Beego orm 模型字段與數據庫類型的對應

深度學習，ORM 推薦的對應數據庫類型，在此列出，自動建表功能也會以此為標准。默認所有的字段都是 NOT NULL

MySQL

go	mysql
int, int32-設置auto或者名稱為Id	integer AUTO_INCREMENT
int64-設置auto或者名稱為Id	bigint AUTO_INCREMENT
uint, uint32 - 設置 auto 或者名稱為 Id	integer unsigned AUTO_INCREMENT
uint64 - 設置 auto 或者名稱為 Id	bigint unsigned AUTO_INCREMENT
bool	bool
string - 默認為 size 255	varchar(size)
string - 設置 type(text)	longtext
time.Time-設置 type為date	date
time.Time	datetime
byte	tinyint unsigned
rune	integer
int	integer
int8	tinyint
int16	smallint
int32	integer
int64	bigint
uint	integer unsigned
uint8	tinyint unsigned
uint16	smallint unsigned
uint32	integer unsigned
uint64	bigint unsigned
float32	double precision
float64	double precision
float64 設置digits,decimals	numeric(digits, decimals)
