When running mysql from the command line (Putty terminal) and trying to do
some updates the updates fail. First the query I am running -
mysql> update warranty_temp, warranty_old set
warranty_old.OwnerName=warranty_temp.OwnerName where
warranty_old.WarrantyID between 75 and 100 AND warranty_temp.WarrantyID
between 75 and 100;
Query OK, 119 rows affected (50.97 sec)
Rows matched: 14641 Changed: 119 Warnings: 0
The results of this query are that the OwnerName in record 75 is copied
into the OwnerName for records 75 thru 100. That shouldn't be, there
should be a differant OwnerName for each row being copied into each row of
the target table. Now the table has 119 rows with the same OwnerName.
I have also tried -
mysql> update warranty_old, warranty_temp set
warranty_old.OwnerName=warranty_temp.OwnerName where
warranty_old.WarrantyID = warranty_temp.WarrantyID;
This copied the OwnerName in row 1 into the OwnerName of every row in the
table.
Seems the only way to get this to work is to update every row individually
-
mysql> update warranty, warranty_old set
warranty.OwnerName=warranty_old.OwnerName where warranty.WarrantyID='39'
AND warranty_old.WarrantyID='39';
which works, but there are thousands of rows to update.
Now the memory error - when trying to run a large update, it fails and
the log file contains this message -
040324 14:36:22 Out of memory; Check if mysqld or some other process
uses all
available memory. If not you may have to use 'ulimit' to allow mysqld to
use more
memory or you can add more swap space
I don't know what 'ulimit' is. The server has 512 megs of swap space,
I opened a second Putty terminal and watched top while running the update
statements in another window and MySQL uses 95% of the memory while
processing but the swap never gets touched (shows only 40K used). The
server has 768megs ram, 600mhz Athlon processor.
I just checked the dmesg messages and found this -
pid 18729 (mysqld), uid 88 inumber 32818 on /: filesystem full
so I ran this -
su-2.05b# df -H
FilesystemSize Used Avail Capacity Mounted on
/dev/ad0s1a 508M 346M 121M74%/
devfs 1.0K 1.0K 0B 100%/dev
/dev/ad0s1d14G 2.9G 9.9G22%/usr
File system is not full, what's it talking about?
What would be the recommended remedies?
