 2003 (HY000): Unable to connect to MySQL server 'db_mysql:3306' (111)

Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records. I want to first perform a query limited to 3 records, and then sort the results of this query by a column called ContactName. I think this might be a nested query. Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri

Shortest way to convert all PHP types to string

I'm writing a general system that I hope can one day be applied to fields like medicine (i.e. it's "scientific"). I think the best way is to represent all the data in php with strings (true will be "true", false will be "false" and so on). The reason for this is that in php any value has a unique string representation (such as the php code itself). I post this question to speed up the design process of this program. Some values are easily converted to strings: numbers, booleans, etc. Some are not easy: objects, arrays, resources. I think the transfer object and

What should I do if the NVIDIA control panel only has 3D settings?

Course Introduction：NVIDIA is the preferred graphics card hardware brand for many users. They usually set it through the NVIDIA control panel. However, some users find that their NVIDIA control panel only has 3D settings. What's going on? The editor below will share with you the solution to the problem that the NVIDIA control panel only has 3D settings. The reason why the NVIDIA control panel only has 3D settings: Most computers currently use dual graphics card settings, usually a combination of Intel core graphics and NVIDIA independent graphics cards. So when it comes to adjusting your screen display settings, just open the Intel Control Panel.

What should I do if there is only one 3D setting in the nvidia control panel and no others?

Course Introduction：When we use a desktop or laptop, if we want to set up the nvidia graphics card control panel, we find that except for the 3D settings, all the other options are gone. In this case, I think you can try to adjust it in Intel's graphics card settings.

Nowadays, notebooks with independent graphics have dual graphics cards, independent graphics + combined graphics. 2.
