I've exported a database via SSH and I didn't add --routine command to export the routines.
Now I don't have any access to this database, and I have only one .sql file. is there any way to restore and find the routines through PHP code or database structures?
No, sorry, in this case I think you're out of luck. Looking at the database structure, you won't be able to figure out what a routine might have done. Likewise, looking at the PHP code is probably not going to help. If you know what the routines did (for instance, manipulate data on insert, maintenance by deleting some rows, or some such) you can work through recreating it, but that's basically reverse engineering it based on what breaks when you try to run your application.

I am trying to use mysqldump for backing up my database and restoring the same in remote a machine for disaster recovery purposes. As I havent used it before, I am having a basic question regarding the same.
Once I dumped and copied over the file,on the target machine, while importing, will it perform the import such a way that it creates new entities while updating any existing ones and deleting any entities deleted in the dump?
Basically, will it keep the target mysql in sync with the dump i.e. the same as on the source?
Thanks
Long story short(ish):
Mysqldump will create an SQL file that, when imported in an empty environment, makes a database that is the same as the one the dump was created from.
So no: it will not "sync" anything (e.g. delete files or update records). You can actually look at the file and you will see statements that first create a database, then create the tables and finally insert your data.
They way it works that you take an empty server, import the database and you have you origional situation back. Nothing less, but definitely nothing more as well.
I want to create a cronjob for making a backup (sql dump) from my database and e-mail it to me. Setting up the cronjob and stuff works great and I'm able to use parts of my zend application :)
Unfortunately I cannot use exec() or system() on my server so now I'm looking for a way to get the same result. I searched everywhere with all possible descriptions I could think of, but without any results.
So in short:
I want to backup my databaseup
Preferably in .sql format (like export in phpmyadmin)
Using the Zend framework (so I can use my already loaded
application.ini settings for the database)
I cannot use exec() or system()
I'm completely stuck so really anything would help! Thanks in advance!
The solution by David Walsh looks like what you want:
http://davidwalsh.name/backup-mysql-database-php
A php script that retrieves the tables in a database and saves the data in a .sql file.
If I were to want to create a PHP function that does the same thing as the Export tab in phpMyAdmin, how could I do it? I don't know if there is a MySQL function that does this or if phpMyAdmin just builds the export file (in SQL that is) manually. Without shell access. Just using PHP.
I tried the documentation for mysqldump, but that seemed to require using the shell. I'm not quite sure what that even is -- maybe my question is: how do you use shell?
My silly idea is to allow non-technical users to build a site on one server (say a localhost) using MySQL then export the site, database and all, to another server (eg. a remote server).
I think I'm pretty clear on the Import process.
You can check the phpMyAdmin source code (an advantage of open-source software). Check the export.php script and the supporting functions in the libraries/export/sql.php script file.
In summary, what phpMyAdmin does is:
get a list of the tables in the given database (SHOW TABLES FROM...),
get the create query for each table (SHOW CREATE TABLE...),
parse it and extract column definitions from it,
get all data (SELECT * FROM...)
build a query according to column data.
I've written similar code for my own apps (for backup purposes, when the GPL license of phpMyAdmin doesn't allow me to use it), however I use DESCRIBE to get column definitions. I think they rather parse the SHOW CREATE TABLE output because contains more information than DESCRIBE output.
This way to generate SQL sentences requires a bit of care to handle the escaping but it allows for some flexibility, as you can convert types, filter or sanitize data, etc. It is also a lot slower than using a tool like mysqldump and you should take care of not consuming all available memory (write soon, write often, don't keep everything in memory).
If you will implement a migration process (from server to server) maybe it would be easier to do it with some shell scripting and calling mysqldump directly, unless you will do everything with PHP.
I currently have a database in MySQL, which I'd like to import in MS Access.
Is it possible to do this while keeping all relationships intact (i.e. without exporting to .csv, or by using ODBC)?
I'm a noob in this area so any help is greatly appreciated.
