Why does this ALTER TABLE query throw syntax error?

Question

This is the query I'm using:

ALTER TABLE apartment ADD technical TEXT NOT NULL AFTER is_sale

Why does it produce a syntax error?

EDIT:

ALTER TABLE apartment ADD COLUMN technical TEXT NOT NULL AFTER is_sale still produces an error:

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 'ALTER TABLE andreevka_apartment ADD COLUMN technincal TEXT NOT NULL AFTER' at line 1

Answer 1

It actually turned out that my query was copy-pasted from PhpMyAdmin and had some encoding issues. I pasted it into Notepad++, converted it to ANSI and it worked. Weird.

The syntax was perfectly fine.
