host you are trying to connect from. Something like

MySQL Server can be 32 or 64 bit and it shouldn't make a difference to PERL.
However, if you can run 64 bit, you should.
PERL and it's modules all need to be the same architecture. It doesn't matter
if they're 32 bit or 64 bit, as long as it's consistent with itself.
I see no reason why

As far as I know, you can't,
you can do it with symbolic linking but not at run time.
So if you have a clue you can (pre)build empty databases using symbolic
linking and switching to the right one at run time.

You can't make the database, table or field names dynamic with
prepare, only values. Prepare allows you to cache the execution plan,
which wouldn't be valid on a different table.

Can you show the CREATE TABLE for your REF_SEQ table?
The explain output says using where which means that MySQL will have to
post-filter rows after the storage engine retrieves them. It also means the
query may benefit from different/better indexing.
On Mon, Jul 13, 2009 at 12:04 AM, TianJing
the REF_SEQ is defined below, the col DNA_SEQ is a string such as
ATGCGGTTA,
| REF_SEQ | CREATE TABLE `REF_SEQ` (
`SEQ_ID` int(11) NOT NULL auto_increment,
`REF_ID` int(11) NOT NULL,
`START_POSITION` int(11) NOT NULL,
`END_POSITION` int(11) NOT NULL,
`DNA_SEQ` text,
`DNA_QUALITY`
I see that index_ref_start is defined on Ref_Id and Start_Position. Mysql
only uses the left-most column of this index. Drop and re-add this key only
defined as
INDEX idx_ref_start(start_position)
and see if that helps.
Your explain you sent this time is not even using the index.
In your
