19d61b1b81 Bug#20691: DATETIME col (NOT NULL, NO DEFAULT) may insert garbage when \
specifying DEFAULT

This was not specific to datetime.  When there is no default value 
for a column, and the user inserted DEFAULT, we would write 
uninitialized memory to the table.  

Now, insist on writing a default value, a zero-ish value, the same 
one that comes from inserting NULL into a not-NULL field.

(This is, at best, really strange behavior that comes from allowing 
sloppy usage, and serves as a good reason always to run one's server 
in a strict SQL mode.)


mysql-test/r/default.result:
  Verify that all kinds of types work, even others other than datetime.
mysql-test/t/default.test:
  Verify that all kinds of types work, even others other than datetime.
sql/item.cc:
  Even if we warn that there is no default value in the table definition,
  we have to insert /something/.

59b45b5b0a Bug #20191: getTableName gives wrong or inconsistent result when using VIEWs
When compiling GROUP BY Item_ref instances are dereferenced in 
setup_copy_fields(), i.e. replaced with the corresponding Item_field 
(if they point to one) or Item_copy_string for the other cases.
Since the Item_ref (in the Item_field case) is no longer used the information
about the aliases stored in it is lost.   
Fixed by preserving the column, table and DB alias on dereferencing Item_ref

7614eb0d1d Bug#21505 Create view - illegal mix of collation for operation 'UNION'
The problem was that any VIEW columns had always implicit derivation.
  Fix: derivation is now copied from the original expression
  given in VIEW definition.
  For example:
  - a VIEW column which comes from a string constant
    in CREATE VIEW definition have now coercible derivation.
  - a VIEW column having COLLATE clause
    in CREATE VIEW definition have now explicit derivation.

c095f98ff7 Bug #22457: Column alias in ORDER BY works, but not if in an expression
The parser is allocating Item_field for references by name in ORDER BY
 expressions. Such expressions however may point not only to Item_field 
 in the select list (or to a table column) but also to an arbitrary Item. 
 This causes Item_field::fix_fields to throw an error about missing 
 column.
 The fix substitutes Item_field for the reference with an Item_ref when 
 not pointing to Item_field.

f51d0812a7 Bug #21809: Error 1356 while selecting from view with grouping though underlying
select OK.
The SQL parser was using Item::name to transfer user defined function attributes
to the user defined function (udf). It was not distinguishing between user defined 
function call arguments and stored procedure call arguments. Setting Item::name 
was causing Item_ref::print() method to print the argument as quoted identifiers 
and caused views that reference aggregate functions as udf call arguments (and 
rely on Item::print() for the text of the view to store) to throw an undefined 
identifier error.
Overloaded Item_ref::print to print aggregate functions as such when printing
the references to aggregate functions taken out of context by split_sum_func2()
Fixed the parser to properly detect using AS clause in stored procedure arguments
as an error.
Fixed printing the arguments of udf call to print properly the udf attribute.

7efdc62f9d BUG#21081: SELECT inside stored procedure returns wrong results
Re-execution of a parametrized prepared statement or a stored routine
with a SELECT that use LEFT JOIN with second table having only one row
could yield incorrect result.

The problem appeared only for left joins with second table having only
one row (aka const table) and equation conditions in ON or WHERE clauses
that depend on the argument passed.  Once the condition was false for
second const table, a NULL row was created for it, and any field involved
got NULL-value flag, which then was never reset.

The cause of the problem was that Item_field::null_value could be set
without being reset for re-execution.  The solution is to reset
Item_field::null_value in Item_field::cleanup().

7a11df8c93 Fixed bug#21475: Wrongly applied constant propagation leads to a false comparison.
A date can be represented as an int (like 20060101) and as a string (like
"2006.01.01"). When a DATE/TIME field is compared in one SELECT against both
representations the constant propagation mechanism leads to comparison
of DATE as a string and DATE as an int. In this example it compares 2006 and
20060101 integers. Obviously it fails comparison although they represents the
same date.


Now the Item_bool_func2::fix_length_and_dec() function sets the comparison
context for items being compared. I.e. if items compared as strings the
comparison context is STRING.
The constant propagation mechanism now doesn't mix items used in different
comparison contexts. The context check is done in the
Item_field::equal_fields_propagator() and in the change_cond_ref_to_const() 
functions.

Also the better fix for bug 21159 is introduced.

35209c68ea Fixed bug#12185: Data type aggregation may produce wrong result
The Item::tmp_table_field_from_field_type() function creates Field_datetime
object instead of Field_timestamp object for timestamp field thus always
changing data type is a tmp table is used.

The Field_blob object constructor which is used in the 
Item::tmp_table_field_from_field_type() is always setting packlength field of
newly created blob to 4. This leads to changing fields data type for example
from the blob to the longblob if a temporary table is used.

The Item::make_string_field() function always converts Field_string objects 
to Field_varstring objects. This leads to changing data type from the 
char/binary to varchar/varbinary.

Added appropriate Field_timestamp object constructor for using in the 
Item::tmp_table_field_from_field_type() function.

Added Field_blob object constructor which sets pack length according to
max_length argument.

The Item::tmp_table_field_from_field_type() function now creates
Field_timestamp object for a timestamp field.

The Item_type_holder::display_length() now returns correct NULL length NULL
length. 

The Item::make_string_field() function now doesn't change Field_string to
Field_varstring in the case of Item_type_holder. 

The Item::tmp_table_field_from_field_type() function now uses the Field_blob
constructor which sets packlength according to max_length.

ae9724cce1 Fix for bug#18437 "Wrong values inserted with a before update trigger on
NDB table".

