Hi,
I have been backing up via the dubious method of copying the database data folder onto
another machine where it is properly backed up onto DLT.
(yes, I know I should have used mysqldump!)
Recovering some tables today I copied the files back into their position (including the ibdata1 file and

Hi,
Is it possible to obtain the last_insert_id() for a particular column in
a particular table?
eg, say i wanted to obtain the last insert id of a column called id in
table reference, something along the lines of:
last_insert_id(reference.id)
The reason I ask is because I want to initially

Hi, I have a db where I have converted all the tables innodb. I have 2 tables in particular called gene and name.
They both have a primary key call id. I want the primary key from name to be deleted when the corresponding key is deleted from gene.
It doesn't seem to be happening as yet!

In fact, I'm not sure you can actually create the constraint as you
currently describe it

hi,
2 ways to do this:
a) don't store the file actually in the db but store the path to it.
b)use the function LOAD_FILE(filename) to get the contents of a file as
a string value and store as a blob.
decide which to use depending on how many pics you have

Hi,
the latest version of mysql supports ssl connections.
'phpMyAdmin' is a browser based gui written in php. If your apache has
mod_ssl then you could connect securely.

Hi,
thanks for all of the replies to my query.
I'm not sure that I explained my problem very well as the solutions
received are solutions to the problem I described, but not the one I
meant :-) (I don't think anyway)
I have a table in the format:
family | member | score
another pair of SQL statements per result. If you are
looking for order statistics on the order of the average number of members
per family, then the single-statement approach will almost certainly be a
better choice.

Hi,
I have a table containing data on a number of families.
I want to retrieve members of each family that have the two highest

Is there a function similar to max() or greatest() that will return the
top 2 values when grouping by family
