If the second or the third argument of a BETWEEN predicate was
a constant expression, like '2005.09.01' - INTERVAL 6 MONTH,
while the other two arguments were fields then the predicate
was evaluated incorrectly and the query returned a wrong
result set.
The bug was introduced in 5.0.17 when in the fix for 12612.

Fix for bug #14360: Date Between Interval Broken.
- Item_date_add_interval::eq() introduced.
The function agg_cmp_type in item_cmpfunc.cc neglected the fact that
the first argument in a BETWEEN/IN predicate could be a field of a view.
As a result in the case when the retrieved table was hidden by a view
over it and the arguments in the BETWEEN/IN predicates are of
the date/time type the function did not perform conversion of
the constant arguments to the same format as the first field argument.
If formats of the arguments differed it caused wrong a evaluation of
the predicates.

too many open statements". The patch adds a new global variable
@@max_prepared_stmt_count. This variable limits the total number
of prepared statements in the server. The default value of
@@max_prepared_stmt_count is 16382. 16382 small statements
(a select against 3 tables with GROUP, ORDER and LIMIT) consume
100MB of RAM. Once this limit has been reached, the server will
refuse to prepare a new statement and return ER_UNKNOWN_ERROR
(unfortunately, we can't add new errors to 4.1 without breaking 5.0). The limit is changeable after startup
and can accept any value from 0 to 1 million. In case
the new value of the limit is less than the current
statement count, no new statements can be added, while the old
still can be used. Additionally, the current count of prepared
statements is now available through a global read-only variable
@@prepared_stmt_count.

sql/item_row.cc:
Implement Item_row::cleanup(): we should reset used_tables_cache
before reexecution of a prepared statement. In case ROW
arguments contain a placeholder, used_tables_cache has PARAM_TABLE
bit set in statement prepare. As a result, when executing a statement,
the condition push down algorithm (make_cond_for_table) would think
that the WHERE clause belongs to the non-existent PARAM_TABLE and
wouldn't attach the WHERE clause to any of the real tables,
effectively optimizing the clause away.
sql/item_row.h:
Remove a never used member 'array_holder'. Add declaration for
Item_row::cleanup.
Idea of the fix is for master to send FD event with `created' as 0
to reconnecting slave (upon slave_net_timeout, no master crash) to avoid destroying temp tables.
In a case of a connect by slave to the master after its crash temp tables have been already
cleaned up so that slave can not keep `orphan' temp tables.

When TRUNCATE TABLE was called within an stored procedure the
auto_increment counter was not reset to 0 even if straight
TRUNCATE for this table did this.
This fix makes TRUNCATE in stored procedures to be handled exactly
in the same way as straight TRUNCATE. We achieve this by rolling
back the fix for bug 8850, which is no longer needed since stored
procedures don't require prelocked mode anymore (and TRUNCATE is
not allowed in stored functions or triggers).

Additional fix for INSERT DELAYED with subselect.
Originally detected in 5.1, but 5.0 could also be affected.
The user thread creates a dummy table object,

Mutli-table uses temporary table to store new values for fields. With the
new values the rowid of the record to be updated is stored in a Field_string
field. Table to be updated is set as source table of the rowid field.
But when the temporary table creates the tmp field for the rowid field it
converts it to a varstring field because the table to be updated was created by
the v4.1. Due to this the stored rowids were broken and no records for
update were found.
The flag can_alter_field_type is added to Field_string class. When it is set to
0 the field won't be converted to varstring. The Field_string::type() function
now always returns MYSQL_TYPE_STRING if can_alter_field_type is set to 0.
The multi_update::initialize_tables() function now sets can_alter_field_type
flag to 0 for the rowid fields denying conversion of the field to a varstring
field.
sql/field.h:
Fixed bug #16281: Multi-table update broken in 5.0 on tables imported from 4.1
The flag can_alter_field_type is added to Field_string class. When it is set to

The bug was caused by wrong behaviour of mysql_insert() which in case
of INSERT DELAYED into a view exited with thd->net.report_error == 0.
This blocked error reporting to the client which started waiting
infinitely for response to the query.
mysql-test/r/insert.result:
Fixed results for the added test case.
mysql-test/t/insert.test:
Added test case.
sql/sql_insert.cc:
Fixed BUG#13683: INSERT DELAYED into a view creates an infinite loop.
Changed mysql_insert(): delayed_get_table() applied to a view exits
with ER_WRONG_OBJECT error (and with thd->net.report_error == 1) and
in this case we must just exit from mysql_insert(). Prior to this
change, instead of exiting open_and_lock_tables() was invoked which
cleared thd->net.report_error to zero and caused the bug.
The code in opt_sum_query that prevented the COUNT/MIN/MAX
optimization from being applied to outer joins was not adjusted
after introducing nested joins. As a result if an outer join
contained a reference to a view as an inner table the code of
opt_sum_query missed the presence of an on expressions and
erroneously applied the mentioned optimization.

Added a test case for bug #18237.
mysql-test/t/view.test:
