學習yii2框架刪除資料庫操作的方法

根據id刪除

deleteall() 刪除多個

$model

= user:
:find
($id);
$model
->
delete()
;

$connection

->
createcommand()
->
delete
('qipa250_user'
,'status = 0')-
>
execute()
;

$connection

->
createcommand
('delete from qipa250_user where userid=:userid')-
>
execute()
;

$model

=$connection
->
createcommand
('delete from qipa250_user where userid=:userid');
$model
->
bindparam
(':userid'
,$userid);
$userid=5
;$model
->
execute()
;

$model

=$connection
->
createcommand
('delete from qipa250_user where userid=:userid');
$model
->
bindparam
(':userid'
,$userid);
// delete user 1
$userid=1
;$model
->
execute()
;// delete user 2
$userid=2
;$model
->
execute()
;

$user

= user:
:findone(2
);$user
->
delete()
;或者user:
:findone(2
)->
delete()
;// 輸出語句
// delete from `qipa250_user` where `id`='2'

user:

:deleteall
('status = :status and age > :age',[
':age'
=>20,
':status'
=>
'active'])
;//output query
//delete from `qipa250_user` where status = 'active' and age > 20

user:

:deleteall([
'and'
,'type = :type_id',[
'not in'
,'usercategoryid'
,$categorieslist]]
,[':type_id'
=>2]
);//output query
//delete from `qipa250_user` where (type = 2) and (`usercategoryid` not in (1, 2, 3))

基礎YII2資料庫操作

注意 為了保持精度，從資料庫中取出的資料都被表示為字串，即使相應的資料庫列型別數值。當建立從乙個帶引數的sql乙個db命令，你應該總是使用繫結引數的方法來防止sql注入攻擊。引數繫結是通過預處理語句來實現。除了防止sql注入攻擊，也可通過一次準備sql語句和多次使用不同的引數執行它提高效能 yii ...
