问题
Why I try to do an order by query, I always get an error telling me to check the syntax by the ORDER BY 'order' DESC.... Here's my query:
SELECT * FROM posts ORDER BY order DESC;
What am I doing wrong??
回答1:
order is a reserved word in SQL; case does not matter. It must be quoted when used as an identifier. From the MySQL Reserved Words documentation:
Certain words such as SELECT, DELETE, or BIGINT [or ORDER] are reserved and require special treatment for use as identifiers such as table and column names.
Traditional MySQL quotes:
SELECT * FROM posts ORDER BY `order` DESC;
Proper (ANSI) SQL quotes (some databases support [order] as well):
SELECT * FROM posts ORDER BY "order" DESC;
Although I would consider renaming the column to avoid such confusing issues in the future.
Happy coding!
回答2:
Order is reserved keyword.
Try,
SELECT * FROM posts ORDER BY `order` DESC;
回答3:
The column name is order which is a keyword. You need to do this:
SELECT * FROM posts ORDER BY `order` DESC;
