HI All,  Ok first of all i am new to both mysql and to this forum so bare with the stupidy.

Background-  Our company use mysql 4.1 to host two databases for our bug tracking system "Eventum" One of the sites ( database) is working fine but the other has missing data (issues to be percise). When we try to enter issues into the system, we recieve an error stating that "There was an error creating you issue". My first thought is that there is a problem with one of the tables in the database, as all the others seem to work fine. We have tried to repair the database with the mysql administrator program, but the database type InnoDB does not support this.  We do however create backups of these databases using the mysqldump program.

Problem- As stated, the data is missing and we have backups of the databases. We recreated the whole system from the begining so that we would not have to test these procedures on the live server. So we have installed mysql 4.1 and the administrator tools, setup a replica schema with the same name as the origional. ( configured our eventum webpage )  granted access rights to a user account called restore,( now we have the default webpage which we can access and change ) We then changed some fields, made a backup and tried to restore the test database using the following command  "mysqldump.exe -u root -p databasename< c:\databasename_db_20050819.sql.  This did not work, so we deleted the schema, created a replica again, did not add any data this time and tried to restore using the same process. A sample of the output is below

-- MySQL dump 10.9
-- Host: localhost    Database: databasename
-- ------------------------------------------------------
-- Server version       4.1.13a-nt-max

/*!40101 SET NAMES utf8 */;


So we have tried to restore a database which had data in it and one which did not using a backup of the database which had data in it. if you understand.  And the biggest problem is that we have been unable to restore any of our test databases.. I have been working on this for four days as it is extremely important we get it running, so any help would be appreciated, Oh and i am awarding generously for anyone who can help resolve this, hopefully today.

I thought i should add a print out of the mysqldump that was generated when trying to restore the backup onto a replica blank database
