Joomla 3.x - About the SQL query field type limits

Joomla 3.x - About the SQL query field type limits a été créé par Michaël Brantus
Hello everyone !
I have a question about the SQL field type in the component creator.

I try to get a list of values and keys from a MySQL table
When I use this query in my SQL field

SELECT name, id FROM myTable ODER BY name

This query works fine with my component in Joomla 3.x


Now I need to add an empty value in my list using this query

SELECT name, id FROM myTable UNION '' as name, NULL as id ORDER BY name

This query works fine when i run it on PHPMyAdmin but now my component in Joomla 3.x does't work i only get a connexion error in my browser.

If someone have an idea to resolve this, I only want to add a blank line in my list

I reply to myself

When i modify the SQL query with my code editor it works !

It was just a problem with the quotes converted in html quotes
