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

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
