我们使用Doctrine,一个PHP ORM。我创建了一个这样的查询:
$q = Doctrine_Query::create()->select('id')->from('MyTable');
然后在函数中,我添加了各种where子句和适当的东西,像这样
$q->where('normalisedname = ? OR name = ?', array($string, $originalString));
稍后,在execute()-ing该查询对象之前,我想打印出原始SQL以检查它,并这样做:
$q->getSQLQuery();
但是,这只打印准备好的语句,而不是完整的查询。我想看看它正在发送什么到MySQL,但相反,它正在打印一个准备好的语句,包括?是否有一些方法可以看到'full'查询?
我已经创建了一个Doctrine2 Logger,它就是这样做的。它使用Doctrine 2自己的数据类型转换器将参数化sql查询与值“水合”起来。

下面的代码将在标准输出中返回使用$em实体管理器生成的任何INSERT,UPDATE,DELETE SQL语句,
/**@var \Doctrine\ORM\EntityManager $em */
$em->getConnection()

修改了@dsamblas函数,当参数是日期字符串(如'2019-01-01')时工作,并且当有使用IN传递的数组时工作
$qb->expr()->in('ps.code', ':activeCodes'),
. 所以做dsamblas写的所有事情,但是用这个替换startQuery,或者看看区别,然后添加我的代码。(以防他修改了他的功能,而我的版本没有修改)。
public function startQuery($sql, array $params = null, array $types = null)
{
if($this->isLoggable($sql)){
if(!empty($params)){
foreach ($params as $key=>$param) {
try {
$type=Type::getType($types[$key]);
$value=$type->convertToDatabaseValue($param,$this->dbPlatform);
} catch (Exception $e) {
if (is_array($param)) {
// connect arrays like ("A", "R", "C") for SQL IN
$value = '"' . implode('","', $param) . '"';
} else {
$value = $param; // case when there are date strings
}
}
$sql = join(var_export($value, true), explode('?', $sql, 2));
}
}
echo $sql . " ;".PHP_EOL;
}
}
没有测试太多。
