|
|||
|
|
* 1.

|
|||
|
|
* postgresql: GENERATED BY DEFAULT AS IDENTITY
|
|||
|
|
*
|
|||
|
|
* 2.
|
|||
|
|
* sqlite: datetime
|
|||
|
|
* postgresql: timestamp
|
|||
|
|
*
|
|||
|
|
* 3.
|
|||
|
|
* sqlite: update sqlite_sequence set seq = 1000 where name = 'sys_role' ;
|
|||
|
|
* postgresql: select setval('sys_role_id_seq', 1000);
|
|||
|
|
*
|
|||
|
|
* 4.
|
|||
|
|
* sqlite: "disabled" boolean DEFAULT (0)
|
|||
|
|
* postgresql: "disabled" boolean DEFAULT (false)
|
|||
|
|
*
|
|||
|
|
* 5.
|
|||
|
|
* sqlite: last_insert_rowid()
|
|||
|
|
* postgresql: LASTVAL()
|
|||
|
|
*
|
|||
|
|
* 6.
|
