Description
Under terms of this task we'll add some more abstraction methods in a few classes to integrate the upcoming data type associative_array easier.
Doing these changes separately before the main patch for assiciative_array will help to split a big patch into two smaller independent patches, thus making them both easier to read.
Details
- Add new classes sp_type_def and sp_type_def_list. Move the member sp_pcontext::m_records to the new class sp_type_def_list, derive sp_pcontext from it. Put the new classes definition into a new file sp_type_def.h.
- Add new methods in my_var_sp:
virtual bool set_row(THD *thd, List<Item> &select_list)
virtual bool check_assignability(THD *thd,
const List<Item> &select_list,
bool *assign_as_row) const
- Add a new method in Field:
// E.g. Item_field, Item_field_row |
virtual Item_field *make_item_field_spvar(THD *thd, |
const Spvar_definition &def); |
- Add new methods in Type_handler:
virtual bool has_null_predicate() const { return true; } |
|
|
virtual bool sp_variable_declarations_finalize(THD *thd, |
LEX *lex, int nvars, |
const Column_definition &def) |
const; |
// SELECT 1 INTO spvar; |
virtual my_var *make_outvar(THD *thd, |
const Lex_ident_sys_st &name, |
const sp_rcontext_addr &addr, |
sp_head *sphead,
|
bool validate_only) const; |
// SELECT 1 INTO spvar.field; |
virtual my_var *make_outvar_field(THD *thd, |
const Lex_ident_sys_st &name, |
const sp_rcontext_addr &addr, |
const Lex_ident_sys_st &field, |
sp_head *sphead,
|
bool validate_only) const; |
|
|
virtual Item *make_typedef_constructor_item(THD *thd, |
const sp_type_def &def, |
List<Item> *arg_list) const; |
