I have an automated backup script that has been running daily for a
couple of years now. It has never given me trouble until the last two
days. For the last two days, I have been getting this message when
backing up my newest database:
/usr/bin/mysqldump: Got error: 1064: You have an error in your SQL
syntax. Check the manual that corresponds to your MySQL server version
for the right syntax to use near 'References READ /*!32311 LOCAL */'
at line 1 when using LOCK TABLES
This is the relevant portion of my backup script:
for ONE_DBNAME in `echo show databases | mysql -s -u $USERID -p$PASSWORD`
do
echo
echo "Backing up database" $ONE_DBNAME;
/usr/bin/mysqldump --opt --verbose -u${USERID} -p${PASSWORD}
${ONE_DBNAME} -r
${BACKUP_PATH}"/"${ONE_DBNAME}"."${BACKUP_TIMESTAMP}".sql"
I would look here. This is a dangerous expansion. A space or ';' in any
of these variables my generate unwanted commands.
Use quotes around the argument to -r.
Try.
/usr/bin/mysqldump --opt --verbose -u${USERID} -p${PASSWORD}
${ONE_DBNAME} -r "${BACKUP_PATH}/${ONE_DBNAME}.${BACKUP_TIMESTAMP}.sql"
or
/usr/bin/mysqldump --opt --verbose -u${USERID} -p${PASSWORD}
${ONE_DBNAME} > "${BACKUP_PATH}/${ONE_DBNAME}.${BACKUP_TIMESTAMP}.sql"
echo ">> Deleting these old backups for this database..."
/usr/bin/find ${BACKUP_PATH} -mtime
+$NUMBER_OF_DAILY_BACKUPS_TO_KEEP -name $ONE_DBNAME'*' -print;
#display old backups (if any)
/usr/bin/find ${BACKUP_PATH} -mtime
+$NUMBER_OF_DAILY_BACKUPS_TO_KEEP -name $ONE_DBNAME'*' -exec rm '{}'
';' #delete old backups (if any)
done
I'm at a loss to see why I'm getting this error for only one database
when the exact same logic is applied for each of my databases and
works fine for all the others.
I've tried doing the backup manually from the command line and found
that I got the same error when I tried to backup the Maximal database
that way; a manual backup of another database worked fine.
The only idea I have that seems vaguely plausible is that there is
something internally wrong with my database but I'm darned if I know
what the problem could be. When I do 'select *' against each of the
five small tables in this database, each returns exactly the right
data and there are no errors or warnings of any kind.
Can anyone suggest queries or commands that would reveal the status of
my database and its tables to make sure something is not messed up?
Any suggestions on resolving this problem would be greatly appreciated.
