Question

when partitioning tables in MySQL using a list, how can I generate a partition for remaining items?

E.G:

CREATE TABLE tbl
(
 ID integer
)
PARTITION BY LIST (ID)
(  
  PARTITION P1 values in (1),  
  PARTITION P2 values in (2),  
  PARTITION P3 values in (3),  
  PARTITION Pother values in (<all remaining values of ID>)
);

In Oracle, I use values in (default), but that does work in MySQL.

Unlike range partitioning, there is no “catch-all” in list partitioning. To quote the documentation:

Unlike the case with RANGE partitioning, there is no “catch-all” such
as MAXVALUE; all expected values for the partitioning expression
should be covered in PARTITION … VALUES IN (…) clauses. An INSERT
statement containing an unmatched partitioning column value fails with
an error…

Unfortunately, I believe, you’re not able to combine a list and a range partition either. I’m not entirely certain why you would want to use a list partition in this particular instance; wouldn’t a range partition work just a well?

CREATE TABLE tbl
(
 ID integer
)
PARTITION BY RANGE (ID)
(  
  PARTITION P1 values less than (2),  
  PARTITION P2 values less than (3),  
  PARTITION P3 values less than (4),  
  PARTITION Pother values less than maxvalue
);

I’m assuming that this is just an example. Partitioning each key in a primary key is a little pointless.
