Hello!
I am looking for an easy solution for eliminate duplicates but on a row level.
I am having 2 tables. 1 destination for all not duplicated info (a)
and 1 for input table (b) which might have duplicates related to table
a. Now I am using this kind of insert:
INSERT INTO a
SELECT fields
FROM
If the ID doesn't represent anything, you can
CREATE TABLE new_table SELECT DISTINCT Row1, Row2 FROM old_table
And then recreate your index(es).
All your autoincrement IDs will be changed.

Sample Data:
ID-Row1-Row2
1-A-B
2-A-B
Row1 and Row2 are duplicate, so you only want one. Which ID do you want?

hey all,
I have a table "mytable" that looks like this:
id tinyint primary key auto_increment
row1 varchar 150
row2 varchar 150
I would like to remove all duplicates, which means that if n records
have the same row1 and row2, keep only one record and remove the
duplicates. Any idea how to do this?

Yes. Some ways involve subqueries, others temporary tables. What version
are you on? What are your table definition(s) (use SHOW CREATE TABLE to
dump the defs)? How
Subquries will help you .

I have been researching on how to deal with duplicate data. While I have a
case where there can be duplicate data, and I want to get rid of it, the
general ideas I seem to find are as follows, plus my own, which I would like
opinions on since I have not seen it mentioned.
