AngularJS是完美的從數據庫中顯示數據。 只要確保數據是JSON格式。
獲取數據從一個PHP服務器運行MySQL
AngularJS例
<div ng-app="myApp" ng-controller="customersCtrl">
<table>
<tr
ng-repeat="x in names">
<td>{{ x.Name }}</td>
<td>{{ x.Country
}}</td>
</tr>
</table>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('customersCtrl',
function($scope, $http) {
$http.get("http://www.w3ii.com/angular/customers_mysql.php")
.then(function (response) {$scope.names = response.data.records;});
});

AngularJS例
<div ng-app="myApp" ng-controller="customersCtrl">
<table>
<tr
ng-repeat="x in names">
<td>{{ x.Name }}</td>
<td>{{ x.Country
}}</td>
</tr>
</table>
</div>

var app = angular.module('myApp', []);
app.controller('customersCtrl',
function($scope, $http) {
$http.get("http://www.w3ii.com/angular/customers_sql.aspx")
.then(function (response) {$scope.names = response.data.records;});
});

以下部分是用於獲取數據的SQL服務器代碼列表。
- 使用PHP和MySQL。 返回JSON。
- 使用PHP和MS Access。 返回JSON。
- 使用ASP.NET，VB，和MS Access。 返回JSON。
- 使用ASP.NET，剃須刀，和SQL精簡版。 返回JSON。
跨站點HTTP請求
從不同的服務器請求數據（而不是請求頁），被稱為跨站點的HTTP請求。
跨站點請求是常見的在網絡上。 許多網頁加載CSS，圖像和腳本來自不同的服務器。
在現代瀏覽器， 從腳本跨站點的HTTP請求被限制在同一站點出於安全原因。
下面的行，在我們的PHP的例子，已被添加到允許跨站點的訪問。
header("Access-Control-Allow-Origin: *");1.服務器代碼PHP和MySQL
<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type:
application/json; 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"] . '"}';
}
$outp ='{"records":['.$outp.']}';
$conn->close();
echo($outp);
?>
2.服務器代碼PHP和MS Access
<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type:
application/json; 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();
}
$outp ='{"records":['.$outp.']}';
$conn->close();
echo ($outp);
?>

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 & ","

next
outp

response.write(outp)
conn.close
