You need ADD COLUMN clauses for those other two columns. Perhaps this ALTER TABLE statement was edited from a CREATE TABLE statement incorrectly? On Apr 17, 2017 2:48 PM, "Justin Swanhart" <greenlion@gmail.com> wrote:
I believe there is a missing right parenthesis after the 11. has_children is a third Boolean column.

I've used Mariadb for a couple of small projects. I prefer to automate as much of the initial creation and config as possible, using SQL scripts executed from JDBC. I can at least do this for the table creation and population.
I'm taking over an existing small project that is organized somewhat funky. There are some scripts that are apparently intended to initialize the database, but I'm seeing one line in one of those scripts that I don't understand, and I don't think is valid.
I would appreciate some help explaining what you think this line MIGHT be intending to do: ----------------- ALTER TABLE `project` add column (proj_typ_id TINYINT(2) NOT NULL DEFAULT 1, parent_proj_id int(11, has_children BOOLEAN); -----------------
The first problem is that first paren. There's no matching right paren, so I can't imagine this can succeed.
Second, I don't understand much past that first comma. Is this intending to add TWO columns, the second being "parent_proj_id"? Assuming that's the case, what exactly does "int(11, has_children BOOLEAN)" mean? I can see that it's declaring an 11-digit int, but I don't understand the "has_children" part.
