ĮND Code language: SQL (Structured Query Language) ( sql ) To create a new trigger in SQLite, you use the CREATE TRIGGER statement as follows: CREATE TRIGGER trigger_name In addition, you use triggers to enforce complex business rules centrally at the database level and prevent invalid transactions. For example, you want to log the changes in the sensitive data such as salary and address whenever it changes. You often use triggers to enable sophisticated auditing. What is an SQLite triggerĪn SQLite trigger is a named database object that is executed automatically when an INSERT, UPDATE or DELETE statement is issued against the associated table. The DB facade provides methods for each type of query: select, update, insert, delete, and statement.Summary: this tutorial discusses SQLite trigger, which is a database object fired automatically when the data in a table is changed. Once you have configured your database connection, you may run queries using the DB facade. It is up to you to decide if this is the desired behavior for your application. This ensures that any data written during the request cycle can be immediately read back from the database during that same request. If the sticky option is enabled and a 'write' operation has been performed against the database during the current request cycle, any further 'read' operations will use the 'write' connection. The sticky option is an optional value that can be used to allow the immediate reading of records that have been written to the database during the current request cycle. When multiple values exist in the host configuration array, a database host will be randomly chosen for each request. The database credentials, prefix, character set, and all other options in the main mysql array will be shared across both connections. So, in this case, 192.168.1.1 will be used as the host for the 'read' connection, while 192.168.1.3 will be used for the 'write' connection. You only need to place items in the read and write arrays if you wish to override the values from the main mysql array. The rest of the database options for the read and write connections will be merged from the main mysql configuration array. The read and write keys have array values containing a single key: host. Note that three keys have been added to the configuration array: read, write and sticky. After the database has been created, you may easily configure your environment variables to point to this database by placing the absolute path to the database in the DB_DATABASE environment variable: You can create a new SQLite database using the touch command in your terminal: touch database/database.sqlite.

SQLite databases are contained within a single file on your filesystem.

However, you are free to modify your database configuration as needed for your local database. Examples for most of Laravel's supported database systems are provided in this file.īy default, Laravel's sample environment configuration is ready to use with Laravel Sail, which is a Docker configuration for developing Laravel applications on your local machine. Most of the configuration options within this file are driven by the values of your application's environment variables. In this file, you may define all of your database connections, as well as specify which connection should be used by default. The configuration for Laravel's database services is located in your application's config/database.php configuration file.
