问题 input [31:0] write_data; input [4:0] write_reg; reg [31:0] registers [31:0]; always @(*) assign registers[write_reg] = write_data; I have a 32-bit input write_data , which i want to an assign corresponding index which i get from write reg.Error says you cant do continuous assignment which i think causes by always@(*) but if i remove that It says object "registers" on left-hand side of assignment must have a net type and its another error. 回答1: assign inside an always block is the procedural

问题 With MSSQL, I can mix in case, if...then, and while constructs in my SQL code. Is anything similar available for SQLite? I have not seen anything on "mixing procedurally" with SQLite, anywhere. Thanks. 回答1: SQLite doesn't have any loop syntax - FOR or WHILE . CASE statements are supported rather than IF. 来源： https://stackoverflow.com/questions/1885702/sqlite-flow-constructs-in-sql

问题 Following this process https://www.youtube.com/watch?v=UIbkfVWYRWQ I made a custom skybox procedural material for my app and applied it in the lighting panel. It works fine but when I make a build for Android, during the building process, the custom skybox is replaced with the "Default-Skybox" Once the build is done, the custom skybox comes back I found that https://answers.unity.com/questions/1211015/procedural-skybox-no-longer-working-on-android-bui.html But I can't find how to "Delete the

问题 Is there any way of testing procedural code? I have been looking at PHPUnit which seems like a great way of creating automated tests. However, it seems to be geared towards object oriented code, are there any alternatives for procedural code? Or should I convert the website to object oriented before attempting to test the website? This may take a while which is a bit of a problem as I don't have a lot of time to waste. Thanks, Daniel. 回答1: You can test procedural code with PHPUnit. Unit tests

问题 I know this one has been covered before, and perhaps isn't the most pythonic way of constructing a class, but I have a lot of different maya node classes with a lot @properties for retrieving/setting node data, and I want to see if procedurally building the attributes cuts down on overhead/mantinence. I need to re-implement __setattr__ so that the standard behavior is maintained, but for certain special attributes, the value is get/set to an outside object. I have seen examples of re

问题 I'm attempting to generate infinite random terrain. The terrain should generate the same every time given the same seed. I've tried using Java's Random function, creating the seed using various functions of the x and y co-ordinates of the given node on the terrain grid. Such as x*y+x+y+seed, 20*x+30*y etc. The problem with this approach is that I always see clear patterns in the numbers generated. So basically what I want is: f(x,y) = Random Number It would be helpful if the above function

问题 I'm having this argument about using Cursors in TSQL recently... First of all, I'm not a cheerleader in the debate. But every time someone says cursor , there's always some knucklehead (or 50) who pounce with the obligatory 'cursors are evil' mantra. I know SQL-Server was optimized for set-based operations, and maybe cursors truly ARE evil incarnate, but if I wanted to put some objective thought behind that... Here's where my mind is going: 1) Is the only difference between cursors and set

问题 I was once given this task to do in an RDBMS: Given tables customer, order, orderlines and product. Everything done with the usual fields and relationships, with a comment memo field on the orderline table. For one customer retrieve a list of all products that customer has ever ordered with product name, year of first purchase, dates of three last purchases, comment of the latest order, sum of total income for that product-customer combination last 12 months. After a couple of days I gave up

问题 Can we use Procedural Programming to solve any problem that can be solved using Object Oriented Programming Concepts? My problem is are there some particular problems which can only be solved using OOP concepts. Please help me understand this. 回答1: Yes. Anything that can be solved using OOP can be solved using procedural programming. In the end the compiler just turns your OOP code into assembly, which is procedural. It all comes down to what the combination of the CPU/RAM etc in your

问题 I am trying to sanitize my SQL calls and I am stuck where I am using a LIKE statement. I have tried most answers on SO, but most of them are in PDO or it's very confusing. This is the original code I have which works. if(isset($_POST['search'])) { $valueToSearch = $_POST['valueToSearch']; $query = "SELECT * FROM `galleries_info` WHERE CONCAT(`Gallery_Id`,`Gallery_Name`,`Gallery_Type_Id` ) LIKE '%".$valueToSearch."%'"; $search_result = filterTable($query); } else { $search_result = "Search
