AngularJS SQL
AngularJS sangat cocok untuk menampilkan data dari Database. Pastikan saja datanya dalam format JSON.
Mengambil Data Dari Server PHP yang Menjalankan MySQL
Contoh AngularJS
<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) {
$http.get("customers_mysql.php")
.then(function (response) {$scope.names = response.data.records;});
});
</script>
Mengambil Data Dari Server ASP.NET yang Menjalankan SQL
Contoh AngularJS
<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) {
$http.get("customers_sql.aspx")
.then(function (response) {$scope.names = response.data.records;});
});
</script>
Contoh Kode Server
Bagian berikut adalah daftar kode server yang digunakan untuk mengambil data SQL.
- Menggunakan PHP dan MySQL. Mengembalikan JSON.
- Menggunakan PHP dan MS Access. Mengembalikan JSON.
- Menggunakan ASP.NET, VB, dan MS Access. Mengembalikan JSON.
- Menggunakan ASP.NET, Razor, dan SQL Lite. Mengembalikan JSON.
Permintaan HTTP Lintas Situs
Permintaan data dari server yang berbeda (selain halaman yang meminta), disebut permintaan HTTP lintas situs .
Permintaan lintas situs adalah hal biasa di web. Banyak halaman memuat CSS, gambar, dan skrip dari server yang berbeda.
Di browser modern, permintaan HTTP lintas situs dari skrip dibatasi ke situs yang sama karena alasan keamanan.
Baris berikut, dalam contoh PHP kami, telah ditambahkan untuk memungkinkan akses lintas situs.
header("Access-Control-Allow-Origin: *");
1. Kode Server PHP dan 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. Kode Server PHP dan 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);
?>
3. Kode Server ASP.NET, VB dan MS Access
<%@ Import Namespace="System.IO"%>
<%@ Import Namespace="System.Data"%>
<%@ Import Namespace="System.Data.OleDb"%>
<%
Response.AppendHeader("Access-Control-Allow-Origin", "*")
Response.AppendHeader("Content-type", "application/json")
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 ="{" & c & "records" & c & ":[" & outp & "]}"
response.write(outp)
conn.close
%>
4. Kode Server ASP.NET, Razor C# dan SQL Lite
@{
Response.AppendHeader("Access-Control-Allow-Origin", "*")
Response.AppendHeader("Content-type", "application/json")
var db = Database.Open("Northwind");
var query = db.Query("SELECT CompanyName, City, Country FROM Customers");
var outp =""
var c = chr(34)
}
@foreach(var row in query){
if (outp != "") {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 ="{" + c + "records" + c + ":[" + outp + "]}"
@outp
