Laravel 10, can you create a new database in a migration?
问题
我正在构建一个需要在一个PGSQL数据库服务器上拥有两个数据库的环境，一个是生产数据库，名为laravel，另一个是测试/开发数据库，名为laravel_test。是否有办法在Laravel中使用数据库迁移来创建新的数据库？我一直在尝试类似以下的方法：
$dbName = config("database.connections.pgsql-test.database");// 创建第二个数据库DB::statement("CREATE DATABASE $dbName");
但最终出现了以下错误：
SQLSTATE[25001]: Active sql transaction: 7 ERROR: CREATE DATABASE cannot run inside a transaction block (Connection: pgsql, SQL: CREATE DATABASE laravel_test)
在处理数据库特定操作方面，我经验有限，是否有一种方法可以使用主要的（pgsql）DB连接来迁移新的数据库，以便我可以使用这个连接（pgsql-test）？
（config/database.php）
'pgsql' => ['driver' => 'pgsql','url' => env('DATABASE_URL'),'host' => env('DB_HOST', '127.0.0.1'),'port' => env('DB_PORT', '5432'),'database' => env('DB_DATABASE', 'forge'),'username' => env('DB_USERNAME', 'forge'),'password' => env('DB_PASSWORD', ''),'charset' => 'utf8','prefix' => '','prefix_indexes' => true,'search_path' => 'public','sslmode' => 'prefer',],
以便我可以使用这个连接（pgsql-test）：
'pgsql-test' => ['driver' => 'pgsql','url' => env('DATABASE_URL'),'host' => env('DB_HOST', '127.0.0.1'),'port' => env('DB_PORT', '5432'),'database' => env('DB_DATABASE', 'forge') . "_test",'username' => env('DB_USERNAME', 'forge'),'password' => env('DB_PASSWORD', ''),'charset' => 'utf8','prefix' => '','prefix_indexes' => true,'search_path' => 'public','sslmode' => 'prefer',],
而不需要手动创建数据库？
英文:
I'm building an enviroment that needs two databases on one PGSQL database server for Laravel, the production one is named laravel, and the testing/dev one would be named laravel_test, is there any way to create the new database using database migrations in Laravel? I've been trying things like
$dbName = config("database.connections.pgsql-test.database");// Create the second databaseDB::statement("CREATE DATABASE $dbName");
but end up getting an error that states this:
SQLSTATE[25001]: Active sql transaction: 7 ERROR: CREATE DATABASE cannot run inside a transaction block (Connection: pgsql, SQL: CREATE DATABASE laravel_test)
I'm inexperienced when it comes to database specific operations like this, is there a way I could migrate a new Database using this primary (pgsql) DB connection:
(config/database.php)
'pgsql' => ['driver' => 'pgsql','url' => env('DATABASE_URL'),'host' => env('DB_HOST', '127.0.0.1'),'port' => env('DB_PORT', '5432'),'database' => env('DB_DATABASE', 'forge'),'username' => env('DB_USERNAME', 'forge'),'password' => env('DB_PASSWORD', ''),'charset' => 'utf8','prefix' => '','prefix_indexes' => true,'search_path' => 'public','sslmode' => 'prefer',],
so that I could use this connection (pgsql-test):
'pgsql-test' => ['driver' => 'pgsql','url' => env('DATABASE_URL'),'host' => env('DB_HOST', '127.0.0.1'),'port' => env('DB_PORT', '5432'),'database' => env('DB_DATABASE', 'forge') . "_test",'username' => env('DB_USERNAME', 'forge'),'password' => env('DB_PASSWORD', ''),'charset' => 'utf8','prefix' => '','prefix_indexes' => true,'search_path' => 'public','sslmode' => 'prefer',],
without manually creating a database?

简单回答。不。你可以创建一个像评论中的一个命令，或者手动创建它。当第一次运行迁移时，你可能会被提示是否要创建模式。
英文:
Simple answer. No. You can create a command like one of the comments sais or create it manually. Also when running migrations first time, you may be prompted if you want the schema to be created.
