Database Preparing

Package provides two way for preparing database:

1. Raw SQL. You can use it with the migration package used in your application.

   • Ensure tables:

     • MSSQL,
     • MySQL / MariaDB,
     • Oracle,
     • PostgreSQL
     • SQLite

   • Ensure no tables:

     • MSSQL,
     • MySQL / MariaDB,
     • Oracle,
     • PostgreSQL
     • SQLite

2. DbSchemaManager for ensureTable(), ensureNoTable() methods for log table (by default {{%yii_log}}).

// Create db schema manager
$dbSchemaManager = new DbSchemaManager($db);

// Ensure table with default name
$dbSchemaManager->ensureTable();

// Ensure table with custom name
$dbSchemaManager->ensureTable('{{%custom_log_table}}');

// Ensure no table with default name
$dbSchemaManager->ensureNoTable();

// Ensure no table with custom name
$dbSchemaManager->ensureNoTable('{{%custom_log_table}}');

General usage

When creating an instance of \Yiisoft\Log\Logger, you must pass an instance of the database connection.

Creating a target:

$dbTarget = new \Yiisoft\Log\Target\Db\DbTarget($db, $table);

• $db (\Yiisoft\Db\Connection\ConnectionInterface) - The database connection instance.
• $table (string) - The name of the database table to store the log messages. Defaults to "log".

Creating a logger:

$logger = new \Yiisoft\Log\Logger([$dbTarget]);

You can use multiple databases to store log messages:

/**
 * @var \Yiisoft\Db\Connection\ConnectionInterface $mysqlDb
 * @var \Yiisoft\Db\Connection\ConnectionInterface $sqliteDb
 */

$logger = new \Yiisoft\Log\Logger([
    new \Yiisoft\Log\Target\Db\DbTarget($mysqlDb),
    new \Yiisoft\Log\Target\Db\DbTarget($sqliteDb),
]);
