Question

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);

它会抛出错误：

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

Answer 1

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/>';
}

如果你想使用yii，那么Mani的回答是正确的。如果要使用create命令获取表名，则可以使用

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

Answer 3

简单就是这么简单：

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