SQL

在前面章节中的代码也可以用于读取数据库中的数据。

使用 PHP 从 MySQL 中获取数据

<div ng-app="" ng-controller="customersController">

<table>
  <tr ng-repeat="x in names">
    <td>{{ x.Name }}</td>
    <td>{{ x.Country }}</td>
  </tr>
</table>

</div>

<script>
function customersController($scope,$http) {
    var site = "http://www.w3cschool.cn";
    var page = "/statics/demosource/Customers_SQL.php";
    $http.get(site + page)
    .success(function(response) {$scope.names = response;});
}
</script>

ASP.NET 中执行 SQL 获取数据

<div ng-app="" ng-controller="customersController">

<table>
  <tr ng-repeat="x in names">
    <td>{{ x.Name }}</td>
    <td>{{ x.Country }}</td>
  </tr>
</table>

</div>

<script>
function customersController($scope,$http) {
    var site = "http://www.w3cschool.cn";
    var page = "/try/angularjs/data/Customers_SQL.aspx";
    $http.get(site + page)
    .success(function(response) {$scope.names = response;});
}
</script>

PHP 读取 MySQL 数据代码

<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type: text/html; charset=UTF-8");

$conn = new mysqli("myServer", "myUser", "myPassword", "Northwind");

$result = $conn->query("SELECT CompanyName, City, Country FROM Customers");

$outp "[";
while($rs = $result->fetch_array(MYSQLI_ASSOC)) {
    if ($outp != "[") {$outp .= ",";}
    $outp .= '{"Name":"'  . $rs["CompanyName"] . '",';
    $outp .= '"City":"'   . $rs["City"]        . '",';
    $outp .= '"Country":"'. $rs["Country"]     . '"}';
}
$outp .="]";

$conn->close();

echo($outp);
?>

PHP 读取 MS Access 代码

<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type: text/html; charset=ISO-8859-1");

$conn = new COM("ADODB.Connection");
$conn->open("PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=Northwind.mdb");

$rs = $conn->execute("SELECT CompanyName, City, Country FROM Customers");

$outp = "[";
while (!$rs->EOF) {
    if ($outp != "[") {$outp .= ",";}
    $outp .= '{"Name":"'  . $rs["CompanyName"] . '",';
    $outp .= '"City":"'   . $rs["City"]        . '",';
    $outp .= '"Country":"'. $rs["Country"]     . '"}';
    $rs->MoveNext();
}
$outp .= "]";

$conn->close();

echo ($outp);
?>

服务端 ASP.NET, VB 和 MS Access 代码

<%@ Import Namespace="System.IO"%>
<%@ Import Namespace="System.Data"%>
<%@ Import Namespace="System.Data.OleDb"%>
<%
Response.AppendHeader("Access-Control-Allow-Origin", "*")
Dim conn As OleDbConnection
Dim objAdapter As OleDbDataAdapter
Dim objTable As DataTable
Dim objRow As DataRow
Dim objDataSet As New DataSet()
Dim outp
Dim c
conn = New OledbConnection("Provider=Microsoft.Jet.OLEDB.4.0;data source=Northwind.mdb")
objAdapter = New OledbDataAdapter("SELECT CompanyName, City, Country FROM Customers", conn)
objAdapter.Fill(objDataSet, "myTable")
objTable=objDataSet.Tables("myTable")

outp = "["
c = chr(34)
for each x in objTable.Rows
if outp <> "[" then outp = outp & ","
outp = outp & "{" & c & "Name"    & c & ":" & c & x("CompanyName") & c & ","
outp = outp &       c & "City"    & c & ":" & c & x("City")        & c & ","
outp = outp &       c & "Country" & c & ":" & c & x("Country")     & c & "}"
next

outp = outp & "]"
response.write(outp)
conn.close
%>

服务端 ASP.NET, VB Razor 和 SQL Lite 代码

@{
Response.AppendHeader("Access-Control-Allow-Origin", "*")
var db = Database.Open("Northwind");
var query = db.Query("SELECT CompanyName, City, Country FROM Customers");
var outp ="["
}
@foreach(var row in query)
{
if outp <> "[" then outp = outp + ","
outp = outp + "{" + c + "Name"    + c + ":" + c + @row.CompanyName + c + ","
outp = outp +       c + "City"    + c + ":" + c + @row.City        + c + ","
outp = outp +       c + "Country" + c + ":" + c + @row.Country     + c + "}"
}
outp = outp + "]"
@outp
