Hi Gautam
nope yours is not a bug. That's all fine. Hex numbers are 64 bit
unsigned.
So for -1 you have to insert cast(0x as signed).

Hi everyone,
I'm fairly new to MySQL and I have a procedure that writes some status
info to a table. The problem is, I just want the values and row to be
replaced, rather than constantly adding a new row. I tried using REPLACE
as well as different timestamp methods, but I always get a new
We have a pretty large database (several terabytes and hundreds of tables).
When I do a simple query from the information schema, e.g. select table_name
from tables, it can minutes to come back with the answer. Yet, if I do a

Hello,
We are planning on trying to do an Oracle to MySQL migration in the near
future. The issue of a Mysql equivalent to Oracle's flashback was being
discussed. After some digging it appears that there is no such feature

Hi Dave,
You have no primary key on your table, thus MySQL has no way of knowing
when the row is unique and needs to be updated rather than inserted.
REPLACE INTO effectively does the following:
- insert into table
- did a primary key violation occur?
--- yes - delete existing row from
Ack! Such a simple but important step. No wonder it wasn't replacing the
existing row.
That worked great, thank you very much.
Also, thanks to Brent who replied first. I ended up going with the
primary key over the unique index, but I'm sure that would have worked
as well.

Hi Shain,
If you are using InnoDB its possible to patch to allow this functionality.

I am pretty new in optimizing tables with index and may need some help.
This is my query:

If I have an index(blockid),
EXPLAIN will return the following information:

CHANGE MASTER TO MASTER_HOST='';
RESET SLAVE only clears away relay logs.
CHANGE MASTER TO MASTER_HOST='' will delete the master.info

Hi,
you're using Sqlserver syntax for handling reserved words.
In MySQL you use backtick` for the same, i.e.
select `t0`.`amount` etc.
