I have a table with OWN_ID and OWN_Email -
own_id | own_email
-----------------------------------------------
3ace7cf80edd | email#example.com
3acf6af33ff7 | email#example.com
3acda2524e00 | email#example.com
3ad75583c9a7 | spam#example.com
3ad74b018999 | spam#example.com
etc.
the problem is that it should contain only a single ID per Email, also I need to replace all OWN_ID values in another table by highest OWN_ID value of the OWN_Email

delete t1 from table t1, table t2
where t1.own_email= t2.own_email
and t1.own_id < t2.own_id
update othertable, table
set othertable.own_id= table.own_id
where othertable.own_email= table.own_email;
Could accomplish this fairly simple using a transaction that nukes the whole table.
BEGIN;
SELECT own_email, max(own_Id) INTO temptable FROM table GROUP BY own_email
TRUNCATE table;
INSERT INTO table SELECT * FROM temptable;
DELETE temptable;
COMMIT;
But, that Isn't the best way -- you can also do it by deleting just the right rows.
DELETE FROM table AS d WHERE EXISTS (
SELECT own_id FROM table AS t
WHERE NOT EXISTS (
SELECT max(own_id) FROM table AS i
GROUP BY own_email
WHERE t.own_email = i.own_email
)
AND d.own_id = t.own_id
AND d.own_email = t.own_email
);
Here we delete all own_ids, that aren't the max(own_id) for an E-mail.
This can be accomplished with NOT IN (understanding the caveat on nulls), or an anti-join on the table being deleted from

i went to do this query for sum chemps in my table
select sum(likes) from statistiques where pag_id in (12,20) and created="2013-12-02"
but i went have multiple sum like
select sum(likes,posts) from statistiques where pag_id in (12,20) and created="2013-12-02"
but he isn't worked
English is not my native language, sorry for any mistakes.
Your syntax is wrong. Try
select sum(likes), sum(posts) from ...
here is my query
insert into invoices
set Invoice_number = '823N9823',
price = '11,768.00',
code = 'ret_4_business',
created_at = '2010-09-27';
but my price in my db is 11, not 11768
how do i handle money in mysql? the field is a decimal

Any non-number character will terminate the parsing and save only part of the number. Remove the comma characters from the query.

I want to start the auto incremenet from 20000.
How do I do that? Can I edit the table some how to start incrementing from 20000?
ALTER TABLE batchinfo AUTO_INCREMENT = 20000;
See also Autoincrement
See the last line of your query:
AUTO_INCREMENT=15034
Change it to:
AUTO_INCREMENT=20000
Easy as that! :)

INSERT INTO batchinfo (datapath) values('test');
SELECT * FROM batchinfo;
I don't know how to do it from the CREATE statement, but after that you can do this:
ALTER TABLE `batchinfo` AUTO_INCREMENT = 20000;
