Getting a raw SQL query with variables in Yii1 - mysql

Question

Is Yii1 has any native methods to get the raw SQL with variables built?
I try to get a complex query built on a few subqueries using CDbExpression and CommandBuilder. I got this as a result:
SELECT * FROM `news` `t` WHERE id IN (:ycp0, :ycp1, :ycp2, :ycp3, :ycp4) LIMIT 5
The dump of the criteria content:
CDbCriteria Object (
[select] => *
[condition] => id IN (:ycp0, :ycp1, :ycp2, :ycp3, :ycp4)
...
[params] => Array(
[:ycp0] => CDbExpression Object(
[expression] => SELECT id FROM `news` `t` WHERE (rubric=:rb1) AND (:im2 & `im`=:im2) LIMIT 1
[params] => Array(
[:rb1] => 1
[:im2] => 2
)
)
...
)
)
I expected for compiled query string like this:
SELECT * FROM .. WHERE id IN(
(SELECT id FROM .. WHERE .. ORDER BY .. LIMIT 1),
(SELECT id FROM .. WHERE .. ORDER BY .. LIMIT 1)
) ORDER BY .. LIMIT 5
This is what I do in my code
$criteria = new CDbCriteria( ... );
$sql = $this->commandBuilder->createFindCommand($tableName, $criteria)->getText();
$queries[] = new CDbExpression($sql, $criteria->params);
Then I try to combine subqueries to one complex query
$criteria = new CDbCriteria( ... );
$criteria->addInCondition('id', $queries);
And finally, I try to get the result as SQL-query
$sql = $this->commandBuilder->createFindCommand($tableName, $criteria)->getText();

Answer 1

You get the SQL with params, as you have
$sql = $this->commandBuilder->createFindCommand($tableName, $criteria)->getText();
Then get the params enclosed in quotes:
$params = array_map(function($param) { return '"' . $param . '"'; }, $criteria->params);
Finally, replace the pairs:
echo strtr($sql, $params);

You can use enableParamLogging in your db config (boolean). You can set it up so it's used conditionally -- make sure to not use it in production.
'db' => [
'connectionString' => 'mysql:host=' . $dbhost . ';port=' . $dbport . ';dbname=' . $dbname,
'emulatePrepare' => true,
'username' => $db_user,
'password' => $db_pass,
'schemaCachingDuration' => 3600,
'charset' => 'utf8',
'enableProfiling' => $db_profile,
'enableParamLogging' => $db_params,
],
Then you can add 'class'=>'CWebLogRoute' to your log routes if you want to see all the output in your browser. docs

Answer 3

I think you want to do something like this:
$criteria = ...;
$command = $builder->createFindCommand($schema->getTable('name_of_table'), $criteria);
$results = $command->text;

Answer 4

There are few other options to perform the same thing but i will suggest you
should use the following
$results = MyModel::model()->findAllBySql("...");
Or you can prefer the following :
