Hello everyone,

I updated my old bacula database from version 12 (Bacula version 5.0.0) 
to version 15 (Bacula version 7.4.2) which went more or less without 
errors (see below):

bacula@...:~/etc$ ./update_mysql_tables -u bacula -p

This script will update a Bacula MySQL database from version 12-14 to 15

Depending on the current version of your catalog,
you may have to run this script multiple times.

After that I tried to restore a file which gave me this error in bconsole:
20-Sep 13:13 backup-host-dir JobId 0: Fatal error: sql_create.c:86 
Create DB Job record INSERT INTO Job 
(Job,Name,Type,Level,JobStatus,SchedTime,JobTDate,ClientId,Comment)

'0000-00-00 00:00:00' for column 'StartTime' at row 1

How can I fix this?
Thanks you very much.
