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

Steps to create peeling character effects using AE

Course Introduction：Create a text layer and texture layer during composition, apply inner shadow and bevel relief (to form a depression) to the text layer layer style. Duplicate one layer each of the text layer and texture layer, and pre-composite one of the text layer and texture layer as a particle composition. During particle synthesis, change the texture layer track mask to an alpha mask, create an adjustment layer, and apply fragmentation effects. During fragmentation effects, change the relevant parameters to form a fragmentation effect (the parameters may not match the image). Return to the main synthesis and change the text blending mode. Then the initial model of the peeling character is completed.
