sql_lex.h --> included by session.h

401
* It's needed by item.h and field.h, which are both inter-dependent
402

* What is needed is a separate header file that is included

This enum is used to report information about monotonicity of function
952
represented by Item* tree.
953
Monotonicity is defined only for Item* trees that represent table
954
partitioning expressions (i.e. have no subselects/user vars/PS parameters
955
etc etc). An Item* tree is assumed to have the same monotonicity properties
956
as its correspoinding function F:
958
[signed] int64_t F(field1, field2, ...) {
959
put values of field_i into table record buffer;
960
return item->val_int();
964
At the moment function monotonicity is not well defined (and so may be
965
incorrect) for Item trees with parameters/return types that are different
966
from INT_RESULT, may be NULL, or are unsigned.
967
It will be possible to address this issue once the related partitioning bugs
968
(BUG#16002, BUG#15447, BUG#13436) are fixed.

These tables are an interface provided by the system

These tables do *not* honor:
1040
- LOCK Table t FOR READ/WRITE
1041
- FLUSH TABLES WITH READ LOCK
1042
- SET GLOBAL READ_ONLY = ON
1043
as there is no point in locking explicitely

an INFORMATION_SCHEMA table.
1045
Nothing is directly written to information schema tables.
1046
Note that this value is not used currently,
1047
since information schema tables are not shared,
1048
but implemented as session specific temporary tables.
