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.

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

Xingu M-ATX full-view sea view room chassis fearless W1 is now available: sliding glass fixed design, 159 yuan

Course Introduction：According to news from this website on July 24, Xingu launched an M-ATX column-free full-view sea view room chassis Fearless W1 on the e-commerce platform today. It is worth noting that Xingu officially recommends that the Fearless W1 chassis be used with a narrow M-ATX (244mm × 185mm) motherboard, because the standard M-ATX motherboard of 244mm × 244mm will block the fan on the right side of the motherboard. The glass panel on the left side of the chassis adopts a sliding glass fixation design, which is easier to install than the traditional four-corner screw locking method and also reduces the risk of glass breakage. The Xingu Wuwei W1 chassis adopts a side-mounted power supply design to achieve modularized heat dissipation. The top and right sides each include a heat dissipation mesh area on the front and rear to increase the ventilation area. This site summarizes the compatible specifications of Xingu Wuwei W1 chassis as follows:
