Question

I have a primary index on column URL but at the same time I need to have records with URL left blank which won’t be permitted by the index.

I thought of a solution which is to add a new column called ID and make it auto-increment.

So I need to get the ID created with auto-increment on INSERT so that I stick it to column URL too. How can I do this?

If you can think of a better solution please tell

thanks

It is almost certainly better to use the mysql wrapper in your scripting language of choice to acquire the last insert id, but you can SELECT LAST_INSERT_ID(); to get it with mysql itself.
