This article mainly introduces the addition, deletion, modification and checking of Yii framework. It has certain reference value. Now I share it with everyone. Friends in need can refer to it

1. Query data

1. findAll (query a collection based on a condition)

$admin=Admin::model()->findAll($condition,$params);

$admin=Admin::model()->findAll("username=:name",array(":name"=>$username));

$admin=Admin::model()->findAll(“username=:name and age=:age” , array(“:name”=>$name, “age”=>$age));
 
$admin=Admin::model()->findAll(“username like :name and age=:age” , array(“:name”=>$name, “age”=>$age));
 
$infoArr= NewsList::model()->findAll("status = &#39;1&#39; ORDER BY id DESC limit 10 ");

2. findAllByPk (query a collection based on the primary key, multiple primary keys can be used)

$admin=Admin::model()->findAllByPk($postIDs,$condition,$params);

$admin=Admin::model()->findAllByPk($id,"name like :name and age=:age",array(&#39;:name&#39;=>$name,&#39;age&#39;=>$age));
 
$admin=Admin::model()->findAllByPk(array(1,2));

Copy after login

3. findAllByAttributes (query a collection based on conditions, which can be multiple conditions, and put the conditions into the array)

$admin=Admin::model()->findAllByAttributes($attributes,$condition,$params);
 
$admin=Admin::model()->findAllByAttributes(array(&#39;username&#39;=>&#39;admin&#39;));

Copy after login

4. findAllBySql( Query an array based on the SQL statement)

$admin=Admin::model()->findAllBySql($sql,$params);

$admin=Admin::model()->findAllBySql("select * from admin where username like :name",array(&#39;:name&#39;=>&#39;%ad%&#39;));

Copy after login

5. findByPk(Query an object based on the primary key)

$admin=Admin::model()->findByPk($postID,$condition,$params);

$admin=Admin::model()->findByPk(1);

Copy after login

6. find (query a set of data based on a condition, there may be multiple data, only the first row of data is returned)

$row=Admin::model()->find($condition,$params);

$row=Admin::model()->find(&#39;username=:name&#39;,array(&#39;:name&#39;=>&#39;admin&#39;));

Copy after login

7. findByAttributes (query a set of data based on conditions, which can be multiple conditions, put the conditions into the array, and query the first piece of data)

$admin=Admin::model()->findByAttributes($attributes,$condition,$params);

$admin=Admin::model()->findByAttributes(array(&#39;username&#39;=>&#39;admin&#39;));

Copy after login

8 , findBySql (query a set of data based on SQL statements, query the first data)

$admin=Admin::model()->findBySql($sql,$params);

$admin=Admin::model()->findBySql("select * from admin where username=:name",array(&#39;:name&#39;=>&#39;admin&#39;));

Copy after login

9, count (query how many records there are in a collection based on a condition , returns an int type number)

$count=Post::model()->count($condition,$params);

$count=Post::model()->count("username=:name",array(":name"=>$username));

Copy after login

10. countBySql (queries how many records a collection has according to the SQL statement and returns an int type number)

$count=Post::model()->countBySql($sql,$params);

$count=Post::model()->countBySql("select * from admin where username=:name",array(&#39;:name&#39;=>&#39;admin&#39;));

Copy after login

11. exists (query according to a condition to see if the array obtained has data. If there is data, return a true, otherwise it is not found)

$exists=Post::model()->exists($condition,$params);

$exists=Post::model()->exists("name=:name",array(":name"=>$username));

Copy after login

2. Add data

save(add data)

$admin=new Admin;       

$admin->username =$username;

$admin->password =$password;

if($admin->save() > 0){echo"添加成功"; }else{echo"添加失败"; }

Copy after login

3. Modify data

update($pk primary key, which can be one or a set, $attributes is the set of fields to be modified, $condition, the value passed in by $params)

Post::model()->updateAll($attributes,$condition,$params);

$count=Admin::model()->updateAll(array(&#39;username&#39;=>&#39;11111&#39;,&#39;password&#39;=>&#39;11111&#39;),&#39;password=:pass&#39;,array(&#39;:pass&#39;=>&#39;1111a1&#39;));

if($count> 0){echo "修改成功"; }else{echo"修改失败"; }

$result=PostList::model()->updateAll(array(&#39;status&#39;=>&#39;1&#39;),&#39;staff_id=:staff and host_id=:host&#39;,array(&#39;:staff&#39;=>$staff_id,&#39;:host&#39;=>$host_id))

Copy after login

Post::model()->updateByPk($pk,$attributes,$condition,$params);

$count=Admin::model()->updateByPk(1,array(&#39;username&#39;=>&#39;admin&#39;,&#39;password&#39;=>&#39;admin&#39;));

$count=Admin::model()->updateByPk(array(1,2),array(&#39;username&#39;=>&#39;admin&#39;,&#39;password&#39;=>&#39;admin&#39;),&#39;username=:name&#39;,array(&#39;:name&#39;=>&#39;admin&#39;));

if($count>0){echo"修改成功"; }else{echo"修改失败"; }
 
Post::model()->updateCounters($counters,$condition,$params);

$count=Admin::model()->updateCounters(array(&#39;status&#39;=>1),&#39;username=:name&#39;,array(&#39;:name&#39;=>&#39;admin&#39;));

if($count> 0){echo "修改成功"; }else{echo"修改失败"; }

array ('status'=>1) represents the admin table in the database. According to the condition username='admin', the status field of all query results will be incremented by 1

4. Delete data

delete

Post::model()->deleteAll($condition,$params);

$count=Admin::model()->deleteAll(&#39;username=:nameandpassword=:pass&#39;,array(&#39;:name&#39;=>&#39;admin&#39;,&#39;:pass&#39;=>&#39;admin&#39;));

$count= Admin::model()->deleteAll(&#39;id in("1,2,3")&#39;);//删除id为这些的数据

if($count>0){echo"删除成功"; }else{echo"删除失败"; }
 
Post::model()->deleteByPk($pk,$condition,$params);

$count= Admin::model()->deleteByPk(1);

$count=Admin::model()->deleteByPk(array(1,2),&#39;username=:name&#39;,array(&#39;:name&#39;=>&#39;admin&#39;));

if($count>0){echo"删除成功"; }else{echo"删除失败"; }

Copy after login

5. createCommand

$sql="SELECT u.account,i.* FROM sys_user as u left join user_info as i on u.id=i.user_id";

$rows=Yii::app()->db->createCommand($sql)->query();

foreach($rowsas $k => $v){

    echo$v[&#39;add_time&#39;];

}

Copy after login

6. Transaction processing

$dbTrans= Yii::app()->db->beginTransaction();

try{    

    $post=new Post;

    $post->&#39;title&#39;=&#39;Hello dodobook!!!&#39;;

if(!$post->save()){

throw new Exception("Error Processing Request", 1);

}

    $dbTrans->commit();

    $this->_end(0,&#39;添加成功!!!&#39;);
