What is main difference between INSERT INTO table VALUES .. and INSERT INTO table SET ?
Example:
INSERT INTO table (a, b, c) VALUES (1,2,3) INSERT INTO table SET a=1, b=2, c=3
And what about performance of these two?

Hi All,
I am inserting a row with a char column for a hash based on (among other things) the row's auto id.
I know I can insert it, fetch the insert_id, calculate the hash, and update it.
Does anyone know of a way to do this in a single query? You would...

The only way to get a generated ID value from an AUTO_INCREMENT field in MySQL is to do the INSERT and then call last_insert to do.
No, there's no function in MySQL that gives you the current_insert_id() .

In order to get ids for multiple inserts, you will have to call INSERT_ID() after each statement is executed.
The $db->Insert_ID() will return you last insert id only so if you are inserting many records.

(MYSQL) Is there any significant performance differences, or other reasons not to use the INSERT ... ON DUPLICATE UPDATE sql to update by PK/insert new stuff?

INSERT ON DUPLICATE KEY UPDATE ....
In fact this is just a UPDATE , followed by an INSERT should the UPDATE fail.
INSERT ON DUPLICATE KEY UPDATE will locate the record and update it just as a simple UPDATE would do.
No, there is none.

As far.
Doing disabling the index and doing a bulk insert and reenabling the index after you're done.
It doesn't really matter if there's one insert or many inserts within a single transaction.

Just call your appropriate function for your API to get the last insert ID instead LAST_INSERT_ID" might....
If you really wanted to do select last_insert_id, you should do it at the API level.

I have a list that is frequently insertion sorted. Is there a good position (other than the end) for adding to this list to minimize the work that the insertion sort has to do?

There are two.
The drawback is that you must copy the whole array for every insert.
This would the new elements first.
The best place to insert would be where the element belongs in the sorted list.

Within the trigger, you can use a table called 'inserted' to access the values of the new records and the new version of the updated records.
