php CI框架插入一条或多条sql记录示例,cisql

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')

怎使用一条SQL语句,插入多条记录?

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);
 

PHP+mysql 一条信息里的同一字段怎插入多条记录?比如有多张图片地址

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
