DDC-2555: Syntax Error when column is "separator"

[doctrinebot]

Jira issue originally created by user dallas62:

I had to made a column called "separator", 'Create Table' works, but when 'insert into':

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 'separator) VALUES ('Test', 'Test', 'a:1:{i:0;s:4:"test";}', 'a:5:{s:10:"http-' at line 1

After some searches ... Separator used by MySQL, so i changed the name:

php app/console d:s:u --force
Updating database schema...

[Doctrine\DBAL\DBALException]
An exception occurred while executing 'ALTER TABLE seo CHANGE separator link_separator VARCHAR(255) DEFAULT NULL':

[PDOException]

Same Error... I will manualy update but for me it's a bug ...

Reserved SQL keywords need manual escaping by either using a custom quoting strategy or by marking the table name with backticks in mappings, such as: "separator"

The ORM is not responsible for escaping identifiers out of the box.

I have never writen any SQL Request for this error
Only Doctrine, I re-use the request with ` but Doctrine create the table, the insert and alter the table

Create table: no error
Insert into: error
Alter table: error

use Doctrine\ORM\Mapping as ORM;
[...]
/****

• @Orm\Column(name="separator", type="string", nullable=true)

[~dallas62] that's actually a problem in the DBAL layer. it should have failed during DDL execution
