Dear Suresh,
Thank you.
In MySQL Replication, as the slave itself takes the writes from master
but in how much time period does slave goes to master. is there any
parameter where I can set this. that after every 60 seconds slave
should write data from master to its own local database.
Hi,
I have created a query to read and update a stock item by using the FOR UPDATE
statement. According to the MySql documention only the rows that are selected
using the FOR UPDATE should be locked for other sessions, but somehow whole the
table is locked. This post gives some general
Hi Manasi,
Inside MySQL, there are no such parameters and the Slave delay depends on
different things like network between Master and Slave, load of the MySQLD
server etc...
To make the slave behind for a particular period of time, use mk-slave-delay
tool from the the maakit. It help your slave to

You *should* be using a package manager (perfectly fine RPMs available for
all your needs), but if you must do this, it's a reasonably safe bet to
right-align and zero-pad all your number to 4 digits, at which point you're
free to concatenate them and treat them as a single number.

I am using RPM. And for Centos 5 it was installing a lower version
of mysql than what was installed with the system. That is why I want

latest version all the time, but not sure whether that will work on
the 4.5 version.

Hi,
The function is probably behaving as intended, but its confusing the
hell out of me. ;) Anyway, say I have two tables; orders and lineitems
Orders has two columns: orderid(primary key) and ordertotal
Lineitems has two columns: orderid and itemid
For every orderid in the orders table,

John,
What's happening is that the tables do not have a one-to-one
relationship, so the JOIN duplicates rows from Orders to match the
rows in Lineitems. You need to ensure the aggregation is consistent
across the two datasets. Try this:
SELECT
Sum(a.ordertotal) as total,

I don't see a valid need for using FOR UPDATE here. In fact, FOR
UPDATE is the cause of many grievances, and I would advise you to
avoid it by any means possible. Among other things, it will cause
serious performance problems when your server gets busy. And as you
can see, it's hard to

Hi Baron,
Thank you for your answer.
The problem is that multiple users can read and update the same field
simultaneously (worse case) which could lead to unpredictable problems.
