Microsoft SQL Server sa account password setup

首先要先安裝 Microsoft SQL Server Management Studio Express (以英文版為例) (可在 Microsoft 的網站下載)

1. 首先，點選 Object Explorer -> (Your Database) -> Security -> Logins -> sa，就會出現如下圖的視窗，將 Password 、 Confirm password 鍵入你想要的密碼。

2. 接著，點選小視窗左方的 Status，將 Login 的 Disabled 改成 Enabled (預設可能是 Disabled，因為 sa 是 SystemAdministrator 的帳號，權限很大)。

3. 重新開機(非必要，但是如果無法登入可以重開再試試看)

4. 重新開啟 Microsoft SQL Server Management Studio Express 後，在登入畫面將 Authentication 改為 SQL Server Authentication，接著在Login 、 Password 分別鍵入 sa、你所設定的帳號，就可以用 sa 帳號登入，也表示你可以寫程式透過這組帳號密碼來連接資料庫。

Setting MySQL to Use UTF-8 on MAMP (MySQL 5.5.9, or 5+)

I wanted to setup MySQL to use utf-8 on the MAMP installation on my Mac. I tried the instructions from this article: http://cameronyule.com/2008/07/configuring-mysql-to-use-utf-8/ However, I kept getting error messages that are similar to this one [ERROR] /Applications/MAMP/Library/bin/mysqld: unknown variable 'default-collation=utf8_general_ci' I did some search and realized that several variables are deprecated. Reference: http://dev.mysql.com/doc/refman/5.1/en/server-options.html Therefore, I added the following lines into /Applications/MAMP/conf/my.cnf [mysql] character-set-server=utf8 [client] character-set-server=utf8 [mysqld] character-set-server=utf8 collation-server=utf8_general_ci init-connect='SET NAMES utf8' I restarted the server and mysql run successfully with relevant variables being set correctly. In the "Variables" tab under phpMyAdmin interface (ex. http://localhost:8888/MAMP/?language=English) character set c...

ngrok, a service to help you get a public URL for your local webserver

If you are looking for options to test your web app hosted on your own machine (e.g., laptop) remotely with someone, I recommend using a service called ngrok. https://ngrok.com/ It has many usages, but in the context of testing an app hosted on your own machine, the most important part is giving you a public URL that will redirect all the requests to your local webserver (e.g., Apache, Nginx, or whatever server you are running). You can give this URL to a testing participant without the need to host the app on a remote server. For instance, if you are testing your app using a sever on your machine, typically you can access your app in a URL like: http://localhost:3000/?study=11 Using ngrok, you will have a dynamically generated URL like the following: https://3ebe3c019867.ngrok.io/ The service will redirect requests to https://3ebe3c019867.ngrok.io to http://localhost:3000 You can then share the following link with your testing participant for the participant to use your app. http...

How to update multiple fields in an SQL update statement

Syntax: /* the correct way of putting multiple fields together, using comma */ UPDATE `stories` SET `content`='Once upon a time ...', `update_time`=now() WHERE id=1; Note: there is no 'and' between the fields you are trying to update. You should use comma between each pair of the fields you are trying to update. Otherwise, you will likely get an '0' as the result value in the 'content' field without getting any error message. If you do the following, you will likely get an '0' in the 'content' field, without any error message /* the wrong way of putting multiple fields together, using 'and' */ UPDATE `stories` SET `content`='My Story' and `update_time`=now() WHERE id=1; See also: http://stackoverflow.com/a/7375371
