migration

问题 I'm generating migrations between different yaml schema files: i.e. running: symfony doctrine:generate-migrations-diff And the resulting migration file has a whole slew of changeColumn calls that weren't added in the last schema file change. For example, if you run generate-migrations-diff without changing your schema file whatsoever, you should get an empty up() function. However, the function that results for me has a changeColumn call for virtually every table in my database. Am i doing

问题 Using Entity Framework Migrations (Beta1), using Update-Database command is all good during development. But when the application is running on some customer's server somewhere, I really want my application to automatically update it's database schema to the latest version when it's started. Is this possible? Documentation is scarce. 回答1: They aren't providing a way to do this until RTM, at which point they have promised a command line app and a msdeploy provider.

问题 I was wondering if anyone had any suggestions on how to normalize a database. Now, I don't mean designing the structure, I mean how to actually move the database data from an old structure to the new, normalized structure. I know I could write something like a PHP script, but I was wondering if there was a way to do it in SQL. Specifically MySQL. **EDIT: Has anyone tried something like SwisSQL? It's a migration tool, but i'm not sure if it will do what I'm asking. 回答1: Here is an Example of

问题 I just installed php 5.3.0 and it won't run php scripts utilizing short open tags like <?, only <?PHP. 回答1: You need to update your php.ini file. Set short_open_tag = 1 See the PHP Manual 回答2: That's because it's simply a bad practice. I suggest re-converting all your scripts to use <?php . If you're lazy, you can use a find and replace, if you have access to powerful command lines like bash you can use sed to do this for you. 回答3: http://us2.php.net/manual/en/ini.core.php you need to ini_set
