$this->db->select(). Permits you to write the SELECT portion of your query: $this->db->select('title, content, date'); $query = $this->db->get('mytable'); // Executes: SELECT title, content, date FROM mytable. Note. If you are selecting all (*) from a table you do not need to use this function. When omitted, CodeIgniter assumes
This query can be called two ways: 1. You can supply the table name and call it from the $this->db-> object: $fields = $this->db->list_fields('table_name'); foreach ($fields as $field) { echo $field; }. 2. You can gather the field names associated with any query you run by calling the function from your query result object: $query
CodeIgniter comes with a full-featured and very fast abstracted database class that supports both traditional structures and Active Record patterns. The database functions offer clear, simple syntax.

Функции помощника запросов. $this->db->insert_id(). Вернет insert ID — номер последней добавленной записи. $this->db->affected_rows(). Вернет количество строк, задействованных в последнем «пишушем» запросе (insert, update и так далее). Примечание: В MySQL "DELETE FROM TABLE" вернет 0
Typically you'll use this in a foreach loop, like this: $query = $this->db->query("YOUR QUERY"); foreach ($query->result() as $row) { echo $row->title; echo $row->name; echo $row->body; }. The above function is an alias of result_object() . If you run queries that might not produce a result, you are encouraged to test the
This is a simplified version of the $this->db->query() function. It ONLY returns TRUE/FALSE on success or failure. It DOES NOT return a database result set, nor does it set the query timer, or compile bind data, or store your query for debugging. It simply lets you submit a query. Most users will rarely use this function.
Standard Query With Multiple Results (Object Version). $query = $this->db->query('SELECT name, title, email FROM my_table'); foreach ($query->result() as $row) { echo $row->title; echo $row->name; echo $row->email; } echo 'Total Results: ' . $query->num_rows();. The above result() function returns an array of objects.
By setting the second parameter to TRUE (boolean) the function will return the database object. When you connect this way, you will use your object name to issue commands rather than the syntax used throughout this guide. In other words, rather than issuing commands with: $this->db->query(); $this->db->result(); etc.

CodeIgniter does not require that each database table be its own class file. It instead provides a more simplified interface. Beyond simplicity, a major benefit to using the Active Record features is that it allows you to create database independent applications, since the query syntax is generated by each database adapter.
