how can I increment a value?
$app->db->update('videos', array(
'views' => 'views + 1'
), array(
'id' => $id
));
It doesn't work in many ways I tried.
A better approach could be to use the method executeUpdate()
$app->db->executeUpdate("UPDATE videos SET views=views+1 WHERE id=?", array($id));
Edit 2022
The API is working but marked deprecated. Use executeStatement() instead of executeUpdate()
You have to ask the db for the current value of views first, then increment the value and save the new value into db.
$result = $app->db->fetchAssoc('SELECT views FROM videos WHERE id = ?', array($id));
$result['views']++;
$app->db->update('videos', array('views' => $result['views']), array('id' => $id));

I am trying to increment a column and updateorcreate a record in one query by doing so:
$model = Model::updateOrCreate([
'email' => $email
], ['received_at' => $received_at])->incremet('received_count');
This does the job as I wanted it too. It updates or create a record and increments the received_count column.
But after the query, I wanted to get the updated/created row, but when I log $model, it only logs 0 or 1. I can confirm that this is because of the ->increment().
But to be honest, I don't know any way how to increment the received_count column other than how I currently did it.
How do I achieve so that it updates or create a record, at the same time increments the received_count column, and after all of this, returns the updated/created object?
As much as posssible, I want this all in one query. Getting the model should be a memory.
$model = Model::updateOrCreate(['email' => $email], ['received_at' => $received_at]);
$model->increment('received_count');
$model->refresh(); // this will refresh all information for your model.
or you can simply:
$model = Model::updateOrCreate(['email' => $email], ['received_at' => $received_at]);
tap($model)->increment('id'); // this will return refreshed model.
just fresh model after incremet:
$model = Model::updateOrCreate([
'email' => $email
], ['received_at' => $received_at]);
$model->incremet('received_count');
$model->fresh();
i am trying to pass some values into a single column in laravel database table.
The values are like this 20,45,67,89
but i want them to enter into the colume like this
===USER_ID====
20
45
67
89
I have tried like below, but not working..any suggestions ?
foreach ($request->val2 as $value){
$str_explode = explode(",",$value);
DB::table('retirement')->insertGetId([
'user_id' => $str_explode,
'amount' => $request->val1,
'week' => $request->week
]);
}
Hope this will work
foreach ($request->val2 as $value){
$str_explode = explode(",",$value);
$insert = [];
foreach($str_explode as $str){
$insert[] = [
'user_id' => $str,
'amount' => $request->val1,
'week' => $request->week
];
}
DB::table('retirement')->insert($insert);
I'm not sure i understood your question clearly, i'm assuming you want to insert array to a column:
did you try to set the column in migration to Json?
did you set the $casts in the model to json or array?
protected $casts = [ 'user_id' => 'array' ];
then when you do this, you can have an array added to that column like
Posts::create(['user_id'=>[1,2,3,4]]);
normally the user_id field is set to unsignedBigInt(), that type will not accept anything but integers, you gotta check the migration column type first.
explode() is returning an array, not a single value, that's why it will fail. Instead, you should loop through all values like this:
foreach ($request->val2 as $value){
$str_explode = explode(",",$value);
foreach($str_explode as $str){
DB::table('retirement')->insertGetId([
'user_id' => $str,
'amount' => $request->val1,
'week' => $request->week
]);
}
}
As a side advice, as you are not saving the id returned by insertGetID, you can simply use insert. Moreover, it's usually a good practice to use create because this way you will also save timestamps for created and updated.
I don't get the difference between query builder's Replace and Update. Especially the documentation for Replace...
This method executes a REPLACE statement, which is basically the SQL standard for (optional) DELETE + INSERT, using PRIMARY and UNIQUE keys as the determining factor.
...but I see no indication of using a PK in the example. Am I missing some fundamental knowledge here? (I understand Update just fine).
Replace
$data = array(
'title' => 'My title',
'name' => 'My Name',
'date' => 'My date'
);
$this->db->replace('table', $data);
Update
$data = array(
'title' => $title,
'name' => $name,
'date' => $date
);
$this->db->where('id', $id);
$this->db->update('mytable', $data);
Thanks.
