Fetch values in OOPS PHP

Blogs , , , , , , , , , , , , , 0 Comment

Fetch_values.php i have create a fetching value page so here i have to include config.php for connection page must be in that folder so we can fetch data from database.

Suppose if we stored config.php file so we need to add config page for receiving data

require(“include/ config.php “); also can use require_once(“include/ config.php “);

(Difference between Include ,Include_once & require ,require_once)

include – include or include_once produce E- Warning and scripts will continue ,

require or require_once – Produce a fatal error E – Compile Error and stop the scripts 

<?php 
 require_once('include/config.php');
 class FetchValues
 {

private $id; 
private $db; 
private $setLimit; 
private $pageLimit; 
private $banner_id;

 function __construct() {    

 $this->db = new Database(); }

public function getAboutUsById($id)
 {    
 $this->id = $id;     
$query = "SELECT * FROM testabout WHERE about_id = '$id' AND status=0 LIMIT 1";    
 $exe_query = $this->db->execute($query);     
$result = $this->db->getResult($exe_query);    
 return $result; 
}

public function getAboutUsData()
 {    
 $query = "SELECT * FROM testabout";     
$exe_query = $this->db->execute($query);    
 $results = $this->db->getResults($exe_query);    
 return $results; 
}

public function getWhatsIncludes()
 {     
$query = "SELECT * FROM includes WHERE status=0 ORDER BY include_id DESC";     $exe_query = $this->db->execute($query);    
 $results = $this->db->getResults($exe_query);    
 return $results; 
  }

CREATE TABLESPSCE

Blogs , , , , , , , , , , , , , , , , , 2 Comments

A tablespace is a storage location where the actual data underlying database objects can be kept. It provides a layer of abstraction between physical and logical data, and serves to allocate storage for all DBMS managed segments.

A tablespace is a logical group of data files in a database. A database typically contains at least one tablespace, and usually two or more. Within the database, the tablespace plays a role similar to that of a folder on the hard drive of a computer.

Datafile : Describe all database files , Datafiles are physical files stored on your disk created by Oracle database and has .dbf extension.

CREATE DBA DATA FILES TABLESPACE

We have to find the file location in DBA DATA FILES

Now here describing dba data files

SQL> desc dba_data_files;

We can use one of them

SQL> describe dba_data_files;

Here Selection Specific columns

DBA DATA FILES Selecting the  FILE_NAME

SQL> SELECT FILE_NAME FROM dba_data_files;

TABLESPACENAME describe including with Created files name users

If we will create new TABLESPACENAME it will also reflect in File Name.

SQL> SELECT FILE_NAME, TABLESPACE_NAME FROM dba_data_files;

Now I am going to change the Bytes into MB

Now you can see here I have converted BYTES in MB.

SQL> select FILE_NAME,TABLESPACE_NAME,BYTES/1024 as size_in_mb from dba_data_files;

Now converting BYTES size in GB

SQL> select FILE_NAME,TABLESPACE_NAME,BYTES/1024/1024/1024 as size_in_gb from dba_data_files;

Now started to create tablespace

We need to know in which directory tablespace file used to create

So here

SQL> Select FILE_NAME from dba_data_files;

So We found the tablespace directory .

Whenever we are creating tablespace we used to create tablespace in oracle default directory including with path in string format.

(extention of tablespace .dbf)

SQL> create tablespace querypanel26 datafile ‘/u01/app/oracle/oradata/q

ueryp/querypanel26.dbf’ size 400m autoextend on;

Now you can see one tablespace is included in tablespace directory.

DATAFILE : before add datafile in tablespace we must have to aware about data files create location . How do we find datafiles storage location

SQL> desc dba_data_files;

Now we are looking for File Name and tablespace

so we promote a select query

SQL> select FILE_NAME,TABLESPACE_NAME from dba_data_files;

Here ADD datafile

SQL> alter tablespace q04 add datafile ‘/u01/app/oracle/oradata/queryp/q04datafile.dbf’ size 5m autoextend on;

we can also assign unlimited tablespace

sql>grant unlimited tablespace to q02;

Lock & Unlock Users

How do lock users account and unlock account.

