How to update all rows in a column in codeigniter?

To update all rows in a column in CodeIgniter, you can use the update method of the database query builder class. Here's an example of how you can update all rows in a column in CodeIgniter:

1
2
3
4
5
6

$data = array(
    'column_name' => 'new_value'
);

$this->db->update('table_name', $data);

In the above code snippet, replace 'column_name' with the name of the column you want to update and 'new_value' with the new value you want to set for that column. Replace 'table_name' with the name of the table where the column exists.

Make sure to load the database library before running this code. You can load the database library in your controller or model constructor like this:

1

$this->load->database();

This will update all rows in the specified column in the table with the new value.
