allowed in a partition function then it is very important to consider
|
||||
whether this should be inherited to the new class. If not the function
|
||||
below should be defined in the new Item class.
|
||||
|
||||
The general behaviour is that most integer functions are allowed.
|
||||
If the partition function contains any multi-byte collations then
|
||||
the function check_part_func_fields will report an error on the
|
||||
partition function independent of what functions are used. So the
|
||||
only character sets allowed are single character collation and
|
||||
even for those only a limited set of functions are allowed. The
|
||||
problem with multi-byte collations is that almost every string
|
||||
function has the ability to change things such that two strings
|
||||
that are equal will not be equal after manipulated by a string
|
||||
function. E.g. two strings one contains a double s, there is a
|
||||
special german character that is equal to two s. Now assume a
|
||||
string function removes one character at this place, then in
|
||||
one the double s will be removed and in the other there will
|
||||
still be one s remaining and the strings are no longer equal
|
||||
and thus the partition function will not sort equal strings into
|
||||
the same partitions.
|
||||
|
||||
So the check if a partition function is valid is two steps. First
|
||||
check that the field types are valid, next check that the partition
|
||||
function is valid. The current set of partition functions valid
|
||||
assumes that there are no multi-byte collations amongst the partition
|
||||
fields.
