Many customers approached us with the error, 'sqlstate[42000] syntax error or access violation'.

On detailed analysis, we could trace that in most cases the error happens due to the wrong syntax entry.


Some common syntax mistakes we investigated are listed as following.


Missing parenthesis

One of our customers approached us with the error ‘sqlstate[42000] syntax error or access violation’. On further analysis with the code, we traced that, the problem arose due to missing parenthesis.

For instance, the code is as follows:

B::query(Database::SELECT, 'SELECT COUNT(*) as `count`,`region`, MONTHNAME(`date`) as`month`
FROM tempur_stores.stats
WHERE `date` > DATE_ADD(DATE(NOW()), INTERVAL -1 WEEK)
AND `date` < DATE(NOW())
GROUP BY `region`, MONTH(`date`');

Here, in the last line, we could see that a missing parenthesis ‘)’. We then Just put a parenthesis ) before that apostrophe(after ‘date’) and the error got fixed.


Missing backticks (`)

Another customer was facing the same error after adding details to the database.

After going through the code we traced that in the syntax there were missing backticks at relevant places.

For instance, a small part of the code is as follows:

$query1 = "INSERT INTO order (order_details, order_address, customer_id, customer_name, delivery_type, paid) VALUES(:details,:address,:d,:name,:delivery,:paid);";
$sql=$conn->prepare($query1);
$sql->bindParam(':details', $details);

Here, the order is a reserved keyword. We have to add backticks ` around it to use it. After adding the backticks, the code worked properly.


Extra space or no space