SQL-layer was not marking fields which were used in triggers as such. As
result these fields were not always properly retrieved/stored by handler
layer. So one might got wrong values or lost changes in triggers for NDB,
Federated and possibly InnoDB tables.
This fix solves the problem by marking fields used in triggers
appropriately.

Also this patch contains the following cleanup of ha_ndbcluster code:

We no longer rely on reading LEX::sql_command value in handler in order
to determine if we can enable optimization which allows us to handle REPLACE
statement in more efficient way by doing replaces directly in write_row()
method without reporting error to SQL-layer.
Instead we rely on SQL-layer informing us whether this optimization
applicable by calling handler::extra() method with
HA_EXTRA_WRITE_CAN_REPLACE flag.
As result we no longer apply this optimzation in cases when it should not
be used (e.g. if we have on delete triggers on table) and use in some
additional cases when it is applicable (e.g. for LOAD DATA REPLACE).

Finally this patch includes fix for bug#20728 "REPLACE does not work
correctly for NDB table with PK and unique index".
  
This was yet another problem which was caused by improper field mark-up.
During row replacement fields which weren't explicity used in REPLACE
statement were not marked as fields to be saved (updated) so they have
retained values from old row version. The fix is to mark all table
fields as set for REPLACE statement. Note that in 5.1 we already solve
this problem by notifying handler that it should save values from all
fields only in case when real replacement happens.


include/my_base.h:
  Added HA_EXTRA_WRITE_CAN_REPLACE, HA_EXTRA_WRITE_CANNOT_REPLACE - new
  parameters for ha_extra() method. We use them to inform handler that
  write_row() which tries to insert new row into the table and encounters
  some already existing row with same primary/unique key can replace old
  row with new row instead of reporting error.
mysql-test/r/federated.result:

sql/sql_insert.cc:
  Explicitly inform handler that we are doing REPLACE (using ha_extra() method)
  in cases when it can promote insert operation done by write_row() to replace.
  Also when we do REPLACE we want to store values for all columns so we should
  inform handler about it.
  Finally we should mark fields used by ON UPDATE/ON DELETE triggers as such
  so handler can properly retrieve/restore values in these fields during
  execution of REPLACE and INSERT ... ON DUPLICATE KEY UPDATE statements.
sql/sql_load.cc:
  Explicitly inform handler that we are doing LOAD DATA REPLACE (using
  ha_extra() method) in cases when it can promote insert operation done by
  write_row() to replace.
  Also when we do replace we want to save (replace) values for all columns
  so we should inform handler about it.
  Finally to properly execute LOAD DATA for table with triggers we should
  mark fields used by ON INSERT triggers as such so handler can properly
  store values for these fields.

  mysql_alter_table() function no longer takes handle_duplicates argument.
sql/sql_table.cc:

1c6beaee06 Fixed bug#19077: A nested materialized derived table is used before being populated.
The convert_constant_item() function converts constant items to ints on
prepare phase to optimize execution speed. In this case it tries to evaluate
subselect which contains a derived table and is contained in a derived table. 
All derived tables are filled only after all derived tables are prepared.
So evaluation of subselect with derived table at the prepare phase will
return a wrong result.

A new flag with_subselect is added to the Item class. It indicates that
expression which this item represents is a subselect or contains a subselect.
It is set to 0 by default. It is set to 1 in the Item_subselect constructor
for subselects.
For Item_func and Item_cond derived classes it is set after fixing any argument
in Item_func::fix_fields() and Item_cond::fix_fields accordingly.
The convert_constant_item() function now doesn't convert a constant item
if the with_subselect flag set in it.

90ffe5392a Remove 'const' that prevents Microsoft VC realize that
Item_trigger_field::set_required_privilege(const bool rw) is an
overloading of Settable_routine_parameter::set_required_privilege(bool rw).

afe2520ecf Bug#14635: Accept NEW.x as INOUT parameters to stored procedures
from within triggers

Add support for passing NEW.x as INOUT and OUT parameters to stored
procedures.  Passing NEW.x as INOUT parameter requires SELECT and
UPDATE privileges on that column, and passing it as OUT parameter
requires only UPDATE privilege.


mysql-test/r/sp-error.result:
  Update the result for new message.
mysql-test/r/trigger-grant.result:
  Add result for bug#14635.
mysql-test/r/trigger.result:

mysql-test/t/trigger-grant.test:
  Add test case for bug#14635.
mysql-test/t/trigger.test:
  Add test case for bug#14635.
sql/item.cc:
  Add implementations of set_value() and set_required_privilege() methods
  of Settable_routine_parameter interface.
  
  Use Item_trigger_field::want_privilege instead of
  Item_trigger_field::access_type.
  
  Reset privileges on Item_trigger_field::cleanup().
sql/item.h:
  Add interface class Settable_routine_parameter and interface query
  method to Item class.  Item_splocal and Item_trigger_field implement
  this interface.
  
  For Item_trigger_field:
   - add read_only attribute and is_read_only() method.
   - remove access_type and add original_privilege and want_privilege
     instead.
   - add set_value() method.
   - add reset_privilege() method.
sql/item_func.cc:
  Add implementations of set_value() method of Settable_routine_parameter
  interface.
sql/item_func.h:
  Item_func_get_user_var implements Settable_routine_parameter interface.
sql/share/errmsg.txt:
  Update english ER_SP_NOT_VAR_ARG message.
sql/sp_head.cc:
  Use Settable_routine_parameter interface for parameter update.
sql/sql_yacc.yy:
  Set read_only and want_privilege members in Item_trigger_field
  appropriately.  For NEW.x trigger variable used in left-hand-side
  of SET statement the latter is set to UPDATE_ACL, otherwise it is
  set to SELECT_ACL (but see Item_trigger_field::set_required_privilege(),
  where it may be updated to different value).
