| | I have a couple of .frm files with no corresponding data or index files. Is it possible to recover the table structure (field names, types, sizes, rows,col, etc) from these files? The table type is innodb |

Here's a page from the MySQL manual that might help you solve your problem: http://dev.mysql.com/doc/mysql/en/backing-up.htmlI'm not too sure whether you can do it just on the basis of .frm files - do you have the .ibd files or ibdata file with them too ? If you have those the process becomes far easier... Read that page and see if it helps - and if it does, please come back here and make a post on what you did to solve your problem. That'll certainly be very helpful for all of us.. Thanks & Regards, m^e

.frm is a table created by mysql. you can fine in there a series of field but no guarantee the data itself. in order to rebuild the database using only .frm. i think you should do it manualy then. QUOTE MySQL will always create a `.frm' file to hold the table and column definitions. The table's index and data will be stored in one or more other files, depending on the table type. QUOTE MySQL stores its data dictionary information of tables in `.frm' files in database directories. But every InnoDB type table also has its own entry in InnoDB internal data dictionaries inside the tablespace. When MySQL drops a table or a database, it has to delete both a `.frm' file or files, and the corresponding entries inside the InnoDB data dictionary. This is the reason why you cannot move InnoDB tables between databases simply by moving the `.frm' files, and why DROP DATABASE did not work for InnoDB type tables in MySQL versions <= 3.23.43. further you should read at: mysqlOncom Beureum The Best Place in the City

First create a database to restore and create the tables with same name of XXX.frm files (with one field, only to create the .frm files); After, stop mysql service and replace the created .frm files with saved .frm files; Finally, start mysql service and see, the tables are replaced with old columns, but sure, without data.

Mysql Multiple Tables

It is good practice to use multiple tables to sort out big amounts of data. But once you do that it
becomes increasingly hard to cross reference the tables. Mysql has a little beautiful command
structure that they have added. You can select multiple tables within one sql query. Example of a
basic sql query CODE $sql = "SELECT * FROM table WHERE row=1"; If you noticed that I selected
all of the rows in the table. Normally you will try to not select the entire table from the database
unless you absolutely want all of the table. I would recommend against it; just gra...

The problem is to set file_priv of the database user to "Y" . This is done in the "user" table of
the maintanance database named "mysql". cPanel doesn't allow this. Via the cPanel you can only
