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.

between 3 and 803;
It looks like MySQL is using both columns in the key for that query, since
the key_len is 8, but for some reason it says it is still using where.
What happens when you only select these fields: seq_id, ref_id,
start_position, end_position?

Hi all,
i use select * from table_name where start_postion between min_postion and
max_postion to select all the record in the ranges,
when the ranges is very large,such as 800(about 1000 record in it), the
query is so slow,
when i use mysql administrator i find that traffic is higher when
1. Don't use SELECT *. Only grab the cols that you only need. Also
make sure you have an index on min_position and max_position. After
that if your query isn't faster please show us the output of running
EXPLAIN select * from table_name where start_postion between
min_postion and
max_postion .
thanks for reply,
i hava an index on the start_position,the min_postion and the max_postion is
constant value, the output of the query is:
explain select * from REF_SEQ where START_POSITION between 3 and
803;
You are still doing SELECT * . Do you really need to return all of the
columns in that table or just COL1, COL2, COL5 for example. Only grab
the columns you are actually going to use.

Numeric indexing is a lot faster. You definitely shouldn't use text or

Hi List,
I am wondering if someone can help me with a query to check what databases
are on the MySQL server and then check which of those databases are either
partially or completely within the date range i require.
The scenario is as follows:

db2 : 2007-02-01 to
Sounds like you should create a MERGE table that links all the
underlying tables together. Then you just query the merge table and
MySQL handles which tables it needs to pull data from. You also then
don't need to query for the tables.

Try this:
