Question

phpmyadmin query not work for single quote / apostrophe.

Not Work

ALTER TABLE 'about_team' CHANGE 'position' 'pp' INT( 11 ) NOT NULL

Work:

ALTER TABLE `about_team` CHANGE `position` `pp` INT( 11 ) NOT NULL

Same query but not work, gives error:

#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 ”about_team’ CHANGE ‘position’ ‘pp’ INT(11) NOT NULL’ at line 1

Answer 1

it is because when you using single quote, it just means it is a STRING. Whereas BACTICK (the second query) means escaping a column.

'about_team' is not equal with `about_team`

'about_team' is STRING
`about_team` is a Table Name

Actually backticks enclosing the names are optional since the names used where not on MySQL Reserved Keyword List.

• MySQL Reserved Keywords

Usually, single quotes are used around values while backticks are for table names and column names.
