1、插入一条记录
$data = array( 'title' => 'My title' , 'name' => 'My Name' , 'date' => 'My date' ); $this->db->insert('mytable', $data); // Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')
2、插入多条记录
$data = array( array( 'title' => 'My title' , 'name' => 'My Name' , 'date' => 'My date' ), array( 'title' => 'My title1' , 'name' => 'My Name1' , 'date' => 'My date1' ) ); $this->db->insert_batch('mytable', $data); // Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date'),('My title1', 'My name1', 'My date1')
用insert 和select 组合语句
例子如下:
数据插入Sales表:
INSERT INTO Sales(EmployeeID,ProductID,SupplierID,CustomerID,
OrderDate,UnitPrice,Total,Quantity,Discount)
SELECT e.EmployeeID, p.ProductID, s.SupplierID,
c.CustomerID, o.OrderDate, od.UnitPrice,
od.Quantity*od.UnitPrice*(1.0-od.Discount)Total,
Od.Quantity, od.Discount
from Orders o,[Order Details] od, Employees e,
Products p, Suppliers s, Customers c
where (o.OrderID = od.OrderID) and
(o.EmployeeID = e.EmployeeID) and
(o.CustomerID = c.CustomerID) and
(od.ProductId = p.ProductID) and
(p.SupplierID = s.SupplierID);
简单例子看下你就明白了
insert into news (type_id,userid) values ('5','8'),('6','10'),('11','55');
id如果是主键的话,插入的时候可以不用写