REPLACE
It's like insert. but if the primary key being inserted is the same one as another one, the old one will be deleted and the new one will be inserted.
UPDATE
Updates the current row that you tried to update.
Does anyone know how to properly insert new content categories to the DB programatically?
For each post in the categories table, there is also a post saved in the assets table with lft and rgt set.
Is there any native Joomla class I can use for this instead of plain SQL?
Please Please Only use the native classes, which categories will handle for you seamlessly. As soon as you add categories the whole thing will be handled automagically. Just look at any core component to see how.
It is not easy to update the assets table using sql, it is all very specifically managed and part of a complex series of foreign keyed tables.
Extend JTable or JTableContent to handle this.
Here is some code I just whipped together that just uses the JTableCategory class, so it can be used simply on the front or admin side of Joomla
$table = JTable::getInstance('category');
$data = array();
// name the category
$data['title'] = $title;
// set the parent category for the new category
$data['parent_id'] = $parent_id;
// set what extension the category is for
$data['extension'] = $extension;
// Set the category to be published by default
$data['published'] = 1;
// setLocation uses the parent_id and updates the nesting columns correctly
$table->setLocation($data['parent_id'], 'last-child');
// push our data into the table object
$table->bind($data);
// some data checks including setting the alias based on the name
if ($table->check()) {
// and store it!
$table->store();
// Success
} else {
// Error
}
Naturally you would want to get the data pieces set correctly, but these are the core ones to set.
Here is a function I've created just for this purpose, after some digging & experimenting.
It uses core classes, so it needs an access to them (for me it's basically a part of Joomla component).
Mind, it's for Joomla 3, for Joomla 2.5 and before, you need to change JModelLegacy to JModel.
function createCategory( $name, $parent_id, $note )
{
JTable::addIncludePath( JPATH_ADMINISTRATOR . '/components/com_categories/tables' );
$cat_model = JModelLegacy::getInstance( 'Category', 'CategoriesModel' );
$data = array (
'id' => 0,
'parent_id' => $parent_id,
'extension' => 'com_content',
'title' => $name,
'alias' => '',
'note' => $note,
'description' => '',
'published' => '1',
'access' => '1',
'metadesc' => '',
'metakey' => '',
'created_user_id' => '0',
'language' => '*',
'rules' => array(
'core.create' => array(),
'core.delete' => array(),
'core.edit' => array(),
'core.edit.state' => array(),
'core.edit.own' => array(),
),
'params' => array(
'category_layout' => '',
'image' => '',
),
'metadata' => array(
'author' => '',
'robots' => '',
),
);
if( !$cat_model->save( $data ) )
{
return NULL;
}
$categories = JCategories::getInstance( 'Content' );
$subcategory = $categories->get( $cat_model->getState( "category.id" ) );
return $subcategory;
}
You can perhaps use the save() in category.php file.
File location: root\administrator\components\com_categories\models\category.php
It saves the form data supplied to it!
The JOS_assets table is to store the ACL for each asset that is created.
If you do not update this table while programatically creating the category, the default ACL will apply. And when later you open and save the category in the administrative panel, the ACL will be updated as it should have been by core Joomla!.
You can create an SQL query very easily though and update the asset table as well. Its easy to understand once you open the table's content in phpmyadmin.
I am trying to add an entry to an Oracle table which has a date field. So far, I've only been able to do it like this:
$createdDate = $entry->createdDate->toString('yyyy-MM-dd');
$data = array(
'ID' => $entry->id,
'STATE' => $entry->state,
'CREATED_DATE' => new Zend_Db_Expr("to_date('$createdDate', 'YYYY-MM-DD')")
);
$this->_getGateway()->insert($data);
Is there a better way? This solution smells dirty to me.
You should be able to do this instead:
$createdDate = $entry->createdDate->toString('yyyy-MM-dd');
$data = array(
'ID' => $entry->id,
'STATE' => $entry->state,
'CREATED_DATE' => new Zend_Db_Expr("date '$createdDate'")
);
$this->_getGateway()->insert($data);
The only difference is the use of an ANSI date literal in line 5.
