mysql – 获取yii中的所有表名

如何获取yii中的所有表名？

MysqL中的SQL查询是SHOW TABLES.
我试过了：

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

它抛出一个错误：

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 

解决方法:

试试这个：

$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/>';
}
