MDEV-15620 Crash when using "SET @@NEW.a=expr" inside a trigger
The problem resided in this branch of the "option_value_no_option_type" rule:
| '@' '@' opt_var_ident_type internal_variable_name equal set_expr_or_default
Summary:
1. internal_variable_name initialized tmp.var to trg_new_row_fake_var (0x01).
2. The condition "if (tmp.var == NULL)" did not check
the special case with trg_new_row_fake_var,
so Lex->set_system_variable(&tmp, $3, $6) was
called with tmp.var pointing to trg_new_row_fake_var,
which created a sys_var instance pointing to 0x01 instead of
a real system variable.
3. Later, at the trigger invocation time, this method was called:
sys_var::do_deprecated_warning (this=0x1, thd=0x7ffe6c000a98)
Notice, "this" is equal to trg_new_row_fake_var (0x01)
Solution:
The old implementation with separate rules
internal_variable_name (in sql_yacc.yy and sql_yacc_ora.yy) and
internal_variable_name_directly_assignable (in sql_yacc_ora.yy only)
was too complex and hard to follow.
Rewriting the code in a more straightforward way.
1. Changing LEX::set_system_variable()
from:
bool set_system_variable(struct sys_var_with_base *, enum_var_type, Item *);
to:
bool set_system_variable(enum_var_type, sys_var *, const LEX_CSTRING *, Item *);
2. Adding new methods in LEX, which operate with variable names:
bool set_trigger_field(const LEX_CSTRING *, const LEX_CSTRING *, Item *);
bool set_system_variable(enum_var_type var_type, const LEX_CSTRING *name,
Item *val);
bool set_system_variable(THD *thd, enum_var_type var_type,
const LEX_CSTRING *name1,
const LEX_CSTRING *name2,
Item *val);
bool set_default_system_variable(enum_var_type var_type,
const LEX_CSTRING *name,
Item *val);
bool set_variable(const LEX_CSTRING *name, Item *item);
3. Changing the grammar to call the new methods directly
in option_value_no_option_type,
Removing rules internal_variable_name and
internal_variable_name_directly_assignable.
4. Removing "struct sys_var_with_base" and trg_new_row_fake_var.
Good side effect:
- The code in /sql reduced from 314 to 183 lines.
- MDEV-15615 Unexpected syntax error instead of "Unknown system variable" ...
was also fixed automatically

MDEV-24860: Incorrect behaviour of SET STATEMENT in case it is executed as a prepared statement
Running statements with SET STATEMENT FOR clause is handled incorrectly in
case the whole statement is executed in prepared statement mode.
For example, running of the following statement
SET STATEMENT sql_mode = 'NO_ENGINE_SUBSTITUTION' FOR CREATE TABLE t1 AS SELECT CONCAT('abc') AS c1;
results in different definition of the table t1 depending on whether
the statement is executed as a prepared or as a regular statement.
In first case the column c1 is defined as
`c1` varchar(3) DEFAULT NULL
in the last case the column c1 is defined as
`c1` varchar(3) NOT NULL
Different definition for the column c1 arise due to the fact that
a value of the data memeber Item_func_concat::maybe_null depends on
whether strict mode is on or off. Below is definition of the method
fix_fields() of the class Item_str_func that is base class for the
class Item_func_concat that is created on parsing the
SET STATEMENT FOR clause.
bool Item_str_func::fix_fields(THD *thd, Item **ref)
{
bool res= Item_func::fix_fields(thd, ref);
/*
In Item_str_func::check_well_formed_result() we may set null_value
flag on the same condition as in test() below.
*/
maybe_null= maybe_null || thd->is_strict_mode();
return res;
}
Although the clause SET STATEMENT sql_mode = 'NO_ENGINE_SUBSTITUTION' FOR
is parsed on PREPARE phase during processing of the prepared statement,
real setting of the sql_mode system variable is done on EXECUTION phase.
On the other hand, the method Item_str_func::fix_fields is called on PREPARE
phase. In result, thd->is_strict_mode() returns true during calling the method
Item_str_func::fix_fields(), the data member maybe_null is assigned the value
true and column c1 is defined as DEFAULT NULL.
To fix the issue the system variables listed in the SET STATEMENT FOR clause
are set at the beginning of handling the PREPARE phase just right before
calling the function check_prepared_statement() and their original values
restored immediate after return from this function.
Additionally, to avoid code duplication the source code used in the function
mysql_execute_command for setting variables, specified by SET STATEMENT
clause, were extracted to the standalone functions
run_set_statement_if_requested(). This new function is called from
the function mysql_execute_command() and the method
Prepared_statement::prepare().
