如何在Code igniter中执行select查询[关闭]

Question

I just started using CodeIgniter and would like to execute the query below. But I don't know how to write this using CodeIgniter. This query successfully executes in phpMyAdmin.

 SELECT sales.sales_id
       , sales.sales_date
       , sold_item.item_id
       , sold_item.quantity
       , general_sales.cust_id
 FROM sales 
        JOIN general_sales ON sales.sales_id =general_sales.general_sales_id
        JOIN sold_item ON general_sales.general_sales_id= sold_item.sales_id
 WHERE sales_date= ?

Answer 1

Use this code where $date is date you are looking for

$query = $this->db
->select("sales.sales_id,sales.sales_date,sold_item.item_id,sold_item.quantity,general_sales.cust_id")
->from("sales")
->join("general_sales", "sales.sales_id =general_sales.general_sales_id")
->join("sold_items", "general_sales.general_sales_id= sold_item.sales_id")
->where("sales_date", $date)
->get();

and then you can work with results with for example $query->result_array()
