AngularJS SQL

The code in the previous chapters can also be used to read data from a database.

Use PHP to get data from MySQL

AngularJS Examples

<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) {
    $http.get("https://www.example.com/try/angularjs/data/Customers_MySQL.php")
    .success(function (response) {$scope.names = response.records;});
});
</script>

Execute SQL in ASP.NET to get data

AngularJS Examples

<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) {
    $http.get("https://www.example.com/try/angularjs/data/Customers_SQL.aspx")
    .success(function (response) {$scope.names = response.records;});
});
</script>

Server-side code

The following lists several types of server-side code:

  1. Use PHP and MySQL. Return JSON.
  2. Use PHP and MS Access. Return JSON.
  3. Use ASP.NET, VB, and MS Access. Return JSON.
  4. Use ASP.NET, Razor, and SQL Lite. Return JSON.

Cross-domain HTTP requests

If you need to get data from a different server (different domain), you need to use cross-domain HTTP requests.

Cross-domain requests are very common on web pages. Many web pages load CSS, images, JS scripts, etc. from different servers.

In modern browsers, for data security, all requests are strictly restricted to the same domain. If you need to call data from different sites, you need to use cross-domain solutions.

The following PHP code runs on the website used for cross-domain access.

header("Access-Control-Allow-Origin: *");

For more cross-domain access solutions, see:PHP Ajax cross-domain problem best solutions。

1. PHP and MySQL code example

<?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. PHP and MS Access code example

<?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. ASP.NET, VB and MS Access code example

<%@ 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. ASP.NET, VB Razor and SQL Lite code example

@{
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 <> "" 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 ="{" + c + "records" + c + ":[" + outp + "]}"
@outp
