Check if a partition function is allowed
SYNOPSIS

DESCRIPTION
......@@ -847,9 +847,31 @@ public:
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.
*/
virtual bool check_partition_func_processor(byte *bool_arg)
{ *(bool *)bool_arg= FALSE; return 0; }
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.
