Database exception - what's nextπ

Generally speaking there are three reasons for this:
  • the database has been screwed up (quiet common)
  • an invalid SQL-query has been sent (occurs seldom in stable versions)
  • database versions does not match and should be updated
The first step is finding out more.

Database not available?π

If you even can't login any more. The database is not available. Use phpmysql or other tools to check your server.

Available but problems? - Get more detailsπ

If this is only a problem of a special page inside streber or is not reproducable this could be a SQL-problem. We need to find out more...
  1. log in as project manager or admin
  2. click on system info in the footer
  3. click on error.log : Parse
  4. go to the end of the list and look for the error-message like 20060616001505 ERROR: db/db.inc.php:38 - Datenbankfehler (hide)
  5. click on the date-number at the left for details
The details could look this this:

from errors.log

Especially interessting is the line starting with mysql_error =:

mysql_error = Can't open file: 'project.MYI'π

tells us, that the sql-table index-files are missing. To fix this use mysqladmin to repair sql-tables. In all cases this fixed the problem for me.

mysql_error = Incorrect key file for table 'project'; try to repair itπ

Other errorsπ

This might be a programming error. But before reporting this...
  1. check you version (at the bottom of the error-report) maybe there is a fix outside.
  2. search the tracker for a detail of the report (e.g. class_person.inc.php) to find similar posts.

Looks like you hard disk is full or something like this. If mysql cannot create files like "/tmp" this is probably not the best thing to happen.

guest:Same Problem

10 years ago -

I check the rights in the folder and all looks fine, what can you thing is it?

In advance regards

jtanen:Fatal Exception with $ in password

10 years ago

I hit a problem using a password for the database account that had a special character (in this case, a $).

Apparently, according to errors.log.php, the system parsed it incorrectly, declared the variable undefined, and tried to connect with NO password, and failed out. For now, I simply removed special characters from the password and it seems to work.

This was a duh moment on my side, of course, since it makes sense that the PHP would fail out on a $. Figured it was worth noting on here, though.
