Updating the records in to the cursor

Think of each Eloquent model as a powerful query builder allowing you to fluently query the database table associated with the model.For example: The first argument passed to the method is the number of records you wish to receive per "chunk".#simples IBM calls this type of update a positioned update.There is a way cooler, big data selection that we could do updating the whole set-at-a-time also called a searched update.The Eloquent ORM included with Laravel provides a beautiful, simple Active Record implementation for working with your database.Each database table has a corresponding "Model" which is used to interact with that table.

So, I am not going to give any excuse for my lack of comments… 🙂 So, now lets update that exact same program and change it to use SQL to do the exact same thing.

When we want to update or delete the cursor fetched row(s) from the database, we don’t have to form In the below code listing, the employees joined before the year 2000 are archived and during the cursor process, no other session is permitted to make any changes to those employees using the FOR UPDATE clause.

The employee deletion from the transaction table is performed using the WHERE CURRENT OF clause as shown below.

The attribute on the model, as all Eloquent models protect against mass-assignment by default.

A mass-assignment vulnerability occurs when a user passes an unexpected HTTP parameter through a request, and that parameter changes a column in your database you did not expect.
