I have gone through a data migration and previous data is stored in MS-Access DB so the database has file attachment field,, here is the problem that i want to extract attached file or image to file directory.
OR if its possible for conversion to MySQL database.
Any Solution ???

I have found the solution to load xml file data to mysql db table Here
My question is how I can load remote location xml file and dump it to mysql database table.
If you have any idea or have done something like this please help to find the solution.
Thank you
LOAD XML statement does not support retrieving files from a remote location. The file has to be either on the server, or on the client (LOCAL - if enabled in configuration). You need to write a script that saves the file either to the server or to the client from the remote location.
If you manage to map a remote shared directory to the local fileszstem, then you can import data that way.
So we got an old program, from about 2006-2007.
that program uses a very large database.
the database is separated into 3 files:
(file extensions were renamed.)
1 of 1,061,758,976 bytes
1 of 1,062,225,920 bytes
and 1 of 423,604,224 bytes
(total about 2.4 GB).
what we want to do is get rid of that program and write our own, using the same database.
the only problem is that we don't know anything about those files. Rumors says that those files are access files - but we don't know how to confirm that.
also, the goal is to put this whole database into a mySQL database - which is another challenge.
Summarizing:

Converting to mySQL.
Any help will be much appreciated.
EDIT: File header:
Determine database type
The screenshot cited in the comments to the question indicate that the file is an Access .mdb database file. Access database files contain the following 15-character strings starting at byte offset 4:
Standard Jet DB ...for an .mdb file
Standard ACE DB ...for an .accdb file
Converting to mySQL.
The most straightforward way would be to install the MySQL ODBC driver, create an ODBC DSN to the target MySQL server, then open the .mdb file in Access and export the tables to MySQL via ODBC.

edit re: "You do not have the necessary permissions..." error
It appears that the database file was encrypted using the "User-Level Security" feature that Access offered for older .mdb files. If so, then to open the file you will need:
The associated Workgroup Security file (often called "Security.mdw", but may have a different name)
Login credentials (username and password) for a user that was created in that Workgroup file.
If you have both of those prerequisites then you should be able to open the file using something like the following from the command-line:
MSACCESS.EXE "C:\Users\Public\uls\db1.mdb" /WRKGRP "C:\Users\Public\uls\Security.mdw"
Search around to see if you can find the associated .mdw file (possibly renamed). Note that if if you find a file named System.mdw under %SystemRoot% or %APPDATA% it may not be the one you need. (Access creates a default Workgroup file for normal unprotected databases.) The file you are looking for should have a similar 15-character string starting at byte offset 4:
Jet System DB ...for an .mdw file (note that there are two trailing spaces to make 15 characters)
Huge mysql noob. Sorry in advance if this is dumb but I have searched around before posting.
I use mysqlimport on a local file to a mysql database that's running on my computer. If I delete the original file that was imported, can I still access the data? If so, where is the data being stored? On some Oracle server?
If it's stored locally, is it stored in a compressed version that takes up less space on my harddrive?
Thanks,

if you import a file to a database, it is going to store an instance of that data in the database, so yes, you should still be able to access the data, but why would you want to delete it?
It is being stored in a pool of database files in mySQL, they are referenced when you start mysql...yes the imported doc, is just a .dat file in most cases, as your database file.
When you import the data it is stored in database files on your local machine, using the mysql client program or something like phpmyadmin you should be able to view your imported data.
It's no longer stored in the same format as it was when you first imported it.
you can use something like mysqldump to get the data back out.

I deleted my database and customer service sent me back a .dat file but their instructions what to do with it were bad.
They said to put the (db_backup.dat) file in mysql/data folder and then do an export to sql to restore data. Can anyone help out here how to do this the file is not a text file with sql commands in it just lots of things that are not readable.
I'm assuming the .dat file is a text file.
mysql -u root -p password < db_backup.dat
Looks like they could've sent you bare data file, which you should put into mysql folder and restart mysql server.
In case they sent you bare DB file, you should ask customer service which format is that. It could be a MyISAM or InnoDB file. In case they tell you format you should crate a new database of that format titled db_backup, then find where you mySQL instance keep files, stop server, put the file you get from CS into that folder, replacing existing one and start server again.
Finally, can you post few first lines of the file or screenshot from Notepad++ ?
P.S. All above are guesses until you post head of the file or which format it is.
Hi I need to copy data from a csv file into a mysql table.Copy of data has to be remotely.My csv file is not present on the db server.Any idea how to do it.
I can do locally file copy from csv but not from different machine.
thanks
you have many options. If you have phpMyAdmin or other sql manager - it is easier variant. Else you should copy the file locally and use mysql shell tools to import the data.
Take a look at LOAD DATA . By using the LOCAL option, you specify that it's a local file and not a file located on the db server. The FIELDS TERMINATD BY and other options lets you adjust to the format of your .csv file
