PHPAutomatedDbBackup

Credits: David Walsh for his db backup script. http://davidwalsh.name/backup-mysql-database-php

I implemented a script that can be run via cron, and can schedule different time for backing up diffrent databases.
It reads details of databases scheduled to back up at the toime of execution and create backup
You can schedule the backup of different databases at different time.
The time precision check for minutes only

How to setu-up

Move the code to your server under a directory say "DB_Backup"
Create a database, and a table with this structure

CREATE TABLE IF NOT EXISTS `table_credentials` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` varchar(255) NOT NULL,
  `host` varchar(255) NOT NULL DEFAULT 'localhost',
  `db_name` varchar(255) NOT NULL,
  `user_name` varchar(255) NOT NULL,
  `password` varchar(255) NOT NULL,
  `scheduled_execution_time` time NOT NULL,
  `created_date_time` datetime NOT NULL,
  `updated_date_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `execution_status` enum('0','1','2','3') NOT NULL DEFAULT '0',
  `last_execution_date` datetime NOT NULL,
  `created_ip` varchar(50) NOT NULL,
  `updated_ip` varchar(50) NOT NULL,
  `is_active` enum('0','1') NOT NULL DEFAULT '1',
  `is_mannual` enum('0','1') NOT NULL DEFAULT '1',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

Now update config.php with your db username, password etc.

Add the credentials of databases you want to backup
If you want to backup 5 databases at 12:00 am and 5 other at 1:00 am the make the value of scheduled_execution_time '12:00:00' for the first 5 databases and '1:00:00' for the next 5 databases.

Now schedule the cron to to execute

ROOT_DIRECTORY/DB_Backup/backup_db.php at 12:00 and 1:00

Thats it.

Any suggestion, updates and modification is welcome

Mysql tips and tricks

User records table: How to get all ids of peoples who have matching year and month only

First thing you have to achieve is to

"get all date and month of 'dob' column"

This can be achieved by grouping rows based on date_month extracted using the format construct.

SELECT 
DATE_FORMAT(dob, '%m-%d') AS date_month 
FROM bday 
GROUP BY DATE_FORMAT(dob, '%m-%d');

As per your question, Next is

"peoples who have matching year and month only"

ie, group the above results with condition having more than one row. This can be achieved by adding the condition "HAVING count(id) > 1"

Now the query becomes

SELECT 
DATE_FORMAT(dob, '%m-%d') AS date_month 
FROM bday 
GROUP BY DATE_FORMAT(dob, '%m-%d') 
HAVING count(id) >1);

This query returns all date_month where more than one person's dob falls.

Now your ultimate aim is to get

" id of those peoples who have matching year and month only "

This can be achieved by wrapping this results in a sub query. ie, you have to fetch all ids with date and month falls in the set of results extracted using the previous query

SELECT 
id, DATE_FORMAT(dob, '%m-%d') AS date_month
FROM bday
WHERE 
DATE_FORMAT(dob, '%m-%d') IN 
(
    SELECT 
    DATE_FORMAT(dob, '%m-%d') AS date_month 
    FROM bday 
    GROUP BY DATE_FORMAT(dob, '%m-%d') 
    HAVING count(id) >1) ;
)

Reference: http://stackoverflow.com/a/10485817/345721

SET @rownumber = 0;
update mytable set Moneyorder = (@rownumber:=@rownumber+1)
order by MoneyOrder asc

or to do it in a single query you can try

update mytable cross join (select @rownumber := 0) r set Moneyorder = (@rownumber := @rownumber + 1) order by MoneyOrder asc

Tips and tricks of GIT

Removing Files you have added files to Git that you want it to track no longer.

Scenario: You added a file to Git accidentally or you may want to remove a file from current push
You cannot run git rm because you want to keep a copy of the file(git rm command will delete the file from file system)


 Solution: To tell Git to stop tracking a file, but still keep it on your local system, run the following command

git rm --cached [file_name]

GIT - Ignore changes in a file

--Assume file to be unchanged
git update-index --assume-unchanged path/to/file.txt

GIT - Add all files that are tracked and has change

Scenario: I have modified large set of files and added new files as well and I want to stage only the tracked files. In such situations, I can use this command

git add -u

Using Branches

1. git branch

Usage: List all of the branches in your repository.

2. git branch <new_branch>

Usage: Create a new branch called <new_branch>. This does not check out the new branch.

3. git branch -d <branch>

Usage: Delete the specified branch. This is a “safe” operation since Git prevents you from deleting the branch if it has unmerged changes.

4. git branch -D <branch>

Usage: Force delete the specified branch. Use this command only if you want to permanantly discard all unmerged changes

5. git branch -m <new_branch>

Usage: Rename the current branch to <new_branch>.

6. git clone git@yourrepositry.com:projectidentifier new-folder-name

Usage: Clone git repository to a folder with different name.

7. git reset --hard

Usage: Resets your index and reverts the tracked files back to state as they are in HEAD.

8. git clean -f -d

Usage: Cleans untracked files.

9. git clean -f -d -x

Usage: Remove your .gitignored files and get back to a pristine state

10. git log branch_name..origin/branch_name

Usage: Find difference between my local branch and remote branch

GIT - Stash

11. git stash

Usage: Stash files for future reference

12. git stash show

Usage: List stashed files

13. git stash show -p

Usage: Show changes in stashed files

14. git stash save -p "message"

Usage: Lets you choose changes to be stashed, you can stash part of changes in a file as well
