Get all table names in yii

问题

How to get all table names in yii?

The sql query in mySQL is SHOW TABLES. I tried:

$sql = 'SHOW TABLES';
$tables = Yii::app()->db
         ->createCommand($sql)
         ->queryAll();
print_r($tables);

It throws an error:

CDbCommand failed to execute the SQL statement:
CDbCommand failed to prepare the SQL statement:
SQLSTATE[HY000]: General error: 1 near "SHOW": syntax error.
The SQL statement executed was: SHOW TABLES

try this one:

$connection = Yii::app()->db;//get connection
$dbSchema = $connection->schema;
//or $connection->getSchema();
$tables = $dbSchema->getTables();//returns array of tbl schema's
foreach($tables as $tbl)
{
    echo $tbl->rawName, ':<br/>', implode(', ', $tbl->columnNames), '<br/>';
}

If you want to use yii then Mani`s answer is correct. If you want to get table names using create Command then you can use

$sql='SELECT * FROM INFORMATION_SCHEMA.TABLES'
$tables = Yii::app()->db
         ->createCommand($sql)
         ->queryAll();

The simple is simple:

var_dump(Yii::app()->db->schema->getTableNames();
