Recently, I got the following error. I found the solution to solve
the problem by increasing the log file size. However, I want to know
why this error will happen. I can't find the explanation for that
error. Anyone can give me some information about the error?

Hello All,
I have a MYISAM table (employment_summary) with over 6 Lac records. I use it
to do fast keyword searches on employments and want to retrieve the results
grouped by the executive. The executive table is also a huge INNODB table
and has over 6 Lac records. If I do any join operations

Assuming you have a database, let's call it DAT1 which contain all MyISAM
tables,
you could make a copy of an entire database to DAT2
On host2 create DAT2 using
CREATE DATABASE DAT2;
Then copy all data from DAT1 to DAT2 like this.
mysqldump -hhost2 -u... -p... --triggers --routines DAT1 |
Thank you.
I have made some tests, and I have inserted 1 records in a MyISAM table,
in a InnoDB table, and in an InnoDB table using a transaction.
I have seen that the insert in an InnoDB table without using a transaction
takes much much more than in a MyISAM table.
I knew that it will
- Stop you mysql server
- change working directory to $MYSQL_DATA_DIR
- run myisamchck with */*.MYD
This will run a check on all your table files

Is there some quick way to do the following in MySQL? (I know I can
use PHP to search through the result set, but I wanted to see if
there's a quick way using some sort of query)
Let's say I know that Joe is from Maine.
I want to do a query of all employees from Maine, ordered by hiring
it gives
the following errors for all the databases ..
myisamchk: error: './diaendomet/users.MYD' is not a MyISAM-table
myisamchk: error: './diaendomet/users.MYD' is not a MyISAM-table
phpmyadmin reports the tables as being MyISAM..
any sugetions

I want to do a query of all employees from Maine, ordered by hiring date,
and figure out where Joe falls in that list. (i.e. which record number
is he?)
If 'Joe' is a unique name LOL...
SELECT 1 + COUNT(*)
FROM employees
WHERE name 'Joe' AND state = 'MA' AND hiredate datevalue;

This may sound a little cheesy, but hear me out.
Create a temp table in memory holding the result of the your employee query
like this:
CREATE TEMPORARY TABLE tmpEmpFromState
(
EMPNAME VARCHAR(60),
HIRED DATE,
ID INT NOT NULL AUTO_INCREMENT,
PRIMARY KEY (ID),
KEY OrderOfHire(HIRED,ID)
)
Remember
ME is Maine
MA is Massachusettes

I don't think that will work. If there are 1,000 records that qualify but
none for Joe, then it will return 1,001. If Joe is in record 1 of the
retrieved record set, and there are 999 other people who match the WHERE
clause, then it will retrieve 1,000.
Am I missing something?

Sorry it is */*.MYI instead of */*.MYD

Greetings Brent;
Many thanks for your input. I decided that I would indeed create the table
from scratch, making certain to apply the 'proper' settings, and then
reload all of the data. This completed yesterday, with the following
results:
Row_format: Dynamic
Rows: 18866709
The path myisamchk is reporting do look a bit funny...is this you
own users table or the mysql users table?
You might want to check you my.cnf file to see if different data
directories have been specified under the various tools headings.

At first I thought I had spotted the obvious in the above - the MAX_ROWS I
used is smaller than the Max_data_length that resulted, presumably MySQL
being smarter than I
I have, after further googling, discovered that the 4.2 billion figure
that MySQL uses as 'max_rows' is, indeed, max_rows and not a max database
size in bytes. In theory I have solved my problem, and wasted however many
peoples bandwidth by putting all these eMails to the MySQL list.
Mea culpa,
This table size is based on your filesystem limits. This is a limit of
the OS, not MySQL.

In the first eMail I mentioned that I had excluded filesystem size limits
by manually producing a 14GB tar file. If it was only that simple :)

Oh, I didn't see the first comment. My mistake. It's likely a 32bit
integer size limit of some sort then. 32bit = 4gbytes

You can try changing the myisam_data_pointer_size setting, but the
max_rows/avg_row_length should have worked.
Unless it's your OS restricting the mysql user to a 4GB file size. You can use ulimit or getrlimit to determine OS limits for a
user. If a user hits a limit imposed by the OS, I think

make an alias for the field you want as sort key and use that. you
don't need to do the calculation twice. I would not be surprised if
