[intrinsic column flags] - PK: primary key (column is part of a pk) - NN: not null (column is nullable) - UQ: unique (column is part of a unique key) - AI: auto increment (the column is auto incremented when rows are inserted) [additional data type flags, depend on used data type] - BIN: binary (if dt is a blob or similar, this indicates that is binary data, rather than text) - UN: unsigned (for integer types, see docs: "10.2. Numeric Types") - ZF: zero fill (rather a display related flag, see docs: "10.2. Numeric Types") MySQLでログを出力してみる ERROR 2049 (HY000): Connection using old (pre-4.1.1) authentication protocol refused (client option ‘secure_auth’ enabled) MySQLのバージョンがちがうとパスワードハッシュが違うのでログインできなくなる
