  2. 2Dynamic partition calculation resulting in 0 partitions
How to reproduce
trigger — this will error
trigger — this will error
CREATE TABLE t (id INT)
PARTITION BY HASH(id) PARTITIONS 0;  -- 0 is not valid

expected output

ERROR 1511 (HY000): Number of partitions = 0 is not allowed value

Specify at least 1 partition
CREATE TABLE t (id INT)
PARTITION BY HASH(id) PARTITIONS 4;  -- Must be >= 1
