In MySQL we can create queries with or without the backtick (`) symbol. Example:


SELECT * FROM TEST;
SELECT * FROM `TEST`;


Both works fine in mysql-console.

Is there any technical difference between them?

Is there any benefit using (`) over over simple queries?

They are called quoted identifiers and they tell the parser to handle the text between them as a literal string. They are useful for when you have a column or table that contains a keyword or space. For instance the following would not work:

CREATE TABLE my table (id INT);


But the following would:

CREATE TABLE `my table` (id INT);


Also, the following would get an error, because COUNT is a reserved keyword:

SELECT count FROM some_table


But the following would be parsed correctly:

SELECT `count` FROM some_table


I hope this helps you.
