Yii1 equivalent of the Sql query

Question

I have this sql query

SELECT * FROM form_fields 
WHERE id NOT IN ("3", "1", "6") 
ORDER BY FIELD (id, "3" ,"1" ,"6")

which i want to convert to an yii1 query. So i tried like this

$SQL="SELECT * FROM form_fields WHERE id NOT IN {$sorted_array}  ORDER BY FIELD (id, $sorted_array)";
$connection=Yii::app()->db; 
$command=$connection->createCommand($SQL);
$rowCount=$command->execute(); 
$dataReader=$command->query(); 

where $sorted_array has value Array ( [0] => 3 [1] => 1 [2] => 6 )

It gave me an error

PHP notice

Array to string conversion

then i converted the $sorted_array to string like this

$string = implode(' ', $sorted_array);

and again executed the query

$SQL="SELECT * FROM form_fields WHERE id NOT IN {$string}  ORDER BY FIELD (id, $string)";
$connection=Yii::app()->db; 
$command=$connection->createCommand($SQL);
$rowCount=$command->execute(); 
$dataReader=$command->query(); 

Now i get another error

CDbException

CDbCommand failed to execute the SQL statement: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '3 1 6 ORDER BY FIELD (id, 3 1 6)' at line 1. The SQL statement executed was: SELECT * FROM form_fields WHERE id NOT IN 3 1 6 ORDER BY FIELD (id, 3 1 6)

Instead of this

SELECT * FROM form_fields 
    WHERE id NOT IN ("3", "1", "6") 
    ORDER BY FIELD (id, "3" ,"1" ,"6")

my yii1 query produced this erroneous sql query

SELECT * FROM form_fields
WHERE id NOT IN 3 1 6 ORDER BY FIELD (id, 3 1 6)

Any help would be appreciated

Answer 1

implode的第一个参数应该是逗号：

$string = implode(',', $sorted_array);

Answer 2

The better way is use QueryBuilder. It looks like

$result = Yii::app()->db->createCommand()
              ->select('field1, field2')
              ->from('table t')
              ->join('table2 t2', 't2.t_id = t.id')
              ->where('t.property = :property', [':property' => 1])
              ->queryRow();

It's more useful, because QueryBuilder use PDO-statements for parameters, and makes correct queries in SQL dialect which depends of your DBMS type.

It also supports array statements, like this:

->where(['in', 'field', [1,2,3]])

The result is:

... WHERE field IN (1, 2, 3) ...

And yes, it's still DAO, without ActiveRecord :)