Thanks.
You need to solve two different problems:
Creating an empty MS Access database with a structure that matches the MySQL database structure.
Extracting the data from MySQL and loading it into MS Access.
This is not easy because different SQL databases offer different structural features, different datatypes, and so on. The more complex your use of MySQL is the more likely you'll run into some show-stopper during the conversion (for instance, Access doesn't support triggers at all). Conversely if you're using MySQL as a simple data store you may find the conversion fairly easy.
To get an MS Access database with the same structure as your MySQL database, your best bet is to find a database definition / diagramming tool that offers reverse engineering and supports both MySQL and MS Access. Use it to reverse engineer your MySQL database into a database diagram, then change the underlying database to MS Access and use the tool to generate a database.
Check out Dezign For Databases which (on paper, anyway) offers the features you would need to do this.
To pump the data across, there are any number of tools. This kind of operation is generically referred to as ETL (Extract, Translate, Load).
Do you mean SQL Server? A good starting point might be to check out SQL Server Integration Services (SSIS), which can be used for transferring data around like that.
Google will also be helpful, check out the first result:
http://support.microsoft.com/kb/237980
By the way, you said ".sql" in your question: a .SQL file is a script file, which could do anything from create a database, insert data, drop table, delete data, or given the right permissions, call system procedures and reboot a machine, format a drive, send an email.. Just for ref, .SQL files aren't the storage format used by SQL Server.
While you can script your database's schema into script files via something like SQLyog, you will find that the syntax varies enough from database to database (MySQL to Access, in your case) that you can't directly apply the scripts.
With much effort a conversion script could be created by editing the script (perhaps automated with a program, depending on the resulting script size). I think you would be better served using ODBC to copy the tables (and data) and then extracting and re-applying the relationships from the generated script by hand. Time consuming, but also a one time operation I would hope.
When both systems are the same database, there are tools that can do the comparison and script generation (TOAD for MySQL and RedGate Compare for Microsoft SQL), but they don't do cross database work (at least not the ones I am aware of).
If you create a ODBC DSN, you can use TransferDatabase to import from your MySQL database. You can do it manually with the GET EXTERNAL DATA command (or whatever it is in A2007/A2010) and see how well it works. It won't get all data types exactly right, but you could do some massaging and likely get it closer to what will work best.
Is there some reason you can't just link to the MySQL tables and use them directly? That is, why do you need to import into Access at all?
Access: run query. Just make sure to adapt the SQL code since every RDMS has its own sintaxis (despite SQL being an ANSI standard).
Is there any program (preferably official) for Windows that can be used to manipulate MySQL data dumps?
For example, easily importing a MySQL text dump and create the database for all kinds of manipulations (you know, common data operations such as select, update, insert, delete, export into CSV, etc.) via a GUI interface. Much like what you can do with MS Excel and MS Access.
I know only phpMyAdmin which requires a local web server environment which might a little too much for what I need.
I thought http://dev.mysql.com/downloads/mysql/ was what I needed and installed to find out that it's not.
Any such tools exist? I ask this is actually because these MySQL dumps are for my users who know nothing about SQL or anything technical. This is for them, not me. After they downloaded the SQL I provided, they ask me: "How can I open it?"
I tried to provide them CSV, but CSV generated by this approach: http://www.kavoir.com/2010/11/mysql-export-table-to-csv-text-files-for-excel.html would contain stuff like \" if the original data contains ". When you open the CSV in Excel, \" are all over the place.

I used to use SQLyog at my last job. It's a pretty decent GUI tool for interacting with MySQL, either local or remote. It'll cost you $99 at the cheapest, but you can try it for 30 days. If you like it and it makes life easier, it could be worth the $99, as well.
Running a local server is actually pretty easy. I use xampp which was really easy to install and came set up and ready to use phpMyAdmin. It's also really easy to shut the whole server (or just parts of it) down when it's not in use to conserve system resources.
