I am developing my first php-MySQL system, but have a minimum of database experience. I have successfully created a schema with aproximately 10 tables, and the testings have so far worked fine.
My problems started when i created a dump of the database, as copy for my laptop, so I could continue to test new web pages and new queries even when I am not at home, and still use a localhosted database.
I have successfully imported the dump, and created the schema in my workbench, and it is visible from the command-line prompt "show databases".
However, both my web application, and the command-line prompts are unable to locate the underlying tables. THe problem is at least not directly in my php-code, as it works perfectly on another computer, with another, but assumably identical localhosted database. I have researched the matter online for what feels like a decade, but without any relevant results.
Command-line prompts are able to find tables from every other schema, like the sakila examples. I have tried to compare the two's settings, but they all seem to be identical, for instance they are both InnoDB.
I realise that I am not giving enough information for a direct solution here, but I would greatly appreciate if anyone could hguide me to finding the right questions to ask, so I can solve this matter, and get on with my php-learning.
(SOLVED)
I discovered that the list of open tables had references to an additional Schema. I thereafter realised that I had installed the XAMPP bundle server before I installed MySQL Workbench. In other words, i already had an existing database, with all of the regular examples included in another instance, which were running on port 3306. It also happpened to have an identical, but empty scheme, of the name that I tried to access.
My newly added SQL installation was ported to 3307, and so I am now able to access it. THis issue was just one of several issues I have been able to work around, but they have all been caused by the same mistake. Thanks everyone for trying to help.

I am trying to start a php website and its database is missing currently i am stuck t this error can anyone help me what it is if it is keys how to find .
Please suggest me how to get keys and database details from php files.
You appear to be trying to install a pre-built application on an Apache webserver. One would normally consult the documentation for setting up the application to find where database passwords are kept. From the error message displayed, it looks like connecting to the database is not the issue as it is complaining about a specific column. It may be a bug in the application. You could maybe try downloading the most recent version of the application if the one you have is not the most recent. Other than that, you may need to contact the developer and report the bug. De-bugging it yourself could be very time-consuming. You could try a different application in that case, maybe.
I have a moodle database which I exported a few months ago before our server went down. Now I want to generate reports from my old database, I have tried to import to new moodle site but moodledata folder is missing. So now I'm looking for another way to generate reports from my database. I have tried to make Msql queries but I think that would take a lot of time for now. I need help if there is any tool around which I can use or any API which I can use to generate reports from my database. I have tried to use Seal Report to tackle this issue but I have found that there is a lot of manual work to be done, I don't means this tool can't do that but I'm just looking if there is any other tool which can simplify my task.
NB: I know some will say this is not a programming question, Please feel free to suggest any best way to query using any language.
You should be able to set up a local copy of a Moodle site with a copy of the database and with a blank Moodle data folder (I've done this regularly in order to investigate issues on a customer's site).
Once you've done that, you will have access to any reporting tools you would normally have inside Moodle.
You may find it easiest to set up a fresh install of Moodle, pointed at a blank database, then, once the install is finished, edit the config.php file to point at the restored copy of the original site. You may have to purge caches (php admin/cli/purge_caches.php) and you may have to reset the admin password (php admin/cli/reset_password.php). It is also wise to turn off email (edit config.php and add $CFG->noemailever = true; ).
I recently had to format my computer but I made sure I backed-up all my files before. I am developing lots of local sites using Xamp on my Windows 7 machine.
When I tried to move the files back onto the same drive (c:) and then looked at PHPMYADMIN the tables where there but all empty.
I have all the xamp files including the .frm files but the phpmyadmin shows the DB's but they are all empty i.e showing no tables inside.
Really hope someone can help as I have potentially lost a LOT of work. Thanks in advance.
When you said "I made sure I backed up all my files" -- which files are you talking about? There are the MySQL data files, the XAMPP program files, and then any exported .sql files you may have backed up. The best way to create a backup is to "dump" an SQL file from the database ("Export" from within phpMyAdmin, though I generally use the mysqldump command-line tool). If you didn't do that but still have the MySQL data directory, the links provided by Peter Michael will guide you (although relying on the MySQL data directory isn't generally a good backup means, because of various inconsistencies or loss that can occur with your data; whether it works at all also depends on your table type). I don't know where those data files are stored when using XAMPP and a cursory Google search gives a couple of different options, so good luck.
I was learning some web design about 18+ months ago and got caught up on some other things and had to stop for a while. I'm getting back into web design again. I used xampp back then and using xampp now also. I found my old xampp zip of the entire folder. I extracted it thinking I might get lucky and get my databases back from mysql. I go into the xampp\mysql\data and I copied all the folders with the databases I wanted to put into the new mysql. I loaded up phpmyadmin and the databases are there but they are all empty.
The main database I want to save has these files inside of it...
db.opt
pcms_categories.frm
pcms_meta.frm
pcms_posts.frm
pcms_users.frm
so I see the table files there but mysql isn't loading them. I assume maybe it's an older version and it won't read these files because they are obsolete. I'm not sure. After transferring the files I stopped mysql and reloaded it so just wanted to mention that.
It's been so long ago that it doesn't exactly matter if I can recover this data. I was working on a blog though would be cool to get that back and finish what I started.
try to dump it to .sql perhaps?
in other word, export/import.
First, I'd check for permission issues. MySQL usually requires special permissions on its datafiles. Check to see if MySQL has created its own user/group. Next, I'd try to find out what version of MySQL you previously had, create an installation of said version, and use it to dump the datafiles to SQL.
I have a small mySQL database and a few simple php based webpages that query the database, generate html tables and present them in the browser. The database is no longer being updated. So, searching and viewing subsets of the data is all that is required.
Some users are interested in distributing the searchable database on a cd or usb memory stick. SQLite seems to offer the answer, but I don't understand what is needed to make this work. What will be required to make a web browser based "app" work from a memory stick in the absence of a server like xampp?
XAMPP Lite from http://portableapps.com/apps/development/xampp
What you want is called a "standalone server". This is very common in almost every other modern language except PHP, for some reason. Googling "standalone php server" reveals several options:
QuickPHP
Nanoweb
Server2Go
