MySQL row declarations?

What do these mean in MySQL? I'm using MySQL workbench and I see I can specify a new column as these... (I noted my guesses)

• PK – (primary key)
• NN – (non null)
• BIN – (binary?)
• UN – (Unicode?)
• ZF- (???)
• AI – (autoincrement?)

Is AI 开发者_如何学Goexactly like an Identity specification in MSSQL? (Can I insert a record without specifying the value and it will insert the next available int?)

ZF is probably ZEROFILL:

CREATE TABLE zf (id INT(5) ZEROFILL NOT NULL DEFAULT 0);

INSERT
INTO    zf
VALUES  (1);

SELECT  *
FROM    zf;

--
00001

UN is not UNICODE, but UNSIGNED (ZEROFILL implies it)

NN means not null,

Yes you can insert that way.
