I'm trying to add a gender
column to my table with this query:
ALTER TABLE QRCodeUser ADD gender CHAR(1) enum('M','F') NOT NULL;
I get this 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 'enum('M','F') NOT NULL' at line 1
What's my mistake?
Try this (you dont need to specify the size, char(1)
) :
ALTER TABLE QRCodeUser ADD gender enum('M','F') NOT NULL;
