mysql - PDO Error - Syntax error or access violation: 1064

I am trying to run a query but it looks like I am conflicting with a reserved keyword. I can't figure out where the conflict is. I am relatively new to this, so any help would be appreciated.



I have already tried changing all 'row' to 'my_row' - it didn't seem to make a difference.



My code:




        $substmt = $pdo->prepare('  SELECT 
`sentences_index`.`row_id` AS id,
`sentences_index`.`id` AS char_id,
`sentences_index`.`word`,
`definitions`.`pinyin`,
`definitions`.`def1` AS definition,
`sentences`.`sentenceEN`

FROM `sentences_index`
LEFT JOIN `definitions` ON `sentences_index`.`word` = `definitions`.`traditional`

LEFT JOIN `sentences` ON `sentences_index`.`row_id` = `sentences`.`id`

WHERE `sentences_index`.`row_id` = :row

GROUP BY `sentences_index`.`word`
ORDER BY char_id ASC
');
$substmt->execute(['row' => $row]);



Any help would be appreciated.



Edit: Here is the error message:




Fatal error: Uncaught PDOException: 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 'AS id, sentences_index.id AS char_id,
definitions.`p' at line 17 in

And I do understand there is a similar question. I have read it and tried to find the same problem in my code. I cannot find the problem, which is why I am asking this question.




Edit2: Interestingly, this error is not thrown in PHP 7.0.0 but is thrown in PHP 7.0.8
