[go-nuts] Show rows affected from query

I've written a program that allows users to put in MySQL queries and get results from it. Those queries can be selects, inserts, update, delete etc. I would a better sample of the code but currently the code is over 1000+ lines, but I do something like this: db,err :=sql.Open(mysql, loginCreds)

[go-nuts] Re: Go WASM question

A map in Go is not ordered, so even the iteration is not the same between several iterations. You can see: https://blog.golang.org/go-maps-in-action I suppose something similar occurs with objects in JS. So, maybe you can iterate the map and output a slice and then sort the slice, that is maybe

[go-nuts] encoding/json character escaping question

Hello The encoding/json package escapes 0xA (line feed), 0xD (carriage return) and 0x9 (horizontal tab) using the escape character '\'. However, when it comes to 0x8 (backspace) and 0xc (form feed), it uses the Unicode escape sequence staring with '\u'. Reproducer: https://play.golang.org/

That looks very nice, congrats! I like that it's simple and doesn't try to solve every problem, just simple relationships, so you can solve most of your simple DB schema needs (and most DB usage is quite simple in most services). Do you have any plans to add a Postgres driver? -- Marcin On Thu,

Burak, feel free to correct me if I am wrong, but now I think I understood the heart of the matter: Your approach to software development is different from mine. Nothing wrong with that. . you normally write sequential code, and uses concurrent code where it fits best. That is fine. . I use to

Re: [go-nuts] Channels may not be the best solution in Go

A point to consider though, is that often sequential code is used and concurrency is achieved by running multiple processes. This is pretty much the design of the cloud. A top-level coordinator partitions the work-load, and sequential programs process it, and the top-level assembles the results - t
