You may have to add a SDSNLOAD library(that contains a member RXSUBCOM) to joblib in your JCL.

e.g.

//JOBLIB DD DSN=ssidPRD.ssid.SDSNLOAD,DISP=SHR

Database handling in php.

 

first open phpmyadmin and then create a new database named “test”( for the specific purpose of this example).

now create a table inside it named “counter” with a field “count” in it. ( integer,NULL,unsigned)

Now, create a file named server_auth.php in (root)/config folder. this folder you must remove all accessing permissions.

in server_auth.php

<?php 
$db_host = "localhost"; 
$db_user = "root"; 
$db_password = ""; 
$db_name = "test"; 
?>

 

create another file in your webroot named “ counter.php”

<?php 
     require($_SERVER["DOCUMENT_ROOT"]."/config/server_auth.php"); 
     $connection = @mysql_connect($db_host,$db_user,$db_password) or die("error connecting the database!"); 
     mysql_select_db($db_name, $connection); 
     $query = "SELECT * FROM counter"; 
     $result = mysql_query($query, $connection) or die(mysql_error()); 
     $views = mysql_result($result, 0, "count"); 
     $views++; 
     $query = "UPDATE counter SET count = $views"; 
     mysql_query($query, $connection) or die(mysql_error()); 
     echo "This page has been viewed ".$views. " times."; 
     ?>

ALL DONE! just open that counter.php in your browser and it will display a hit count!

Connecting to Database by writing code in VB.NET (Widout wizard)

Step 1. Add reference to system.data in your code

Click project->Add Reference

Select .Net tab

Select System.Data

Now click Ok.

Step 2. before Public Class Form1, write

Imports System.Data

Step 3. In Form load event

Dim Con As new OleDb.OleDbConnection

Step 4. Now write next

Con.Connectionstring=”PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=c:\mydatabase.mdb”

End Sub

Step 5. Open the connection to database with

Con.Open()

and display a msgbox to test the successful connection

msgbox(“the connection is opened”)

Step 6. Create new dataset and data adapter.

Dim ds As New DataSet

Dim da As OleDb.OleDbDataAdapter

Step 7. Pass new sql query to the data adapter

Dim sql As String

sql=”SELECT * FROM mydatabasetable1”

da=New OleDb.OleDbDataAdapter(sql,con)

This is how your Code should look like

Finally Fill the dataset with data.

da.Fill(ds,”mybase”)

This connects the database to dataset and fills it. Just that the data can’t be seen till now by anyone since it is not binded to any user viewable control.

txtFirstName.Text = ds.Tables("mydatabasetable").Rows(0).Item(1)

Private Sub Frmmain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim conn As New OleDb.OleDbConnection     conn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=pdjm.accdb;Persist Security Info=True;Jet OLEDB:Database Password=password123"     Dim ds As New DataSet     Dim da As New OleDb.OleDbDataAdapter     Dim sql As String     sql = "SELECT * FROM programmgmt"     da = New OleDb.OleDbDataAdapter(sql, conn)     da.Fill(ds, "mybase")     DataGridView1.DataSource = ds.Tables("MyBase")
