Hi Jerry,
I guess modification of the table is needed! What are you trying to achieve by

If the primary key is rarely used then maybe adding another column with a

would work and at least let you do some

Right. Any GA release will not get features added, as this would change
functional behavior and also introduce the risk of losing stability.

You could do the partitioning logic on the application side.
For example you can create a new table every month with a
different suffix corresponding to the year/month number.
Then you add the info about this new table into a master

No, I'm afraid. MyISAM tables cannot be cut in several pieces. But check ot
the InnoDB table type, because they work very similar to Oracle. In

Hi,
Does MySQL offering a similar functionality as Oracle does with table partitioning?
Oracle can split a table into several pieces where the pieces are - usually -
identified by a range of valus.
For example, one may split a table holding data on a daily basis into monthly