SQL> alter user query1 account lock;

Now we need to find the user account status.

SQL> select USERNAME,ACCOUNT_STATUS from dba_users;

Here you can see query1 user account is locked

Now need to unlock user account

SQL> alter user query1 account unlock;

Now here user is unblock

SQL> select USERNAME,ACCOUNT_STATUS from dba_users;

User password Expire

We could not login via old password

SQL> alter user query1 password expire;

Whenever we will used to expire password need to set a new password during the user login

User session

Note: When it is in read/write mode, the status will simply say “ONLINE”

Rename Tablespace

SQL> alter tablespace Q05 OFFLINE normal;

SQL> alter tablespace Q05 RENAME TO QP05;

Assign Tablespace while creation of new users

here i have mention specific tablespace to user

SQL> create user q3 identified by q3 default tablespace sept_q3;

we can check here default tablespace to user

Q3 User default tablespace is sept_q3 because i used to mention this particular user carry this tablespace

we can also tablespace while we create table

easy to assign tablespace also like this

SQL> create table q3_insert_1(q_id INT NOT NULL PRIMARY KEY,NAME VARCHAR(20)) tablespace sept_q3;

A temporary tablespace, as its name implied, stores the temporary data that only exists during the database session.

Oracle uses temporary tablespaces to improve the concurrency of multiple sort operations which do not fit in memory. On top of this, Oracle stores temporary tables, temporary indexes, temporary B-trees, and temporary LOBs in temporary tablespaces.

By defeault, Oracle creates a single temporary tablespace named TEMP for each new Oracle Database installation. This TEMP tablespace can be shared by multiple users.

Now here we are going to create temporary tablespace

SQL> CREATE TEMPORARY TABLESPACE q3temp_1 TEMPFILE ‘/u02/app/oracle/oradata/sept/q3temp_1.dbf’ SIZE 40m;

now we can check temporary tablespace in dba_temp_files

we can see temporary tablespace is created

To install Oracle Database Client perform the following steps:

Oracle DBA Installation Guide

How to install linux using oracle virtualbox

Steps:

Oracle VM VirtualBox is a free and open-source hosted hypervisor for x86 virtualization, developed by Oracle Corporation.

First Download Virtual box (Virtual Machine )

(Example :  VirtualBox-6.0.10-132072-Win )

 Custom Setup Just Next

Network Interface just next to it

click on Install and Next to finish

Installation Completed Oracle Virtual Box

Virtual Box after installation Display

Go to machine tab click over there add machine and select the Driver where you wanted to install Linux

add location specified where you wanted to install Linux and in Drop down menu Select Operating system and version

Click to next

Allocate RAM Space in your system & Allocate Hard disk (HDD) Space

Select Virtual Box Disk Image

Storage Section we can Assign Physical Hard Disk Space( we can select any of one now I am selected Dynamically

After the Following Steps User created in Virtual Box

Right click on user select Setting Tab

Click on Add button

After that click on empty and select disk option ,select Downloaded Linux Version file and click okay

Right click on user normal start tab after that booting just click to next

After that click on web server

We have to wait until the installation Will completed

Completed Installation

We need to follow the steps

During the Oracle step we will also used to create User

And password

Now we need to create login username : root : and password :   12345 if we will skip the user we can also login via root

Now Oracle Linux is ready to use after valid username & password & Window will be appear like this

now go to Linux Application tab and Click on Terminal tab

and Terminal Window we will used to write ifconfig cmd

Now we need to download some of Specific Software Download PuTTY – a free SSH and telnet client PuTTY for Linux

PuTTY is a free and open-source terminal emulator, serial console and network file transfer application. 

PuTTy Configuration we need to Connect PuTTy Via IP Address

connected via puTTy we will get New Black Window login as : username( root)

puTTy Password what we have used during Linux Installation

Now we need to Specific Software for Download
